    Before FLAUM, KANNE, and SYKES, Circuit Judges.
    SYKES, Circuit Judge. Barbara Kaiser had surgery to im-
    plant the Prolift Anterior Pelvic Floor Repair System, a
    transvaginal mesh medical device that supports the pelvic
    muscles. Within a few years of her surgery, Kaiser began
    experiencing severe pelvic pain, bladder spasms, and pain
    during intercourse. Her physician attributed these condi-
    tions to contractions in the mesh of the Prolift. Kaiser had
    revision surgery to remove the device, but her surgeon could

    not completely extract it. He informed her that the painful
    complications she was experiencing were likely permanent.
    Kaiser sued Ethicon, Inc., Prolift’s manufacturer, and
    Johnson & Johnson, its parent company, seeking damages
    under the Indiana Products Liability Act, IND. CODE §§ 34-
    20-1-1 to 34-20-9-1. (Johnson & Johnson has no distinct role
    in this litigation, so we refer to the defendants collectively as
    “Ethicon.”) After a two-week trial, a jury found Ethicon
    liable for defectively designing the Prolift device and failing
    to adequately warn about its complications. The jury award-
    ed a hefty sum: $10 million in compensatory damages and
    $25 million in punitive damages, though the judge granted
    Ethicon’s motion for remittitur and reduced the punitive
    award to $10 million.
    Ethicon’s appeal is a broad-spectrum attack on the judg-
    ment, starting with an argument about federal preemption
    and moving through several issues of Indiana product-
    liability law, a claimed evidentiary error, and challenges to
    the compensatory and punitive damages. We reject these
    arguments and affirm.
    One issue in particular warrants special mention upfront.
    Our caselaw interprets the Indiana Product Liability Act to
    require a plaintiff in a design-defect case to produce evi-
    dence of a reasonable alternative design for the product. The
    Indiana Supreme Court disagrees. See TRW Vehicle Safety
    Sys., Inc. v. Moore, 
    936 N.E.2d 201
    , 209 (Ind. 2010). The state
    supreme court’s decision controls on a matter of state law, so
    we apply TRW rather than our own contrary precedent.

    I. Background
    A. Prolift
    Barbara Kaiser suffers from pelvic-organ prolapse, a
    nonlife-threatening condition that occurs when pelvic mus-
    cles loosen, causing nearby organs to press into the vagina.
    This condition can lead to several medical complications like
    uncomfortable pelvic pressure and incontinence.
    Ethicon developed Prolift as a treatment option for pa-
    tients with this condition, and in 2009 Kaiser had surgery to
    implant the device. Some detail about Prolift is necessary to
    understand her case and the arguments raised on appeal.
    The device is essentially a precut section of polypropylene
    mesh connected to six mesh arms. A surgeon inserts it
    through the vagina, pulls it through the vaginal wall, and
    anchors the arms to muscles in the hip, thigh, and groin. The
    device was designed to reinforce the pelvic muscles and
    prevent further organ displacement.
    Ethicon began marketing Prolift in 2005. It included an
    “Instructions for Use” package insert that warned: “Potential
    adverse reactions are those typically associated with surgi-
    cally implantable materials, including infection potentiation,
    inflammation, adhesion formation, fistula formation, ero-
    sion, extrusion and scarring that results in implant contrac-
    tion.” It also cautioned that “[t]ransient leg pain may occur
    and can usually be managed with mild analgesics.”
    Patients soon reported serious problems with the Prolift.
    Relevant here, the mesh would often contract, causing severe
    pain and bladder problems. Scar tissue could also form
    around the device, preventing a complete removal if compli-
    cations occurred. In these cases Prolift’s complications

    frequently became permanent. Following years of com-
    plaints and FDA scrutiny, Ethicon took Prolift off the market
    in 2012.
    B. Regulatory Background
    The FDA cleared Prolift for sale in 2007. The clearance
    process features prominently in this appeal, so we take a
    moment to describe the FDA’s role in regulating medical
    devices. The Medical Device Amendments of 1976 (“MDA”),
    21 U.S.C. §§ 360c–360k, 379–379a, establishes the framework
    for federal regulation of medical devices. As amended, the
    MDA requires the FDA to place a device into one of three
    classes reflecting different levels of regulation.
    Class I covers devices for which the MDA’s “general con-
    trols” that apply to all medical devices “are sufficient to
    provide reasonable assurance of the safety and effectiveness
    of the device.” 21 U.S.C. § 360c(a)(1)(A)(i). These general
    controls include measures like the MDA’s prohibition on
    misbranding a device. The FDA typically places low risk
    devices like bandages and tongue depressors in Class I.
    The FDA places a device in Class II when the MDA’s
    “general controls by themselves are insufficient to provide
    reasonable assurance of … safety and effectiveness” but
    enough information exists “to establish special controls to
    provide such assurance.” 
    Id. § 360c(a)(1)(B).
    “Special con-
    trols” are regulations tailored to the device such as perfor-
    mance standards and postmarket surveillance. See 
    id. Most medical
    devices fall into Class II.
    Finally, a Class III device is one for which “insufficient
    information exists to determine” that either general or
    special controls “would provide reasonable assurance of …
    No. 18-2944                                                   5
    safety and effectiveness.” 
    Id. § 360c(a)(1)(C)(i).
    These devices
    “present[] a potential unreasonable risk of illness or injury”
    or are “purported or represented to be for a use in support-
    ing or sustaining human life or for a use which is of substan-
    tial importance in preventing impairment of human health.”
    
    Id. § 360c(a)(1)(C)(ii).
    Before marketing, a Class III device
    undergoes “a rigorous regime of premarket approval.”
    Riegel v. Medtronic, Inc., 
    552 U.S. 312
    , 317 (2008).
    The particulars of the premarket approval process aren’t
    important here; it’s enough to note that it requires extensive
    submissions by the device manufacturer and a thorough
    review by the FDA. See generally 21 U.S.C. §§ 360c, 360e. The
    FDA has broad discretion to withhold approval throughout
    the process. See 21 C.F.R. § 861.1(b) (permitting the FDA to
    set performance standards for Class II and III devices); see
    also Nicholas R. Parrillo, Federal Agency Guidance and the
    Power to Bind: An Empirical Study of Agencies and Industries,
    36 YALE J. ON REG. 165, 186–87 (2019).
    The MDA automatically places a new medical device in
    Class III. 21 U.S.C. § 360c(f)(1). But three broad exceptions
    largely overshadow this rule. To start, medical devices on
    the market before the MDA’s enactment in 1976 are subject
    only to the MDA’s general controls until the FDA promul-
    gates device-specific regulations to classify and regulate
    them. 
    Id. § 360e(b).
        Post-1976 devices can escape rigorous premarket review
    through the MDA’s “premarket notification” process. Al-
    most every manufacturer of a new device must submit a
    notification to the FDA at least 90 days before marketing the
    device. See 21 C.F.R. § 807.81(a); see also 
    id. § 807.81(a)(3)
    (requiring a manufacturer to file a premarket notification
    6                                                  No. 18-2944
    when it alters an existing device if the alteration “could
    significantly affect the safety or effectiveness of the device”
    or if it creates a “major change or modification in the intend-
    ed use of the device”). The FDA may clear a device for sale
    without premarket approval based on this notification if it is
    satisfied the device falls into one of the two other exceptions.
    First, the MDA exempts from premarket review any de-
    vice that receives what’s known as a “§ 510(k) clearance”
    from the FDA. To get this clearance, a device must be “sub-
    stantially equivalent” to either a pre-1976 device that the
    FDA hasn’t yet classified or a Class I or II device already on
    the market. § 360c(f)(1). Most medical devices enter the
    market through this exception. See 2 JAMES T. O’REILLY &
    KATHARINE A. VAN TASSEL, FOOD AND DRUG ADMINISTRATION
    § 18.22, at 464 (4th ed. 2019).
    Second, if a device isn’t substantially equivalent to an
    unclassified pre-1976 device or a Class I or II device, it can
    still avoid premarket review through “de novo” § 510(k)
    clearance. See 21 U.S.C. § 360c(f)(2)(A). Specifically, a manu-
    facturer may petition the FDA that a device meets the crite-
    ria for Class I or II. If the FDA agrees, the device is exempted
    from premarket review. Id.; O’REILLY & VAN TASSEL, supra,
    § 18.26, at 470–71.
    The § 510(k) clearance process is central to several issues
    raised in this appeal. If the FDA is satisfied that a new device
    is substantially equivalent to a device that is already in
    Class I or II or meets the standards for these classes through
    “de novo” § 510(k) review, then it will clear the device for
    marketing without stringent premarket review. To be sub-
    stantially equivalent, the device must have “the same in-
    tended use as the predicate device” and either (1) have “the
    No. 18-2944                                                   7
    same technological characteristics” as the predicate device or
    (2) be “as safe and effective” as the predicate and “not raise
    different questions of safety and effectiveness.” 21 U.S.C.
    § 360c(i)(1)(A).
    The relevance to safety of the § 510(k) clearance process
    varies based on context. That’s due in part to the MDA’s
    three-tiered system for classifying medical devices. If the
    FDA places a device in Class I after a de novo § 510(k)
    review, we know the agency has concluded that the MDA’s
    minimal general controls are enough to “provide reasonable
    assurance of … safety.” § 360c(a)(1)(A). Likewise, when the
    FDA places a device in Class III following full premarket
    review, we know that the agency lacks a reasonable assur-
    ance of the device’s safety. But the FDA’s decision to place a
    device in Class II tells us only that it had enough information
    about the device to design special controls to provide rea-
    sonable assurance of safety. It’s hard to draw inferences
    about a device’s safety without knowing what concerns
    triggered its Class II designation and what special controls
    the FDA thought were necessary.
    A device cleared for market through the § 510(k) “sub-
    stantial equivalence” process raises additional complica-
    tions. To start, two of the three ways for a new device to be
    substantially equivalent to a predicate device have nothing
    to do with product safety. First, a device can receive clear-
    ance if it is substantially equivalent to a pre-1976 device that
    the FDA hasn’t yet classified “regardless of how unsafe or
    ineffective the grandfathered device happens to be.”
    Eghnayem v. Bos. Sci. Corp., 
    873 F.3d 1304
    , 1318 (11th Cir.
    2017) (quotation marks omitted). Second—and more perti-
    nent to Prolift—the FDA can clear a device if it has “the
    8                                                 No. 18-2944
    same technological characteristics as [a] predicate device.”
    § 360c(i)(1)(A)(i). This comparison does not consider safety.
    The MDA defines “different technological characteristics” as
    “a significant change in the materials, design, energy source,
    or other features of the device from those of the predicate
    device.” 21 U.S.C. § 360c(i)(1)(B). Underscoring the distinc-
    tion between safety and similarity of technological character-
    istics, the FDA does not generally require safety information
    in a § 510(k) substantial-equivalence premarket notification.
    See 21 C.F.R. § 807.92(a).
    Finally, the MDA’s authorization of “piggybacking”—
    clearing a device based on its substantial equivalence to a
    predicate device that itself received clearance through
    substantial equivalence—increases the gulf between § 510(k)
    clearance and comprehensive safety review. Through piggy-
    backing, a medical device moves incrementally further and
    further away from the “original” predicate device that the
    FDA actually classified.
    In light of these features of the system, it’s no surprise
    that the FDA has promulgated a disclaimer that § 510(k)
    clearance “does not in any way denote official approval of
    the device.” 
    Id. § 807.97.
    In fact, it’s unlawful for a device
    manufacturer to make such a representation. See 
    id. (“Any representation
    that creates an impression of official approval
    of a device because of complying with the premarket notifi-
    cation regulations is misleading and constitutes misbrand-
    ing.”); see also O’REILLY & VAN TASSEL, supra, § 18.22, at 464
    (“It is important to note that in the § 510(k) process, the
    device is not officially approved by the FDA as being safe
    and effective.”).
    No. 18-2944                                                               9
    C. Prolift
    Prolift did not weather the full premarket review process.
    Quite the contrary: Ethicon started marketing Prolift in 2005
    without submitting any premarket notification to the FDA,
    reasoning that the device didn’t depart materially from a
    transvaginal mesh product that the agency had previously
    cleared. In fact, Ethicon did not submit a § 510(k) premarket
    notification for Prolift until 2007 when the FDA demanded
    one.
    Its 2007 submission asserted that Prolift was substantially
    equivalent to three devices: the Gynecare Gynamesh PS
    Prolene Soft Mesh, the AMS Apogee Vault Suspension
    System, and the AMS Perigee System. 1 According to Ethi-
    con, Prolift had the same technological characteristics as
    these predicates.
    The FDA cleared Prolift based on this submission, send-
    ing a form letter that did not identify which particular
    predicate device it accepted for the substantial-equivalence
    determination. But the agency did indicate that Prolift’s
    “original” predicates were a group of surgical meshes the
    FDA classified in a 1988 rulemaking. See 21 C.F.R. § 878.3300.
    When it promulgated that rule, the FDA cautioned that the
    “surgical mesh has not been implanted in a sufficient num-
    ber of patients by a sufficient number of medical practition-
    ers to provide adequate evidence on the long-term
    biocompatibility of these devices.” General and Plastic
    Surgery Devices, 53 Fed. Reg. 23856, 23862 (June 24, 1988).
    1Ethicon’s premarket notification for Prolift listed a fourth predicate, the
    Ultrapro Mesh, but it used that device only to clear the Prolift +M Pelvic
    Floor Repair System, a different device than the Prolift at issue here.
    10                                                No. 18-2944
    Due to “insufficient evidence of safety and effectiveness,”
    the FDA assigned these surgical meshes to Class II. 
    Id. Because the
    FDA did not specify the predicate device it
    used for Prolift’s § 510(k) clearance, the chain connecting the
    1988 surgical meshes to Prolift is not clear. We do know that
    Prolift used the piggybacking method to achieve clearance;
    that is, each of Prolift’s three proposed predicates received
    FDA clearance through a substantial-equivalence determina-
    tion. The manufacturers of those three predicates collectively
    proposed 17 predicates. And again, the FDA did not indicate
    which of the 17 predicates it used to clear these three devic-
    es. Because the FDA’s records for the 17 second-order predi-
    cates are incomplete, we cannot make out a clear picture of
    the next layer. But the available records reveal an additional
    degree of piggybacking—all received FDA clearance
    through a substantial-equivalence determination.
    Based on Ethicon’s 2007 § 510(k) premarket notification,
    the FDA cleared Prolift as a Class II device after finding that
    it was substantially equivalent to existing Class II devices.
    But in 2011 the FDA ordered Ethicon and other transvaginal
    mesh manufacturers to submit plans for postmarket studies
    of the devices. When the FDA rejected Ethicon’s plan for
    Prolift in 2012, Ethicon discontinued the device. In 2016 the
    FDA reclassified all transvaginal mesh into Class III. See
    21 C.F.R. § 884.5980.
    D. Kaiser’s Surgery and Lawsuit
    Kaiser suffered from a severe anterior pelvic-organ pro-
    lapse. Her doctor referred her to Dr. Gregory Bales, a pelvic-
    floor surgeon in her home state of Indiana. In January 2009
    Dr. Bales surgically implanted Prolift to treat Kaiser’s condi-
    No. 18-2944                                                11
    tion. She was then 60 years old. The parties agree that
    Dr. Bales properly implanted Prolift and otherwise met the
    appropriate standard of care.
    In September 2011 Kaiser reported pelvic pain to her
    physician, who attributed the problem to Prolift “bunching.”
    Kaiser’s complications gradually worsened. In October 2013
    she complained of severe pelvic pain and bladder spasms.
    After determining that the Prolift was the likely source of
    these problems, Kaiser’s physician recommended surgery to
    remove the device. In November Dr. Bales performed a
    corrective procedure by using clamps and scissors to remove
    the vaginal tissue surrounding the mesh. But he was only
    able to remove part of the device. He informed Kaiser that
    her pain was likely permanent.
    Kaiser sued Ethicon in the Southern District of West
    Virginia, the venue of a 28,000-case multidistrict litigation
    (“MDL”) against Ethicon. Kaiser and Ethicon agreed that
    Indiana law applied, and the MDL judge construed two
    counts in Kaiser’s complaint as alleging design-defect and
    failure-to-warn claims under the Indiana Product Liability
    Act (“IPLA” or “the Act”). The judge rejected Ethicon’s
    argument that the federal regulatory scheme preempted
    Indiana law. He then dismissed Kaiser’s other claims as non-
    cognizable under the Act and transferred the case to the
    Northern District of Indiana.
    Two of Kaiser’s posttransfer motions are relevant here.
    First, the Indiana district judge granted Kaiser’s motion to
    exclude evidence related to the FDA’s clearance of Prolift,
    reasoning that the § 510(k) process was only minimally
    probative of safety and that introducing evidence about the
    regulatory process posed a significant risk of jury confusion.
    12                                                        No. 18-2944
    Second, the judge ruled that Prolift did not qualify as “state
    of the art” under Indiana law, which blocked Ethicon from
    relying on a rebuttable presumption that the device was not
    defective. See IND. CODE § 34-20-5-1.
    The case proceeded to trial. The jury returned a verdict
    for Kaiser on both the design-defect and failure-to-warn
    theories of liability and awarded $10 million in compensato-
    ry damages and $25 million in punitive damages. 2
    Ethicon moved for judgment as a matter of law under
    Rule 50 of the Federal Rules of Civil Procedure, reiterating
    the argument it raised in the MDL court that the § 510(k)
    process preempts a design-defect claim under state law.
    Ethicon also argued that the IPLA required Kaiser to present
    evidence of a reasonable alternative design for the device
    (she had none), and that the evidence otherwise failed to
    establish that Prolift was defective and unreasonably dan-
    gerous as required for liability. Regarding the failure-to-
    warn theory, Ethicon argued that Prolift’s warnings were
    adequate as a matter of law and that Kaiser’s evidence of
    causation was insufficient. Ethicon also moved for a new
    trial based on the judge’s exclusion of evidence of Prolift’s
    § 510(k) clearance and his refusal to instruct the jury on a
    pair of rebuttable presumptions under the IPLA, including
    the “state of the art” presumption. Finally, Ethicon chal-
    lenged the jury’s award of compensatory damages and
    attacked the award of punitive damages as both substantive-
    ly unwarranted and excessive.
    2 Kaiser’s husband, Anton, brought a derivative claim for loss of consor-
    tium, but the jury found in favor of Ethicon. He did not appeal.
    No. 18-2944                                                 13
    The judge denied the posttrial motions in all respects ex-
    cept one: he agreed that the jury’s award of punitive damag-
    es was excessive and granted a remittitur to $10 million,
    which Kaiser accepted. The judge then entered final judg-
    ment, setting up this multifaceted appeal.
    II. Discussion
    Ethicon’s first attack on the judgment rests on federal
    preemption. Alternatively, Ethicon argues that Kaiser’s
    claims fall short under Indiana law in multiple respects, or at
    the very least a new trial is warranted based on evidentiary
    and instructional errors by the district judge. Lastly, Ethicon
    challenges the compensatory and punitive damages.
    Before addressing this flurry of arguments, we pause to
    sketch the law of product liability in Indiana. The Indiana
    Products Liability Act governs all claims brought by a
    consumer against a manufacturer for physical harm caused
    by its product, regardless of legal theory. IND. CODE § 34-20-
    1-1. Under the Act a manufacturer who places “into the
    stream of commerce any product in a defective condition
    unreasonably dangerous to any user or consumer … is
    subject to liability for physical harm caused by that prod-
    uct.” 
    Id. § 34-20-2-1.
       Ethicon’s state-law challenges to the judgment center on
    whether Prolift was “defective” and “unreasonably danger-
    ous.” Defectiveness “focuses on the product itself.” Gresser v.
    Dow Chem. Co., 
    989 N.E.2d 339
    , 345 (Ind. Ct. App. 2013). A
    product is defective if it is in a condition “not contemplated
    by reasonable persons among those considered expected
    users or consumers of the product” and “will be unreasona-
    bly dangerous … when used in reasonably expectable
    14                                                No. 18-2944
    ways.” IND. CODE § 34-20-4-1. “A product may be defective
    under the IPLA if it is defectively designed, if it has a manu-
    facturing flaw, or if it lacks adequate warnings about dan-
    gers associated with its use.” Brewer v. PACCAR, Inc.,
    
    124 N.E.3d 616
    , 621 (Ind. 2019).
    The Act grounds design-defect and failure-to-warn liabil-
    ity in negligence: a plaintiff must “establish that the manu-
    facturer or seller failed to exercise reasonable care under the
    circumstances in designing the product or in providing the
    warnings or instructions.” IND. CODE § 34-20-2-2. Under
    either theory, a plaintiff must prove that the defendant
    breached the duty of reasonable care owed to him—whether
    in the product’s design or in its warnings—and the breach
    proximately caused his injury. See 
    Brewer, 124 N.E.3d at 621
    .
    (In cases involving a manufacturing defect, the statute
    imposes strict liability; a showing of negligence is not re-
    quired. See IND. CODE § 34-20-2-2.)
    The “unreasonably dangerous” standard incorporates the
    “consumer expectations” test set forth in the Restatement
    (Second) of Torts: A product is unreasonably dangerous when
    it “exposes the user or consumer to a risk of physical harm
    to an extent beyond that contemplated by the ordinary
    consumer who purchases the product with the ordinary
    knowledge about the product’s characteristics common to
    the community of consumers.” IND. CODE § 34-6-2-146; accord
    RESTATEMENT (SECOND) OF TORTS § 402A cmt. i (AM. LAW
    INST. 1965). To decide whether a product is unreasonably
    dangerous, the fact-finder may consider several factors,
    including “the reasonably anticipated knowledge, percep-
    tion, appreciation, circumstances, and behavior of expected
    users.” Koske v. Townsend Eng’g Co., 
    551 N.E.2d 437
    , 440–41
    No. 18-2944                                                 15
    (Ind. 1990). Whether a product is unreasonably dangerous is
    a distinct inquiry and must be established whether the claim
    is based on a manufacturing defect, a design defect, or a
    defective warning.
    A. Design-Defect Liability
    Ethicon reprises several of its arguments for judgment as
    a matter of law on Kaiser’s design-defect claim. Our review
    is de novo; judgment as a matter of law is warranted “only if
    on the basis of the admissible evidence, no rational jury
    could have found for the prevailing party.” Stragapede v. City
    of Evanston, 
    865 F.3d 861
    , 865 (7th Cir. 2017) (quotation
    marks omitted). A threshold legal issue, however, is federal
    preemption.
    1. Preemption
    Under the Supremacy Clause, federal law is “the su-
    preme Law of the Land … , any Thing in the Constitution or
    Laws of any State to the Contrary notwithstanding.” U.S.
    CONST. art. VI cl. 2. When “state and federal law ‘directly
    conflict,’ state law must give way.” PLIVA, Inc. v. Mensing,
    
    564 U.S. 604
    , 617 (2011). A direct conflict exists where “it is
    impossible for a private party to comply with both state and
    federal requirements.” 
    Id. at 618
    (quotation marks omitted).
    Ethicon maintains that it is impossible for it to comply with
    both the federal regulatory scheme for medical devices—
    here, the § 510(k) clearance process—and the requirements
    of the IPLA.
    We begin by recapping Ethicon’s duties under state and
    federal law. As relevant here, under Indiana tort law,
    Ethicon was required to “exercise reasonable care under the
    circumstances in designing” Prolift. § 34-20-2-2. That is,
    16                                                 No. 18-2944
    Ethicon had a state-law duty to ensure that Prolift’s design
    made the device “reasonably fit and safe for the purpose for
    which [it was] intended.” 
    Brewer, 124 N.E.3d at 623
    (quota-
    tion marks omitted). Meanwhile, federal law required
    Ethicon to obtain FDA clearance before marketing or sub-
    stantially modifying Prolift. § 360c(f)(2)(A); 21 C.F.R.
    § 807.81(a)(3)(ii). To obtain FDA clearance under the § 510(k)
    process, it had to file a premarket notification establishing
    that Prolift was substantially equivalent to an already-
    cleared device or otherwise met the requirements for a
    Class I or II device.
    Ethicon argues that these state and federal duties directly
    conflict: it could not independently redesign Prolift to satisfy
    its duties under the IPLA because the § 510(k) regulatory
    scheme required it to seek FDA clearance before making any
    substantive changes to the device.
    This argument does not come to us on a blank slate. In
    Medtronic, Inc. v. Lohr, 
    518 U.S. 470
    (1996), the Supreme
    Court addressed the § 510(k) clearance process in relation to
    the MDA’s express preemption provision, which preempts
    state regulations that are “different from, or in addition to,
    any [MDA] requirement applicable … to the device.”
    21 U.S.C. § 360k(a)(1). The Court held that the § 510(k)
    regulatory regime does not preempt state tort liability
    through this provision. 
    Lohr, 518 U.S. at 501
    . The Court
    explained that the § 510(k) substantial-equivalence standard
    does not impose any requirements on a medical device but is
    simply an exception to the premarket approval process. 
    Id. at 492–94;
    cf. 
    Riegel, 552 U.S. at 323
    (holding that the MDA
    premarket approval process does preempt state law under
    the express-preemption provision).
    No. 18-2944                                                  17
    Kaiser argues that Lohr forecloses Ethicon’s preemption
    defense without further inquiry. We disagree. Lohr ad-
    dressed a question of express preemption; Ethicon argues
    here for implied preemption. An express-preemption provi-
    sion “supports a reasonable inference[] that Congress did
    not intend to pre-empt other matters,” but it does not “en-
    tirely foreclose[] any possibility of implied pre-emption.”
    Freightliner Corp. v. Myrick, 
    514 U.S. 280
    , 288 (1995); see also
    
    PLIVA, 564 U.S. at 618
    n.5 (“[T]he absence of express pre-
    emption is not a reason to find no conflict pre-emption.”).
    The Court’s decision in Lohr turned on the particular lan-
    guage of the MDA’s preemption provision—more specifical-
    ly, whether the § 510(k) process imposes “any
    requirement[s] applicable … to the 
    device.” 518 U.S. at 486
    (quoting § 360k(a)(1)). Lohr’s reasoning is certainly instruc-
    tive, but it does not tell us whether it was impossible for
    Ethicon to comply with its duties under both federal and
    state law.
    Still, implied preemption does not arise here. “The ques-
    tion for ‘impossibility’ is whether the private party could
    independently do under federal law what state law requires
    of it.” 
    PLIVA, 564 U.S. at 620
    . “[W]hen a party cannot satisfy
    its state duties without the Federal Government’s special
    permission and assistance, which is dependent on the exer-
    cise of judgment by a federal agency, that party cannot
    independently satisfy those state duties for pre-emption
    purposes.” 
    Id. at 623–24.
        Nothing in the § 510(k) regulatory scheme prevented
    Ethicon from complying with the IPLA’s standard of care
    before seeking § 510(k) clearance for Prolift. Indeed, the
    § 510(k) process did not require Prolift “to take any particu-
    18                                                  No. 18-2944
    lar form for any particular reason.” 
    Lohr, 518 U.S. at 493
    . As
    we’ve explained, the § 510(k) process simply asks whether a
    device is substantially equivalent to an approved device or
    otherwise meets the MDA’s broad standards for Class I or II
    devices. See § 360c(f). Federal law did not stop Ethicon from
    satisfying its state-law duties regarding Prolift’s design before
    it filed its premarket notification seeking substantial-
    equivalence clearance. It lost independent control over
    Prolift’s design only after it received § 510(k) clearance from
    the FDA.
    Ethicon’s situation is loosely analogous to that of a
    brand-name drug manufacturer faced with state-law tort
    duties regarding the adequacy of its warnings. A brand-
    name manufacturer can strengthen a warning label without
    waiting for FDA approval. See 21 C.F.R. § 314.70(c)(6)(iii).
    The FDA requires brand-name manufacturers to file a
    supplement explaining a change in warnings and reserves
    the right to reject a labeling change after it is made. 
    Id. § 314.70(c)(7).
        In Wyeth v. Levine, 
    555 U.S. 555
    (2009), the Supreme Court
    considered whether it was impossible for a brand-name
    drug manufacturer to comply with this federal labeling
    regime and its duties under state tort law. The Court rejected
    the manufacturer’s claim of impossibility preemption,
    noting that the FDA permitted a manufacturer “to unilater-
    ally strengthen its warning” to comply with state law. 
    Id. at 573.
    The Court recognized that the FDA could veto such a
    change, but “absent clear evidence that the FDA would not
    have approved a [warning] change,” no direct conflict
    between federal and state duties could be said to exist. 
    Id. at 571.
    No. 18-2944                                                  19
    The same reasoning applies here. The federal regulatory
    regime did not make it impossible for Ethicon to comply
    with its state-law duties before it sought § 510(k) clearance
    for Prolift in 2007. Ethicon does not claim that the FDA
    would have rejected a different design, so on a straightfor-
    ward application of Wyeth, Ethicon hasn’t established a
    direct conflict between its duties under federal and state law.
    See 
    id. at 573
    (“[T]he mere fact that the FDA approved [a
    different] label does not establish that it would have prohib-
    ited such a change.”).
    Ethicon’s response rests largely on an analogy to the
    FDA’s framework for generic drugs, which the Supreme
    Court has held preempts failure-to-warn liability under state
    tort law. See Mut. Pharm. Co. v. Bartlett, 
    570 U.S. 472
    , 486–87
    (2013); 
    PLIVA, 564 U.S. at 618
    . There is some similarity
    between the § 510(k) process for clearing a medical device
    and the FDA’s clearance of generic drugs. A manufacturer
    can receive FDA clearance for a generic drug “by showing
    equivalence to a reference listed drug that has already been
    approved by the FDA.” 
    PLIVA, 564 U.S. at 612
    (citing
    21 U.S.C. § 355(j)(2)(A)).
    But there is a crucial difference: A manufacturer of gener-
    ic drugs has no flexibility when it initially creates a warning
    label. Instead, federal law imposes the “duty of sameness,”
    which requires a generic drug manufacturer to “ensur[e]
    that its warning label is the same as the brand name’s” label.
    
    Id. at 613.
    So if a brand-name warning is insufficient under
    state law, it’s impossible for a generic drug manufacturer to
    simultaneously comply with federal and state law. See
    
    Bartlett, 570 U.S. at 490
    (“Federal law requires a very specific
    label … , and state law forbids the use of that label.”).
    20                                                  No. 18-2944
    Because of this inflexibility, the Court’s generic-drug rul-
    ings turn on whether a “generic manufacturer[] may change
    [its] label[] after initial FDA approval.” 
    PLIVA, 564 U.S. at 613
    . The important point for this case, however, is that
    Ethicon had complete and independent control over Prolift’s
    design before it sought § 510(k) clearance for the device. It
    was not impossible to simultaneously comply with federal
    and state law.
    Ethicon also relies on the Supreme Court’s rejection of
    the “stop selling” theory in Bartlett. The plaintiffs in Bartlett
    resisted federal preemption by asserting that the manufac-
    turer could comply with both federal and state law by
    simply ceasing to manufacture the generic drug at issue. The
    Court explained that this argument would make “impossi-
    bility pre-emption … all but meaningless.” 
    Bartlett, 570 U.S. at 488
    (quotation marks omitted). The Court held that “an
    actor seeking to satisfy both his federal- and state-law obli-
    gations is not required to cease acting altogether in order to
    avoid liability.” 
    Id. At least
    one circuit has relied on Bartlett
    to reject an “exit the market” argument in a case raising a
    preemption defense against a design-defect claim involving
    a pharmaceutical product. Yates v. Ortho-McNeil-Janssen
    Pharm., Inc., 
    808 F.3d 281
    , 300 (6th Cir. 2015).
    Ethicon’s reliance on this aspect of Bartlett is misplaced.
    
    Bartlett, 570 U.S. at 490
    (“[F]ederal law establishes no safe-
    harbor for drug companies … .”); see also Merck Sharp &
    Dohme Corp. v. Albrecht, 
    139 S. Ct. 1668
    , 1678 (2019) (“[W]e
    have refused to find clear evidence of … impossibility where
    the laws of one sovereign permit an activity that the laws of
    the other sovereign restrict or even prohibit.”). The Court
    held only that a plaintiff cannot use the stop-selling rationale
    No. 18-2944                                                  21
    to harmonize otherwise conflicting federal and state laws.
    
    Bartlett, 570 U.S. at 488
    . That holding is of little help where,
    as here, no direct conflict between federal and state law
    exists. As we’ve explained, the requirements of the § 510(k)
    premarket-notification process do not directly conflict with
    Indiana law under the principles announced in Wyeth. The
    design-defect claim is not preempted.
    2. Reasonable Alternative Design
    Moving on to state-law arguments, Ethicon contends that
    the IPLA requires a plaintiff to produce evidence of a rea-
    sonable alternative design for the product in order to prevail
    on a design-defect claim. If this reading of Indiana law is
    correct, Ethicon is entitled to judgment as a matter of law.
    Kaiser did not present evidence of a reasonable alternative
    design for transvaginal mesh.
    As we’ve noted, a product is defective within the mean-
    ing of the IPLA if it is sold “in a condition: (1) not contem-
    plated by reasonable persons among those considered
    expected users or consumers of the product; and (2) that will
    be unreasonably dangerous to the expected user or consum-
    er when used in reasonably expectable ways of handling or
    consumption.” IND. CODE § 34-20-4-1. Put in terms of the
    Act’s negligence standard for design-defect claims, Ethicon
    had a duty to ensure that Prolift’s design made the device
    “reasonably fit and safe for the purpose for which [it was]
    intended.” 
    Brewer, 124 N.E.3d at 623
    (quotation marks
    omitted).
    Nothing in the IPLA expressly requires a plaintiff to
    prove that an alternative product design would have pre-
    vented his injury; indeed, the Act is silent on the subject.
    22                                                 No. 18-2944
    Nevertheless, we have long held that “[t]o demonstrate a
    design defect under Indiana law, the plaintiff must … show
    that another design not only could have prevented the injury
    but also was cost-effective under general negligence princi-
    ples.” Aregood v. Givaudan Flavors Corp., 
    904 F.3d 475
    , 488
    (7th Cir. 2018) (quotation marks omitted). Ethicon invokes
    this line of circuit precedent. Kaiser, in turn, points to the
    Indiana Supreme Court’s decision in TRW Vehicle Safety
    Systems, Inc. v. Moore, 
    936 N.E.2d 201
    , 209 (Ind. 2010), which
    specifically rejected an alternative-design requirement as
    inconsistent with the IPLA standards for design-defect
    liability.
    To understand this split in authority, it’s helpful to trace
    its origin. The story begins with the Indiana Supreme
    Court’s decision in Miller v. Todd, 
    551 N.E.2d 1139
    (Ind.
    1990), which considered the appropriate standard for crash-
    worthiness cases, also known as “enhanced injury” cases.
    These claims seek to hold manufacturers liable “for injuries
    sustained in a motor vehicle accident where a manufacturing
    or design defect, though not the cause of the accident,
    caused or enhanced the injuries.” 
    Id. at 1140.
    Miller held that
    to prove “‘[d]efectiveness’ from a crashworthiness stand-
    point,” a plaintiff must “demonstrate that a feasible, safer,
    more practicable product design would have afforded better
    protection.” 
    Id. at 1143.
        Following Miller’s instructions, we have applied an
    alternative-design requirement in crashworthiness cases
    under Indiana law. See Piltch v. Ford Motor Co., 
    778 F.3d 628
    ,
    632 (7th Cir. 2015); Whitted v. Gen. Motors Corp., 
    58 F.3d 1200
    ,
    1204–05 (7th Cir. 1995); Pries v. Honda Motor Co., 
    31 F.3d 543
    ,
    545 (7th Cir. 1994); Bammerlin v. Navistar Int’l Transp. Corp.,
    No. 18-2944                                                  23
    
    30 F.3d 898
    , 902 (7th Cir. 1994). But we limited Miller to that
    specific context—at least initially. See Anderson v. P.A. Radocy
    & Sons, Inc., 
    67 F.3d 619
    , 625 n.5 (7th Cir. 1995) (“[T]he
    requirement that the plaintiff, in order to establish a defec-
    tive condition, must offer a more cost-effective design ap-
    plies to enhanced injury cases only.”); see also Welch v.
    Scripto-Tokai Corp., 
    651 N.E.2d 810
    , 815 n.5 (Ind. Ct. App.
    1995) (“Although the feasibility of a safer design of a prod-
    uct may be relevant to the ordinary consumer’s expectations
    about that product, such feasibility is not controlling.”).
    We later applied an alternative-design requirement in a
    design-defect case outside the crashworthiness context,
    albeit through the IPLA’s negligence provision. See § 34-20-
    2-2. In McMahon v. Bunn-O-Matic Corp., we cited Miller for
    the proposition that “a design-defect claim in Indiana is a
    negligence claim, subject to the understanding that negli-
    gence means failure to take precautions that are less expen-
    sive than the net costs of accidents.” 
    150 F.3d 651
    , 657 (7th
    Cir. 1998). In the design-defect context, the “failure to take
    [cost-effective] precautions” is another way of saying that
    the manufacturer did not adopt a reasonable alternative
    design. Id.; see 1 DAVID G. OWEN & MARY J. DAVIS, OWEN &
    DAVIS ON PRODUCTS LIABILITY § 8:11, at 746 (4th ed. 2014).
    McMahon involved burn injuries from hot coffee; the plain-
    tiffs sued the manufacturer of the coffee maker alleging that
    the device was unreasonably dangerous because it held the
    coffee temperature too 
    high. 150 F.3d at 653
    . Based on the
    foregoing understanding of the requirements of Indiana law,
    we affirmed a summary judgment for the manufacturer.
    Since McMahon we have generally read the IPLA to re-
    quire evidence of a reasonable alternative design in all
    24                                                   No. 18-2944
    design-defect cases. See, e.g., 
    Aregood, 904 F.3d at 489
    ; see also
    Mesman v. Crane Pro Servs., 
    409 F.3d 846
    , 849 (7th Cir. 2005)
    (holding that a product is negligently designed “only if the
    product could have been redesigned at a reasonable cost to
    avoid the risk of injury”).
    The Indiana Supreme Court rejected that interpretation
    of the Act in its 2010 decision in TRW Vehicle Safety Systems.
    The plaintiff in TRW brought a crashworthiness claim
    against several vehicle and component-part manufacturers,
    including a seat belt manufacturer. Applying Miller, the
    Indiana Court of Appeals held that because the claim “pro-
    ceeded in negligence … , [the plaintiff] was required to
    provide proof of an alternative design.” Ford Motor Co. v.
    Moore, 
    905 N.E.2d 418
    , 427 (Ind. Ct. App. 2009). The manu-
    facturers defended this conclusion in the state supreme
    court, contending that the plaintiff had to provide evidence
    of “a safer, more practicable product design” and “rebut
    evidence that its proposed alternative design … presented
    safety concerns.” 
    TRW, 936 N.E.2d at 209
    .
    The Indiana Supreme Court disagreed, explaining that
    although the Restatement (Third) of Torts proposes an alterna-
    tive-design requirement, the 1998 version of the IPLA “did
    not adopt this analytical framework.” 
    Id. at 209
    n.2. The
    Indiana legislature “instead enacted … a negligence stand-
    ard for product liability claims based on defective design.”
    
    Id. And because
    the Act “prescribes the applicable standard
    of care,” the court explicitly declined “to require proof of
    any additional or more particular standard of care in prod-
    uct liability actions alleging a design defect.” 
    Id. at 209
    .
    Our circuit caselaw cannot be reconciled with TRW. Our
    view that Indiana law imposes an alternative-design re-
    No. 18-2944                                                          25
    quirement rests on an understanding that “negligence means
    failure to take precautions that are less expensive than the
    net cost[] of accidents.” 
    McMahon, 150 F.3d at 657
    ; see also
    
    Bammerlin, 30 F.3d at 902
    (endorsing this approach and
    stating that there is “no reason to think that [Indiana] would
    see things otherwise”). The Indiana Supreme Court has
    unambiguously rejected that reading of state law, clarifying
    that the IPLA’s negligence provision does not incorporate
    the standard proposed by the American Law Institute in the
    Restatement (Third) of Torts and thus does not “require proof
    of any additional or more particular standard of care.” 
    TRW, 936 N.E.2d at 209
    . Requiring a design-defect plaintiff to
    produce evidence of a cost-effective, safer design imposes a
    “more particular standard of care” and is therefore incon-
    sistent with the IPLA as authoritatively construed by the
    state’s highest court.
    “A decision by a state’s supreme court terminates the au-
    thoritative force of our decisions interpreting state law, for
    under Erie our task in diversity litigation is to predict what
    the state’s highest court will do. Once the state’s highest
    court acts, the need for prediction is past.” Reiser v. Residen-
    tial Funding Corp., 
    380 F.3d 1027
    , 1029 (7th Cir. 2004). The
    Indiana Supreme Court has spoken clearly and unequivocal-
    ly: the IPLA does not require evidence of a reasonable alter-
    native design to establish design-defect liability. 
    TRW, 936 N.E.2d at 209
    . Sitting in diversity, we are required to
    follow TRW rather than our own cases to the contrary, which
    are not accurate interpretations of state law. 3
    3 This opinion declines to follow circuit precedent, which must give way
    to an authoritative decision of the Indiana Supreme Court on a matter of
    26                                                          No. 18-2944
    Of course, a plaintiff proceeding under Indiana law re-
    mains free to establish design-defect liability through evi-
    dence of a reasonable alternative design. TRW left this
    method of proof open to plaintiffs, while not requiring it as
    an element of the claim. 
    Id. at 210;
    accord FMC Corp. v. Brown,
    
    551 N.E.2d 444
    , 446 (Ind. 1990). Reasonable alternative
    designs are also “relevant to the issue of whether the design
    in question is unreasonably dangerous.” Marshall v. Clark
    Equip. Co., 
    680 N.E.2d 1102
    , 1106 (Ind. Ct. App. 1997) (quota-
    tion marks and emphasis omitted); see also Gilbert v. Stone
    City Constr. Co., 
    357 N.E.2d 738
    , 744 (Ind. Ct. App. 1976)
    (“Those who come into contact with a product may reasona-
    bly expect its supplier to provide feasible safety devices in
    order to protect them from dangers created by its design.”).
    Although evidence of a cost-effective alternative design can
    be relevant to design-defect liability, TRW holds that the
    IPLA does not require such evidence to prevail on a design-
    defect claim.
    3. Unreasonably Dangerous
    As we’ve explained, the Act’s “unreasonably dangerous”
    standard “focuses on the reasonable expectations of the
    consumer.” 
    Gresser, 989 N.E.2d at 345
    . The parties agree that
    the relevant consumers here are pelvic-floor surgeons.
    Ethicon contends that the jury based its verdict on an im-
    proper understanding of consumer expectations in this
    context. Quoting our decision in Bourne v. Marty Gilman, Inc.,
    Ethicon argues that “a user’s knowledge of a general risk
    precludes recovery even if he did not know the extent or
    state law. Accordingly, we circulated the opinion under Circuit Rule 40(e)
    to all judges in active service. No judge wished to hear this case en banc.
    No. 18-2944                                                   27
    specific degree of that risk.” 
    452 F.3d 632
    , 636 (7th Cir. 2006);
    see also Moss v. Crosman Corp., 
    136 F.3d 1169
    , 1173 (7th Cir.
    1998) (rejecting a claim that a BB gun was unreasonably
    dangerous in a case involving a fatal injury when ordinary
    consumers would know the device could cause serious
    injury). By the same logic, Ethicon reasons that Prolift wasn’t
    unreasonably dangerous if an ordinary pelvic-floor surgeon
    would be aware of the possibility of all relevant risks, even if
    he would be unaware of the precise likelihood or severity of
    those risks. As Ethicon sees it, that describes this case.
    This argument overreads our decision in Bourne. We did
    not hold that “a user’s knowledge of a general risk precludes
    recovery”; that statement came from our description of the
    district court’s decision. 
    Bourne, 452 F.3d at 636
    . Bourne
    explained that under the consumer-expectations test, some
    cases involving obvious risks are “so one-sided that there is
    no possibility of the plaintiff’s recovery.” 
    Id. at 637.
    Even so,
    “a product may be designed with a feature that, although
    obvious, is nonetheless unreasonably prone to cause acci-
    dents.” 
    Id. at 636.
    Bourne does not help Ethicon.
    Nor does Moss advance Ethicon’s position. As we later
    explained in McMahon, our decision in Moss rejected a claim
    that a consumer’s “failure to appreciate the gravity of the
    damage a product could do” could satisfy the consumer-
    expectations test under Indiana law when ordinary consum-
    ers “understood that the product could cause a serious
    injury.” 
    McMahon, 150 F.3d at 657
    . Moss does not, however,
    stand for the proposition that the severity or frequency of a
    product’s risks are irrelevant. Indeed, Ethicon’s argument on
    this point actually contradicts the IPLA, which contemplates
    an inquiry into probability and severity of risk. See IND.
    28                                                No. 18-2944
    CODE § 34-6-2-146 (mandating that a product is unreasona-
    bly dangerous when it “exposes the user or consumer to a
    risk of physical harm to an extent beyond that contemplated
    by the ordinary consumer”) (emphasis added). It was entire-
    ly proper for the jury to consider evidence of the frequency
    and severity of Prolift’s complications when applying the
    consumer-expectations test.
    And on this understanding of Indiana law, a reasonable
    jury could conclude that Prolift created risks beyond the
    expectations of ordinary pelvic-floor surgeons. Dr. Bales
    testified that “none of the surgeons originally implanting the
    Prolift probably were quite as appraised of all the possible
    risks and some of the subsequent problems” associated with
    the device. For example, he testified that he was not aware
    that Prolift was impossible to remove safely in some pa-
    tients, making its complications permanent. Similarly,
    Dr. Bruce Rosenzweig, an expert witness for Kaiser, testified
    that he “did not know of [the] risks that were associated
    with the Prolift device[,] and once [he] found out about
    them, [he] stopped using it.” Finally, Dr. Daniel Elliott,
    another plaintiff’s expert, testified that it would be “impos-
    sible” for every surgeon to know about all of Prolift’s risks.
    To be sure, the evidence wasn’t one-sided. Dr. Bales testi-
    fied that he was aware of many of Prolift’s risks. The jury
    also heard testimony that surgeons could have learned more
    about Prolift’s risks from medical literature. But “whether a
    product is unreasonably dangerous is usually a question of
    fact that must be resolved by the jury.” Baker v. Heye-Am.,
    
    799 N.E.2d 1135
    , 1140 (Ind. Ct. App. 2003). That some evi-
    dence favored Ethicon establishes only that the case present-
    ed factual disputes for the jury to resolve. The jury was free
    No. 18-2944                                                           29
    to infer, for example, that an ordinary pelvic-floor surgeon
    does not have exhaustive knowledge of medical literature.
    On this record a reasonable jury could conclude that Prolift
    was unreasonably dangerous.
    B. Failure-to-Warn Liability
    A product is also defective under the IPLA if a seller does
    not “properly package or label the product to give reasona-
    ble warnings of danger about the product … when the seller,
    by exercising reasonable diligence, could have made such
    warnings or instructions available to the user or consumer.”
    IND. CODE § 34-20-4-2. Put another way, Ethicon had “a duty
    to warn with respect to latent dangerous characteristics of
    the product, even though there is no ‘defect’ in the product
    itself.” Nat. Gas Odorizing, Inc. v. Downs, 
    685 N.E.2d 155
    , 161
    (Ind. Ct. App. 1997). Under Indiana’s learned-intermediary
    doctrine, a medical-device manufacturer can discharge this
    duty by providing adequate warnings to physicians. See 
    id. at 162
    n.10; Phelps v. Sherwood Med. Indus., 
    836 F.2d 296
    , 303
    (7th Cir. 1987). 4
    Ethicon argues that Kaiser’s failure-to-warn claim was
    deficient as a matter of law. More specifically, Ethicon
    contends that no reasonable jury could have found that it
    breached its duty or that any failure to warn caused Kaiser’s
    4 Kaiser asserts that the learned-intermediary doctrine applies only when
    an intermediary has equal knowledge and sophistication as the manufac-
    turer. That’s true only of the “sophisticated intermediary” defense, a
    “related but distinct” doctrine. Nat. Gas Odorizing, Inc. v. Downs,
    
    685 N.E.2d 155
    , 162 n.10 (Ind. Ct. App. 1997). Both doctrines permit a
    manufacturer to warn an intermediary instead of the end consumer, but
    the learned-intermediary doctrine, which “is limited to prescription
    drugs and medical devices,” applies without this qualification. 
    Id. 30 No.
    18-2944
    injuries. It faces an uphill battle on both fronts. Looking first
    to breach, whether a warning is “reasonable” is “generally a
    question of fact for the trier of fact to resolve.” Cook v. Ford
    Motor Co., 
    913 N.E.2d 311
    , 319 (Ind. Ct. App. 2009). It only
    becomes “a question of law when the facts are undisputed
    and only a single inference can be drawn from those facts.”
    
    Id. at 327.
         The warnings in Prolift’s Instructions for Use were brief,
    so we’ll repeat them in full: “Potential adverse reactions are
    those typically associated with surgically implantable mate-
    rials, including infection potentiation, inflammation, adhe-
    sion formation, fistula formation, erosion, extrusion and
    scarring that results in implant contraction.” The Instruc-
    tions also warned that “[t]ransient leg pain may occur and
    can usually be managed with mild analgesics.” Much of the
    evidence at trial supported the jury’s finding that this warn-
    ing was inadequate. For example, Dr. Bales pointed to the
    absence of any warning about Prolift’s potential for perma-
    nent pelvic pain and sexual dysfunction. Similarly,
    Dr. Elliott testified that the Instructions did not provide
    warnings about the frequency, severity, or permanence of
    Prolift’s side effects. Given the limited scope of the warnings
    in Prolift’s Instructions for Use, a reasonable jury could
    conclude that Ethicon breached its duty to warn surgeons of
    its risks.
    Ethicon challenges this conclusion on two grounds. It
    first contends that the “Surgeons’ Resource Monograph”—a
    document it distributed to surgeons only at training
    events—contained more comprehensive warnings about
    Prolift’s risks. But even if we assume that Ethicon can satisfy
    its duty to warn through a limited-distribution monograph
    No. 18-2944                                                 31
    (an open question), Kaiser successfully undermined this
    evidence through effective cross-examination. For example,
    Dr. Salil Khandwala, one of Ethicon’s experts, conceded that
    Ethicon failed to update the monograph when it received
    information regarding heightened complication rates. A
    reasonable jury could conclude that the monograph did not
    tip the scales in Ethicon’s favor.
    Ethicon also argues that its duty to warn did not extend
    to providing information about the frequency, severity, or
    permanence of Prolift’s side effects. This argument relies on
    a different aspect of McMahon. Recall that the claims in
    McMahon arose out of burn injuries from hot coffee; in
    addition to a design-defect claim, the plaintiff argued that
    the manufacturer of the coffee maker failed to warn con-
    sumers about the severity of burns that hot coffee can pro-
    
    duce. 150 F.3d at 654
    . We affirmed the summary judgment
    for the manufacturer, reasoning that the IPLA “expects
    consumers to educate themselves about the hazards of daily
    life … by general reading and experience.” 
    Id. at 656.
        This case is far removed from “the hazards of daily life.”
    Ethicon asks us to rule as a matter of law on the contents of a
    reasonable warning for a specialized medical device. The
    question raises technical and highly fact-bound inquiries.
    We have held in the related context of “sophisticated inter-
    mediaries” that “[w]hether a manufacturer has discharged
    its duty … is almost always a question for the trier of fact.”
    
    Id. (quotation marks
    omitted). That principle applies with
    equal force to the learned-intermediary doctrine. Whether
    Ethicon breached its duty to warn was a question for the
    jury, and we see no reason to disturb its determination on
    this element of the claim.
    32                                                No. 18-2944
    Ethicon’s causation argument is a closer question. As
    with breach, “[c]ausation-in-fact is ordinarily a factual
    question reserved for determination by the jury.” Kovach v.
    Caligor Midwest, 
    913 N.E.2d 193
    , 198 (Ind. 2009). But “where
    reasonable minds cannot disagree as to causation-in-fact, the
    issue may become a question of law for the court.” 
    Id. The causation
    question here is relatively straightforward:
    Would Dr. Bales have used the Prolift device to treat Kaiser’s
    condition if Ethicon had provided additional warnings? The
    answer is more complicated. When asked: “Is there anything
    you would have done differently with respect to
    Ms. Kaiser’s January 2009[] surgery?” Dr. Bales responded:
    “No, not looking back, I don’t think I would have done
    anything differently.” He also admitted that the “medi-
    colegal climate” surrounding Prolift “probably was a factor”
    in his ultimate decision to discontinue using it. And he
    conceded that after discontinuing Prolift, he returned to a
    procedure he felt had “virtually the same complication risks,
    except for … extrusion and erosion.” But when asked if he
    would “have wanted to use Prolift if told about [its] risks,”
    Dr. Bales offered a different response: “My sense is that had
    I had all the subsequent information about how some pa-
    tients fared and how some complications occurred, it’s
    probably safe to say that I may not have started using the
    Prolift.”
    Reasonable minds could read Dr. Bales’s mixed testimo-
    ny and disagree about causation. Again, however, that just
    means the question was one for the jury—and a reasonable
    jury could credit Dr. Bales’s assertion that additional warn-
    ings about complications would have led him to choose a
    different treatment plan.
    No. 18-2944                                                  33
    C. Motion for a New Trial
    As a fallback, Ethicon asks us to reverse for a new trial,
    arguing that the judge failed to instruct the jury on two of
    the IPLA’s evidentiary presumptions and improperly ex-
    cluded evidence of Prolift’s § 510(k) clearance. Different
    standards of review apply. “We review jury instructions de
    novo to determine whether, taken as a whole, they correctly
    and completely informed the jury of the applicable law.”
    Javier v. City of Milwaukee, 
    670 F.3d 823
    , 828 (7th Cir. 2012)
    (quotation marks omitted). We review the district court’s
    evidentiary decisions for abuse of discretion. Smith v. Hunt,
    
    707 F.3d 803
    , 807 (7th Cir. 2013). Under either standard, an
    error warrants a new trial only if it is prejudicial. See 
    id. at 808;
    Javier, 670 F.3d at 828
    .
    1. State-of-the-Art Presumption
    The IPLA provides a rebuttable presumption that “the
    product that caused the physical harm was not defective”
    and “the manufacturer … was not negligent” if the product
    “was in conformity with the generally recognized state of
    the art applicable to the safety of the product at the time the
    product was designed, manufactured, packaged, and la-
    beled.” § 34-20-5-1. The judge declined to instruct the jury on
    this presumption. Ethicon challenged this ruling in its
    posttrial motions and does so again on appeal.
    To justify the instruction, Ethicon needed a “legally suffi-
    cient evidentiary basis” to support the state-of-the-art pre-
    sumption. FED. R. CIV. P. 50(a)(1). The presumption requires
    evidence that the product used “the best technology reason-
    ably feasible at the time the defendant designed” it. Wade v.
    Terex-Telelect, Inc., 
    966 N.E.2d 186
    , 192 (Ind. Ct. App. 2012)
    34                                                  No. 18-2944
    (quotation marks omitted). Ethicon could satisfy this stand-
    ard by providing “[e]vidence of the existing level of technol-
    ogy, industry standards, the lack of other advanced
    technology, the product’s safety record, and the lack of prior
    accidents.” 
    Id. Ethicon’s evidence
    in support of the presumption was
    thin at best. It presented no expert testimony on the issue,
    nor did it produce evidence of existing industry standards.
    Ethicon conceded that it hadn’t conducted any human trials
    before releasing Prolift, so it couldn’t present a safety record.
    Instead, it offered testimony that Prolift was generally an
    improvement over its predecessor. It also provided a lay
    witness’s statement that those who designed Prolift were
    “working to get something out there that’s better … than
    anything that has been out there before.”
    These highly generalized statements fall far short of satis-
    fying the legal standard for the presumption. “State of the
    art evidence must be relevant to the risk at issue.” 
    Id. at 193.
    In Wade, for example, the Indiana Court of Appeals held that
    the presumption did not apply even when the manufacturer
    offered “anecdotal evidence that the same technology had
    been used for almost thirty years and that it … had not
    heard of a report of anyone” being injured by the design
    risk. 
    Id. at 194.
    Ethicon’s evidence is no more specific to the
    risks at issue here. The judge was right to decline to instruct
    the jury on the presumption.
    2. Regulatory-Compliance Presumption
    The IPLA also provides a rebuttable presumption that
    the product was not defective if the manufacturer can estab-
    lish that it “complied with applicable codes, standards,
    No. 18-2944                                                   35
    regulations, or specifications established, adopted, promul-
    gated, or approved … by an agency of the United States or
    Indiana.” § 34-20-5-1. Based on Prolift’s § 510(k) clearance,
    Ethicon faults the judge for not instructing the jury on this
    presumption.
    Ethicon did not request this instruction at the close of ev-
    idence, see FED. R. CIV. P. 51(c)(1), so our review is limited to
    plain error, 
    id. R. 51(d)(2).
    The regulatory-compliance pre-
    sumption requires evidence of compliance with governmen-
    tal standards that “relate to the risk or product defect at
    issue.” 
    Wade, 966 N.E.2d at 195
    ; see also 
    id. (holding that
    a
    regulation wasn’t relevant to the presumption because it was
    “silent” regarding the particular defect at issue, even when it
    had a “primary objective of … prevent[ing] accidents associ-
    ated” with the product). We’ve explained at length that the
    § 510(k) process does not require a medical device “to take
    any particular form for any particular reason.” 
    Lohr, 518 U.S. at 493
    . Prolift’s § 510(k) clearance is insufficient to support
    the presumption. We find no error.
    3. FDA Evidence
    Ethicon also wanted to present evidence of Prolift’s
    § 510(k) clearance for the more general purpose of inviting
    the jury to draw an inference that the device was safe. The
    judge excluded this evidence under Rule 403 of the Federal
    Rules of Evidence, reasoning that because the § 510(k)
    process “speaks to equivalency, not safety,” the probative
    value of this evidence was minimal and substantially out-
    weighed by the risk of confusing or misleading the jury and
    wasting time.
    36                                                No. 18-2944
    That was not an abuse of discretion. To start, evidence of
    Prolift’s § 510(k) clearance faces the same categorical prob-
    lem as any device cleared to market through substantial
    equivalence: The FDA expressly disclaims any intent of
    “approving” devices through the § 510(k) process. See
    21 C.F.R. § 807.97. Prolift’s clearance also contains several
    red flags. The FDA warned that Prolift’s original predi-
    cates—the surgical meshes in the 1988 rulemaking—did not
    come with a reasonable assurance of safety. While incom-
    plete, the § 510(k) history also shows that Prolift’s connec-
    tion to these meshes is attenuated—both it and its three
    possible immediate predicates all piggybacked off of other
    § 510(k)-cleared devices. And importantly, Ethicon’s § 510(k)
    premarket notification never claimed that Prolift was as safe
    as its proposed predicates. Instead, it asserted that Prolift
    had the same technological characteristics.
    Simply put, Prolift’s § 510(k) clearance is remote from
    FDA safety review. The available records indicate only that
    Prolift lies at the end of an undefined chain of devices that
    each received FDA clearance through a process that does not
    necessarily consider product safety. And at the origin of this
    chain is a group of devices that raised serious safety con-
    cerns at the FDA. It was reasonable to conclude that the
    probative value of this evidence was minimal at best and
    that admitting it would precipitate a confusing sideshow
    over the details of the § 510(k) process.
    D. Damages
    1. Compensatory Damages
    Ethicon sought remittitur of the jury’s $10 million award
    of compensatory damages. Applying the federal standard
    No. 18-2944                                                   37
    for reviewing damages awards, the judge denied the motion,
    reasoning that the damages were rationally connected to the
    evidence, not “monstrously excessive,” and comparable to
    awards in other personal-injury cases involving vaginal
    mesh. Marion Cty. Coroner’s Office v. EEOC, 
    612 F.3d 924
    ,
    930–31 (7th Cir. 2010). Ethicon challenges that ruling, which
    we review for abuse of discretion. EEOC v. AutoZone, Inc.,
    
    707 F.3d 824
    , 833 (7th Cir. 2013).
    We note at the outset that it was a mistake to review the
    jury’s award under the federal standard. The Supreme Court
    has held that state standards for reviewing damages awards
    are substantive law for Erie purposes. Gasperini v. Ctr. for
    Humanities, Inc., 
    518 U.S. 415
    , 430–31 (1996). Accordingly,
    “when a federal jury awards compensatory damages in a
    state-law claim, state law determines whether that award is
    excessive.” Rainey v. Taylor, 
    941 F.3d 243
    , 253 (7th Cir. 2019);
    see also Smart Mktg. Grp., Inc. v. Publ’ns Int’l Ltd., 
    624 F.3d 824
    , 832 (7th Cir. 2010); Naeem v. McKesson Drug Co., 
    444 F.3d 593
    , 611 (7th Cir. 2006). So the judge’s use of the federal
    standard was legal error. In fairness, the judge relied on our
    suggestion in Jutzi-Johnson v. United States that portions of
    the federal standard remain viable when a court reviews a
    state-law damages award. 
    263 F.3d 753
    , 760 (7th Cir. 2001);
    accord Arpin v. United States, 
    521 F.3d 769
    , 777 (7th Cir. 2008).
    We take this opportunity to clarify that federal law has no
    place in reviewing a damages award in a state-law claim.
    
    Rainey, 941 F.3d at 252
    –53 (acknowledging the lack of clarity
    in our cases on this point).
    That said, the error was harmless. The damages award
    was not excessive under Indiana law. Indiana courts will not
    disturb a compensatory-damages award “[i]f there is any
    38                                                No. 18-2944
    evidence in the record which supports the amount of the
    award, even if it is variable or conflicting.” Sears Roebuck &
    Co. v. Manuilov, 
    742 N.E.2d 453
    , 462 (Ind. 2001) (quotation
    marks omitted). The evidence here satisfies this deferential
    standard. For example, the jury learned that Kaiser under-
    went painful corrective surgery that removed large portions
    of vaginal tissue. And Kaiser suffers from permanent pelvic
    pain, bladder spasms, and pain during intercourse—all
    Prolift-related conditions. This evidence was enough to
    justify the jury’s $10 million compensatory award.
    Ethicon’s counterargument largely focuses on compari-
    sons to other damages awards. While these comparisons are
    relevant to the federal standard, see, e.g., 
    AutoZone, 707 F.3d at 834
    , Indiana courts heavily disfavor “comparative analy-
    sis” when reviewing a damages award, Weinberger v. Boyer,
    
    956 N.E.2d 1095
    , 1114 (Ind. Ct. App. 2011). The state courts
    instead adopt a “historical regard for the uniqueness of
    every tort claim and … the belief that compensatory damage
    assessments should be individualized and within the prov-
    ince of the factfinder.” 
    Id. Because the
    jury had a reasonable
    evidentiary basis for its decision, we will not disturb the
    compensatory award. See 
    id. at 1112
    (“The jury’s damage
    award will not be deemed the result of improper considera-
    tions if the size of the award can be explained on any rea-
    sonable ground.”).
    2. Punitive Damages
    The judge granted Ethicon’s remittitur motion and re-
    duced the punitive award from $25 million to $10 million,
    which Kaiser accepted. Ethicon argues that an award of
    punitive damages is unwarranted as a substantive matter
    No. 18-2944                                                  39
    and that the size of this award is excessive even after remit-
    titur.
    The parties agree that New Jersey law applies to this is-
    sue, so bear with us as we discuss one more statutory re-
    gime. New Jersey’s Punitive Damages Act establishes a two-
    step process for awarding punitive damages. First, the jury
    must decide whether the defendant’s conduct warrants
    punitive damages, which requires the plaintiff to prove “by
    clear and convincing evidence” that the defendant’s acts or
    omissions caused the harm and were “actuated by actual
    malice or accompanied by a wanton and willful disregard of
    persons who foreseeably might be harmed.” N.J. STAT. ANN.
    § 2A:15-5.12(a). When making this determination, the jury
    must consider four factors:
    (1) The likelihood, at the relevant time, that se-
    rious harm would arise from the defendant’s
    conduct;
    (2) The defendant’s awareness of reckless dis-
    regard of the likelihood that the serious harm
    at issue would arise … ;
    (3) The conduct of the defendant upon learning
    that its initial conduct would likely cause
    harm; and
    (4) The duration of the conduct or any con-
    cealment of it by the defendant.
    
    Id. § 2A:15-5.12(b).
        If the jury finds that punitive damages are warranted, it
    next sets the amount of damages. Besides the four factors
    listed above, the jury must consider “[t]he profitability of the
    40                                                 No. 18-2944
    misconduct to the defendant,” “[w]hen the misconduct was
    terminated,” and “[t]he financial condition of the defend-
    ant.” 
    Id. § 2A:15-5.12(c).
        Finally, as relevant here, the Punitive Damages Act pro-
    vides an affirmative “FDA defense” that applies in two
    situations: (1) when the medical device at issue is “subject to
    premarket approval or licensure” by the FDA or (2) when
    the device “is generally recognized as safe and effective
    pursuant to conditions established” by the FDA. 
    Id. § 2A:58C-5.
        Ethicon raises three arguments in opposition to the puni-
    tive award: the FDA defense precludes punitive damages
    altogether; the evidence is insufficient to support an award
    of punitive damages at step one of the New Jersey frame-
    work; and the remitted award is excessive under step two.
    To the first point, the FDA defense does not apply. The
    § 510(k) process cannot be considered “premarket approval
    or licensure” when the FDA itself cautions that § 510(k)
    clearance “does not in any way denote official approval of
    the device.” 21 C.F.R. § 807.97; see also 
    Lohr, 518 U.S. at 492
    –
    94 (holding that the § 510(k) process is an exception from the
    MDA licensing process). And we reiterate one last time that
    the § 510(k) process is not designed to designate devices as
    “safe and effective.”
    To the second point, as we’ve noted, to justify an award
    of punitive damages under the New Jersey framework,
    Kaiser had to prove that Ethicon’s conduct evinced “wanton
    and willful disregard” of those who might foreseeably be
    harmed by its conduct. N.J. STAT. ANN. § 2A:15-5.12(a). That
    is, Ethicon must have acted or failed to act “with knowledge
    of a high degree of probability of harm to another and
    No. 18-2944                                                  41
    reckless indifference to the consequences of such act or
    omission.” 
    Id. § 2A:15-5.10.
    Although a plaintiff must prove
    the required degree of culpability “by clear and convincing
    evidence,” 
    id. § 2A:15-5.12(a),
    the New Jersey Supreme Court
    has recognized that “determinations about whether there is
    sufficient evidence of egregiousness to permit or to support
    a punitive award are necessarily fact-sensitive,” Quinlan v.
    Curtiss-Wright Corp., 
    8 A.3d 209
    , 230 (N.J. 2010). Thus, “the
    appropriate focus” for legal challenges to punitive-damages
    claims is “whether there was too little evidence of egre-
    giousness presented by plaintiff to get to the jury on the
    issue at all.” 
    Id. at 231.
        Even under the heightened burden of proof, on this rec-
    ord a reasonable jury could find that Ethicon acted recklessly
    when releasing Prolift and crafting its warnings. For exam-
    ple, the jury saw e-mails from Prolift’s inventors alerting
    Ethicon that problems could occur from mesh shrinkage,
    including permanent pain and sexual dysfunction. Dr. Peter
    Hinoul, one of Ethicon’s medical directors, admitted that
    Ethicon knew from the outset that Prolift had a high risk of
    these side effects. He also conceded that Ethicon knew that if
    the device contracted, it could lead to invasive remedial
    surgeries. Dr. Hinoul also testified that Ethicon understood
    when Prolift was released that it would eventually need to
    replace its mesh with a safer material due to these complica-
    tions.
    Notably, an Ethicon medical director proposed updating
    Prolift’s Instructions for Use to account for the risk of sexual
    dysfunction. The jury heard testimony that Ethicon denied
    this request in order to reduce printing costs and avoid
    delaying Prolift’s release. The Instructions instead generical-
    42                                                 No. 18-2944
    ly described Prolift’s “[p]otential adverse reactions” as those
    “typically associated with surgically implantable materials.”
    Ethicon did not warn of Prolift’s risks of sexual dysfunction,
    permanent pain, and other complications. Indeed, the In-
    structions mentioned the risk of postsurgical pain only once,
    in its warning that “[t]ransient leg pain may occur and can
    usually be managed with mild analgesics.”
    A reasonable jury could credit this evidence and con-
    clude that Ethicon knew of the risk of serious complications
    and acted with reckless indifference by failing to warn
    surgeons. See Ripa v. Owens-Corning Fiberglas Corp., 
    660 A.2d 521
    , 532 (N.J. Super. Ct. App. Div. 1995) (holding that suffi-
    cient evidence existed for punitive damages where a manu-
    facturer knew about a serious product risk but failed to warn
    consumers of the danger). Accordingly, we see no basis to
    disturb the jury’s conclusion that Ethicon’s conduct warrant-
    ed punitive damages.
    Finally, Ethicon objects that the punitive award is exces-
    sive even after remittitur. But it raised this objection only in
    its reply brief and even then the argument is undeveloped.
    That’s a waiver. See Harris v. Warrick Cty. Sheriff’s Dep’t,
    
    666 F.3d 444
    , 448 (7th Cir. 2012).
