    CERTIFIED FOR PUBLICATION
    IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA
    SECOND APPELLATE DISTRICT
    DIVISION SIX
    REXINA MIZE et al.,                    2d Civil No. B295829
    (Super. Ct. No. BC649083)
    Plaintiffs and Appellants,        (Los Angeles County)
    v.
    MENTOR WORLDWIDE LLC,
    Defendant and Respondent.
    This case is about preemption and causation:
    whether the Medical Device Amendments (MDA) to the federal
    Food, Drug, and Cosmetic Act (FDCA) preempt the state-law
    products liability claims at issue here, and whether Rexina Mize
    and her husband, Minh Nguyen, sufficiently pled causation to
    survive Mentor Worldwide LLC’s demurrer to those claims. We
    conclude that the tort claims in this case survive preemption
    because they are “‘“‘premised on conduct that both (1) violates the
    [MDA] and (2) would give rise to a recovery under state law even
    in the absence of the [MDA].’”’ [Citation.]” (Glennen v. Allergan,
    Inc. (2016) 
    247 Cal. App. 4th 1
    , 11-12 (Glennen).) We further
    conclude that Mize and Nguyen pled the requisite “‘causal
    connection’” between their injuries and Mentor’s tortious acts to
    survive a demurrer. (Rannard v. Lockheed Aircraft Corp. (1945)
    
    26 Cal. 2d 149
    , 156 (Rannard).) Because the trial court reached
    contrary conclusions, we reverse.
    FACTUAL AND PROCEDURAL HISTORY1
    The Medical Device Amendments of 1976
    Since 1976, the MDA has required the Food and Drug
    Administration (FDA) to provide “detailed federal oversight” of
    medical devices. (Rigel v. Medtronic, Inc. (2008) 
    552 U.S. 312
    ,
    316 (Rigel).) “The devices receiving the most federal oversight
    are those in Class III.” (Id. at p. 317.) Such devices include those
    that pose potentially unreasonable risks of illness or injury.
    (Ibid.) Breast implants are assigned to Class III.
    A Class III device must undergo premarket approval
    to “provide reasonable assurance of its safety and effectiveness.”
    (21 U.S.C.2 § 360c(a)(1)(C).) “Premarket approval is a ‘rigorous’
    process.” 
    (Rigel, supra
    , 552 U.S. at p. 317.) It includes
    submission of an application that includes studies of the device’s
    safety and effectiveness, a statement of its components and
    principles of operation, a description of its manufacturing
    methods, samples of the device, and proposed labels. (Id. at pp.
    317-318.) The FDA will grant premarket approval “only if it
    finds there is a ‘reasonable assurance’ of the device’s ‘safety and
    effectiveness.’” (Ibid.) Once it does, “the MDA forbids the

    amended complaint, which we accept as true in our review of the
    trial court’s order sustaining Mentor’s demurrer. (Blank v.
    Kirwan (1985) 
    39 Cal. 3d 311
    , 318 (Blank).)

    manufacturer to make . . . changes in design specifications,
    manufacturing processes, labeling, or any other attribute that
    would affect safety or effectiveness.” (Id. at p. 319.)
    Before obtaining premarket approval, a Class III
    device manufacturer may apply to use the device in clinical tests
    pursuant to an investigational device exemption (IDE).
    (§ 360j(g).) To qualify for an IDE, the manufacturer must submit
    an application and investigational plan for the device. (See 21
    C.F.R. §§ 812.20(b), 812.25.) The FDA must then determine that
    the benefits to test participants and the knowledge to be gained
    from the tests outweigh the device’s risks. (21 C.F.R. § 812.30.)
    If the FDA approves an IDE application, few changes to the
    investigational plan are permitted. (21 C.F.R. § 812.35(a)(1).)
    Mentor’s MemoryGel breast implants
    In the early 1990’s, Mentor applied for an IDE to
    permit clinical testing of its MemoryGel silicone breast implants.
    The FDA granted Mentor’s application and approved three
    studies: an adjunct study for patients undergoing either breast
    reconstruction after a mastectomy or breast implant revision,3
    approved in July 1992; a core study, approved in August 1992;
    and an IDE study, approved in August 2000.
    In 1998, the FDA sued Mentor, alleging that the
    company failed to meet manufacturing quality standards,
    destroyed evidence of its implants’ high rupture rates, sold
    contaminated implants, and failed to comply with FDA-mandated
    design and materials specifications. The FDA and Mentor
    entered into a consent decree to address the alleged violations,
    which required the company to remedy the deficiencies, comply

    replacement of existing breast implants.

    with federal law, and adhere to good manufacturing practices. If
    Mentor complied with the terms of the decree for five years, the
    FDA would not oppose a petition to dissolve it.4
    Mize’s breast implants
    Two years after the FDA and Mentor finalized the
    consent decree, Mize underwent a bilateral breast augmentation,
    receiving MemoryGel breast implants as part of Mentor’s adjunct
    4 The trial court took judicial notice of the consent decree
    and its subsequent dissolution. We grant Mentor’s unopposed
    request to judicially notice these documents and all others
    properly noticed by the court below. (Rea v. Blue Shield of
    California (2014) 
    226 Cal. App. 4th 1209
    , 1223; see Evid. Code,
    § 459, subd. (a).)
    Mentor also requests that we consider several additional
    documents that were not presented to the court below: (1) five
    documents, other than those cited above, attached to the request
    for judicial notice, (2) pages 53 to 558 of the Respondent’s
    Appendix, and (3) two documents attached to a declaration in
    support of Mentor’s brief on appeal. We deny these requests. As
    to the first set of documents, Mentor “puts forth no reason for its
    failure to request [that] the trial court . . . take judicial notice of”
    them. (Brosterhous v. State Bar (1995) 
    12 Cal. 4th 315
    , 325-326.)
    As to the second, though Mentor lodged these documents with the
    trial court, it did not request that the court take judicial notice of
    them. They are thus not a proper part of the record for review of
    Mentor’s demurrer. (Cloud v. Northrop Grumman Corp. (1998)
    
    67 Cal. App. 4th 995
    , 999 [demurrer “attacks only defects disclosed
    on the face of the pleadings or by matters that can be judicially
    noticed”.]) As to the third, “documents not before the trial court
    cannot be included as part of the record on appeal.” (Pulver v.
    Avco Financial Services (1986) 
    182 Cal. App. 3d 622
    , 632.) We
    disregard all of these documents and the portions of Mentor’s
    brief that cite to and rely on them. (Ibid.)

    study. Mize did not meet the study’s criteria because she did not
    need breast reconstruction or implant revision. She was unaware
    she was participating in the study, and did not know that her
    implants had not been approved for sale by the FDA.
    After her breast augmentation, Mize began to
    experience a variety of health problems, including chronic
    fatigue, muscle and bone pain, joint swelling and stiffness,
    memory loss, and numbness. Her vision deteriorated, and she
    had to get prescription eyeglasses. She lost several business
    opportunities and abandoned her music career. None of Mize’s
    doctors connected her health problems to her implants.
    Premarket approval
    In August 2003, a federal court dissolved Mentor’s
    consent decree with the FDA. Four months later, Mentor sought
    premarket approval for its MemoryGel implants. The FDA
    approved Mentor’s application in November 2006. As a condition
    of approval, the FDA required Mentor to conduct six studies that
    would document the safety and effectiveness of its implants and
    answer questions the earlier clinical trials did not answer. As
    part of these studies, Mentor had to submit adverse event
    reports, either as individual medical device reports that would be
    stored in the FDA’s publicly accessible Manufacturer and User
    Facility Device Experience (MAUDE) database (for deaths and
    unusual adverse events), or as postmarket spreadsheet reports
    that would not be included in the database (for well-known or
    expected adverse events, including implant rupture).
    Mentor failed to properly perform the six studies. It
    did not follow up with enough study participants and did not fully
    report the myriad adverse events—such as silicone toxicity,
    implant removal, autoimmune complaints, ruptures, and
    5
    inflammation—documented in the studies. According to Mize,
    the FDA would have included the adverse events in the MAUDE
    database had Mentor properly reported them.
    The removal of Mize’s implants and ensuing lawsuit
    In December 2016, an MRI revealed that Mize’s
    breast implants had ruptured. She had them removed the
    following month. After their removal, Mize’s mental clarity
    improved. She no longer suffered from chronic fatigue, and no
    longer needed her prescription eyeglasses.
    Mize and Nguyen sued Mentor. In the third
    amended complaint, Mize alleged causes of action for negligence
    and negligence per se based on Mentor’s negligent failure to warn
    and negligent manufacturing, strict products liability for failure
    to warn, and strict products liability for manufacturing defects.
    Nguyen alleged a derivative cause of action for loss of consortium.
    In support of her manufacturing defect claims, Mize
    alleged that Mentor: (1) manufactured its MemoryGel implants
    in a manner that “differed from the specifications agreed to by
    the FDA”; (2) “us[ed] materials and components [that] differed
    from those approved by the FDA”; (3) “fail[ed] to follow good
    manufacturing practices”; (4) “fail[ed] to properly meet the
    applicable standard of care by not complying with applicable
    federal regulations and . . . manufacturing protocols approved by
    the FDA”; (5) distributed its implants “in violation of the terms of
    the IDE and applicable federal law”; (6) “negligently
    incorporat[ed] components and/or materials into its . . .
    [i]mplants that could not stand up to normal usage and/or [that]
    differed from those [that] were commercially reasonable and/or
    fail[ed] to use the components and/or materials approved by the
    FDA”; (7) “fail[ed] to exercise reasonable care in inspecting and
    6
    testing of the product”; (8) “fail[ed] to exercise reasonable care in
    its manufacturing, quality control, and quality assurance
    processes”; and (9) “was negligent in its recordkeeping and did
    not disclose manufacturing flaws.”
    In support of her failure-to-warn claims, Mize alleged
    that Mentor breached its duty to report to the FDA, as part of the
    IDE clinical tests and the six postapproval studies, “adverse
    events similar to the injuries [she] suffered” despite having
    “knowledge and possession of information” that its MemoryGel
    implants were dangerous. Mentor also did not ensure that the
    FDA-mandated studies were properly performed and did not
    ensure follow-up with enough study participants. “Accordingly,
    the information . . . the FDA [sought] regarding adverse events
    and device failures was never gathered.” Had it been gathered
    and reported, doctors would have seen and relayed it to Mize,
    who would have then had her implants removed.
    The demurrer
    Mentor demurred to the complaint. It asserted that
    Mize’s claims were preempted by federal law and insufficiently
    pled, and that Nguyen’s claim failed because it was derivative of
    his wife’s.
    The trial court agreed with Mentor. As to the
    manufacturing defect claims, the court found that they were
    impliedly preempted because they “hinge[d] entirely on conduct
    that allegedly violated federal law.” Even if they were not, the
    allegations that underlay the claims all preceded the 1998
    consent decree between Mentor and the FDA. But Mize did not
    allege that her implants were manufactured prior to the decree.
    And if they were manufactured after, the decree showed that
    Mentor promised to change any faulty manufacturing practices.
    7
    To the extent Mize based her claims on Mentor’s alleged
    noncompliance with IDE requirements, the complaint did not
    specify how that noncompliance occurred, that it occurred prior to
    her implant surgery, or how it “affected the manufacture of the
    device implanted.”
    As to the failure-to-warn claims, the trial court found
    them expressly preempted because Mize did not allege that
    Mentor’s failure to report adverse events violated any FDA
    requirement. Even if she did, to succeed on her claims Mize had
    to allege that “if Mentor had reported additional adverse
    incidents [after she received her implants in] 2000, and if the
    FDA had made such incidents public, and if [Mize’s] doctors had
    been aware of such reports, [the] doctors might have provided an
    earlier diagnosis leading to earlier surgery to remove the
    implants,” reducing Mize’s damages. The trial court found she
    did not do so.
    The trial court impliedly rejected Mize’s negligence
    per se claim since it was based on the same allegations as her
    other claims. The court rejected Nguyen’s loss-of-consortium
    claim as derivative of his wife’s. It sustained Mentor’s demurrer
    without leave to amend.
    DISCUSSION
    Standard of review
    “In reviewing the sufficiency of a complaint against a
    general demurrer, we are guided by long-settled rules.” 
    (Blank, supra
    , 39 Cal.3d at p. 318.) “‘We treat the demurrer as admitting
    all material facts properly [pled], but not contentions, deductions,
    or conclusions of fact or law.’” (Ibid.) “‘We also consider matters
    [that] may be judicially noticed.’” (Ibid.) “[W]e give the
    complaint a reasonable interpretation, reading it as a whole and
    8
    its parts in their context.” (Ibid.) Our fundamental task is to
    “determine whether the complaint states facts sufficient to
    constitute a cause of action.” (Ibid.)
    Preemption
    Federal law is the “supreme [l]aw of the [l]and.”
    (U.S. Const., art. VI, cl. 2.) State laws that conflict with federal
    laws are preempted. (Murphy v. National Collegiate Athletic
    Assn. (2018) __ U.S. __, __ [
    138 S. Ct. 1461
    , 1476].) Preemption
    can be express or implied. (English v. General Electric Co. (1990)
    
    496 U.S. 72
    , 78-79.) It is express if Congress defines “the extent
    to which its enactments preempt state law.” (Id. at p. 78.) It is
    implied if state law “regulates conduct in a field that Congress
    intended the [f]ederal [g]overnment to occupy exclusively” or if it
    “actually conflicts with federal law.” (Id. at p. 79.)
    The MDA expressly preempts any state requirement
    that: (1) “is different from, or in addition to, any requirement
    applicable under [the FDCA],” and (2) “relates to the safety or
    effectiveness of the device or to any other matter included in a
    requirement applicable to the device under [the FDCA].”
    (§ 360k(a).) The MDA “does not prevent a [s]tate from providing
    a remedy for claims premised on a violation of FDA regulations,”
    however, because “the state [requirements] in such a case
    ‘parallel,’ rather than add to, federal requirements.” 
    (Riegel, supra
    , 552 U.S. at p. 330.) A state requirement parallels a
    federal requirement if the two are “‘“‘generally equivalent.’”’”
    
    (Glennen, supra
    , 247 Cal.App.4th at p. 10.) But “[i]f state law
    liability could be found notwithstanding compliance with the
    federal requirements, those state law duties are not parallel to
    the federal requirements.” (Ibid.) Claims seeking to enforce
    those duties are expressly preempted. (Ibid.)
    9
    Alternatively, a plaintiff’s claim will be impliedly
    preempted if it conflicts with the MDA’s enforcement scheme.
    (Buckman Co. v. Plaintiffs’ Legal Committee (2001) 
    531 U.S. 341
    ,
    352 (Buckman).) Section 337(a) provides that “all . . . proceedings
    for the enforcement, or to restrain violations, of [the MDA] shall
    be by and in the name of the United States.” This provision
    prohibits claims that “seek[] to enforce an exclusively federal
    requirement that is not grounded in traditional state tort law.”
    
    (Glennen, supra
    , 247 Cal.App.4th at p. 11, italics added.) Thus, if
    an FDA requirement is “a critical element” of a plaintiff’s tort
    claim, the claim conflicts with the MDA’s enforcement scheme
    and is impliedly preempted. (Buckman, at pp. 352-353.)
    Together, express preemption under section 360k(a)
    and implied preemption under section 337(a) and Buckman
    create a “‘“‘narrow gap’ through which a state-law claim must fit
    to [survive] preemption.”’” 
    (Glennen, supra
    , 247 Cal.App.4th at p.
    11.) The claim must be based on “‘“conduct that violates the
    [MDA],”’” but the plaintiff cannot be “‘“suing because the conduct
    violates the [MDA].”’” (Id. at pp. 11-12, original italics.) Thus,
    “‘“to survive preemption, [a] claim[] ‘must be premised on conduct
    that both (1) violates the [MDA] and (2) would give rise to a
    recovery under state law even in the absence of the [MDA].’”’
    [Citation.]” (Id. at p. 12.)
    Manufacturing defect
    Mize first contends the trial court erred when it
    concluded that: (1) the MDA impliedly preempts her
    manufacturing defect claims, and (2) the complaint fails to link
    the alleged defects in her implants to her injuries. We agree.
    10
    1. Preemption
    Mize’s manufacturing defect claims are premised, at
    least in part, on Mentor’s alleged failure to comply with
    manufacturing requirements imposed by the FDA. But it does
    not follow that the claims “hinge entirely on conduct that
    allegedly violated federal law,” as the trial court concluded. Mize
    does not seek to enforce any exclusively federal requirement; her
    claims are predicated on violations of state tort law. (Cf. Jiminez
    v. Sears, Roebuck, & Co. (1971) 
    4 Cal. 3d 379
    , 384-387 [California
    recognizes negligence and strict liability claims of manufacturing
    defects].) That these tort theories “impose[] obligations identical
    to those imposed by the [FDA] . . . does not substantively
    transform [Mize’s] action into one seeking to enforce federal law.”
    (Farm Raised Salmon Cases (2008) 
    42 Cal. 4th 1077
    , 1095.) Her
    lawsuit would exist regardless of whether the FDA or some other
    federal or state agency imposed the obligations. (Id. at pp. 1095-
    1096.) There is thus no conflict with section 337(a), and no
    implied preemption under Buckman. (Ibid.; see, e.g., Mink v.
    Smith & Nephew, Inc. (11th Cir. 2017) 
    860 F.3d 1319
    , 1330
    [manufacturing defect claims not impliedly preempted]; Bass v.
    Stryker Corp. (5th Cir. 2012) 
    669 F.3d 501
    , 513-514 (Bass)
    [same]; Bausch v. Stryker Corp. (7th Cir. 2010) 
    630 F.3d 546
    , 556-
    558 (Bausch) [same].)
    
    Glennen, supra
    , 
    247 Cal. App. 4th 1
    , on which Mentor
    relies, is not to the contrary. In Glennen, the plaintiff’s claim was
    based on the defendant’s alleged failure to train physicians how
    to use its product, as the FDA required. (Id. at p. 20.) But “there
    is no state law duty that requires a medical device manufacturer
    to offer a physician training program.” (Ibid.) The claim thus
    “‘exist[ed] solely by virtue of [FDA] requirements’” and was
    11
    impliedly preempted. (Ibid.) Here, in contrast, Mentor had a tort
    duty, under California law, to manufacture its breast implants in
    compliance with FDA requirements. (Armstrong v. Optical
    Radiation Corp. (1996) 
    50 Cal. App. 4th 580
    , 595 (Armstrong).)
    Evraets v. Intermedics Intraocular, Inc. (1994) 
    29 Cal. App. 4th 779
    (Evraets) does not suggest there is no such duty,
    as Mentor asserts. That case involved claims based on
    inadequate testing, defective design, and failure to warn, not
    manufacturing defects. (Id. at p. 787.) “It is axiomatic that cases
    are not authority for propositions . . . not considered.” (California
    Building Industry Association v. State Water Resources Control
    Board (2018) 
    4 Cal. 5th 1032
    , 1043.) More significantly, Evraets
    predated the U.S. Supreme Court’s decision in Medtronic, Inc. v.
    Lohr (1996) 
    518 U.S. 470
    , 497-502 (Lohr), which held that the
    MDA does not preempt state-law claims based on manufacturing
    defects. Thus, to the extent Evraets suggested otherwise, it is no
    longer good law. 
    (Armstrong, supra
    , 50 Cal.App.4th at p. 596, fn.
    13.) Mize’s claims are not impliedly preempted.
    2. Causation
    “[U]nder either a negligence or strict liability theory
    of products liability, to recover from a manufacturer a plaintiff
    must prove that a defect caused [their] injury.” (Merrill v.
    Navegar, Inc. (2001) 
    26 Cal. 4th 465
    , 479.) This requires showing
    “some substantial link or nexus” between the alleged defect and
    the injury. (Saelzler v. Advanced Group 400 (2001) 
    25 Cal. 4th 763
    , 778.) At the pleading stage, the plaintiff need only allege “‘a
    causal connection’” between the two. 
    (Rannard, supra
    , 26 Cal.2d
    at p. 156.) “‘Ordinarily that is accomplished by implication from
    the juxtaposition of the allegations of wrongful conduct and
    harm.’” (Christensen v. Superior Court (1991) 
    54 Cal. 3d 868
    , 900
    12
    (Christensen).) It is only “‘where the pleaded facts of negligence
    and injury do not naturally give rise to an inference of causation
    [that] the plaintiff must plead specific facts affording an inference
    the one caused the others.’ [Citation.]” (Id. at pp. 900-901.)
    Mize sufficiently pled her manufacturing defect
    claims. She alleged that in the years leading up to her implant
    surgery Mentor failed to meet FDA-imposed manufacturing
    quality standards, destroyed evidence of its implants’ high
    rupture rates, sold contaminated implants, and failed to comply
    with FDA-mandated design and materials specifications. She
    alleged that she later suffered a number of ailments that
    subsided once her implants were removed. That juxtaposition
    naturally gives rise to an inference that Mentor’s alleged
    manufacturing defects caused her injuries. 
    (Christensen, supra
    ,
    54 Cal.3d at pp. 900-901.)
    The trial court improperly refused to make this
    inference. As part of the 1998 consent decree between Mentor
    and the FDA, Mentor promised to remedy its alleged violations,
    comply with federal law, and implement good manufacturing
    practices. To the court below, this promise broke any causal
    connection between Mentor’s manufacturing conduct and Mize’s
    defective implants. But a company’s promise to do something
    does not establish that it did so. The FDA’s 2003 nonopposition
    to the consent decree’s dissolution similarly does not defeat an
    inference of causation; it merely shows that the FDA believed
    that Mentor remedied the problems, not that it did.
    The trial court also faulted Mize for insufficiently
    pleading how Mentor failed to comply with IDE requirements or
    how that failure affected the manufacture of her implants. The
    court required too much of Mize at the pleading stage. Under
    13
    California law, a plaintiff may allege facts “in a conclusory
    fashion if their knowledge of the precise cause of injury is
    limited.” (Bockrath v. Aldrich Chemical Co., Inc. (1999) 
    21 Cal. 4th 71
    , 80 (Bockrath).) That is particularly true where, as
    here, the “‘defendant has superior knowledge of the facts.’” (Doe
    v. City of Los Angeles (2007) 
    42 Cal. 4th 531
    , 549-550.)
    “[I]n the context of Class III medical devices,” such as
    Mentor’s MemoryGel breast implants, “much of the critical
    information is kept confidential as a matter of federal law.”
    
    (Bausch, supra
    , 630 F.3d at p. 560.) “An injured patient,” like
    Mize, thus “cannot gain access to that information without
    discovery” (ibid.), and cannot “fairly be expected to provide a
    detailed statement of the specific bases for her claim” (id. at p.
    558). She should not be required to meet a pleading standard
    that identifies specific IDE requirements breached by Mentor
    based on information available only to Mentor and the FDA.
    (Coleman v. Medtronic, Inc. (2014) 
    223 Cal. App. 4th 413
    , 436
    (Coleman); see 
    Bockrath, supra
    , 21 Cal.4th at p. 82 [plaintiff
    could pursue claim despite lack of knowledge of specific cause of
    injury]; 
    Bass, supra
    , 669 F.3d at p. 511 [requiring allegations
    about confidential manufacturing processes “make[s] pleading a
    parallel [state] claim regarding defective manufacturing nearly
    impossible”].) The trial court erred when it sustained the
    demurrer to Mize’s manufacturing defect claims because she
    could not meet that standard.
    Failure to warn
    Mize next contends the trial court erred when it
    concluded that: (1) her failure-to-warn claims were expressly
    preempted, and (2) she did not sufficiently plead that Mentor’s
    14
    failure to report adverse events to the FDA caused her injuries.
    We again agree.
    1. Preemption
    Mize’s failure-to-warn claims are based on Mentor’s
    breach of its duty to report information about adverse events to
    the FDA. During clinical testing pursuant to an IDE, if a
    manufacturer evaluates unanticipated adverse events, it must
    “report the results of [that] evaluation to the FDA.” (21 C.F.R.
    § 812.150(b)(1).) If the manufacturer later wins premarket
    approval of its device, it must report to the FDA whenever the
    device “[m]ay have caused or contributed to a death or serious
    injury” or when it “[h]as malfunctioned and . . . would be likely to
    cause or contribute to a death or serious injury[] if the
    malfunction were to recur.” (21 C.F.R. § 803.50(a).) “A claim
    based on the failure to warn the FDA of adverse events is not
    preempted to the extent state tort law recognizes a parallel duty.”
    (Jacob v. Mentor Worldwide, LLC (C.D.Cal. 2019) 
    393 F. Supp. 3d 912
    , 925; see also Stengel v. Medtronic, Inc. (9th Cir. 2013) 
    704 F.3d 1224
    , 1233 (Stengel).) California law recognizes a
    manufacturer’s duty to warn the FDA of adverse events.
    
    (Coleman, supra
    , 223 Cal.App.4th at pp. 428-429.) Mize’s failure-
    to-warn claims are thus not expressly preempted. (Id. at p. 428.)
    Mentor counters that Mize’s claims do not survive
    preemption because the authority on which Coleman relied is no
    longer good law. In reaching its conclusion that the MDA does
    not preempt a failure-to-warn claim, the Coleman court relied
    largely on the Ninth Circuit’s decision in 
    Stengel, supra
    , 
    704 F.3d 1224
    . 
    (Coleman, supra
    , 223 Cal.App.4th at pp. 428-429.) That
    case concluded that: (1) a state-law tort claim based on a
    manufacturer’s failure to warn the FDA of problems with its
    15
    product is not preempted if state law recognizes a parallel duty,
    and (2) Arizona law recognizes such a duty. (Stengel, at pp. 1232-
    1233.) The Arizona Supreme Court subsequently rejected
    Stengel’s latter conclusion: “[E]stablished law does not recognize
    a claim merely for failing to provide something like adverse event
    reports . . . to a government agency.” (Conklin v. Medtronic, Inc.
    (Ariz. 2018) 
    431 P.3d 571
    , 579.)
    But that does not mean that Coleman is no longer
    good law in California. Conklin did not reject the Stengel court’s
    framework that a claim based on a manufacturer’s failure to
    warn of adverse events is not preempted if state law recognizes a
    parallel duty; it simply rejected the conclusion that Arizona law
    recognizes such a duty. Unlike Arizona, California does recognize
    a duty to report adverse events to the FDA. Coleman thus
    remains good law.
    The trial court employed a different rationale than
    Mentor, concluding that Mize’s failure-to-warn claims were
    expressly preempted because she did not show that Mentor’s
    failure to report adverse events violated any FDA requirement.
    In reaching this conclusion, the court adopted the reasoning of
    the federal district court in Ebrahimi v. Mentor Worldwide
    LLC (C.D.Cal., May 25, 2018, No. CV 16-7316-DMG (KSX)) 
    2018 WL 2448095
    . But Coleman was binding on the court below.
    (Auto Equity Sales, Inc. v. Superior Court (1962) 
    57 Cal. 2d 450
    ,
    455.) Ebrahimi was not. (Johnson v. American Standard,
    Inc. (2008) 
    43 Cal. 4th 56
    , 69.) Moreover, in her complaint Mize
    alleged that Mentor failed to report adverse events to the FDA, as
    it was required to do in both the IDE clinical tests and the
    postapproval studies. Because these allegations are based on a
    duty that is not “different from, or in addition to, any [FDA]
    16
    requirement,” Mize’s failure-to-warn claims are not expressly
    preempted.
    2. Causation
    To prevail on her failure-to-warn claims, Mize “‘will
    ultimately have to prove that if [Mentor] had properly reported
    the adverse events to the FDA as required under federal law,
    that information would have reached [her] doctors in time to
    prevent [her] injuries.’ [Citation.]” 
    (Coleman, supra
    , 223
    Cal.App.4th at pp. 429-430.) But at this stage, Mize need only
    allege “‘a causal connection’” between Mentor’s failure to report
    and her injuries. 
    (Rannard, supra
    , 26 Cal.2d at p. 156.) Here,
    Mize alleged that if Mentor complied with the reporting duties
    required in the IDE and postapproval studies, a fuller picture of
    the adverse events associated with its MemoryGel implants
    would have been available to the FDA, which would have in turn
    made that information available to Mize’s doctors via the
    MAUDE database. Mize’s doctors would then have
    communicated that information to Mize, who would have had her
    implants removed earlier. Assuming these allegations are true,
    they allege a sufficient causal connection between Mentor’s
    failure to report and Mize’s injuries.
    Mentor counters that Mize has not shown that
    information about adverse events would have reached her doctors
    in time to prevent her injuries. We conclude that her allegations
    are sufficient.
    First, while Mentor was required to report adverse
    events to the FDA, the evidence attached to its demurrer showed
    that for adverse events associated with implant ruptures it could
    submit spreadsheet reports that would not be included in the
    MAUDE database. But this ignores that Mentor was required to
    17
    provide individual medical device reports—which could be
    included in the database—whenever one of its implants
    contributed to a person’s death.
    Second, Mentor claims that even if it had submitted
    individual medical device reports, the FDA had discretion to not
    include those reports in the database. (21 C.F.R. § 803.9(a); see
    also Pinsonneault v. St. Jude Medical, Inc. (D. Minn. 2013) 
    953 F. Supp. 2d 1006
    , 1016 [adverse events not “automatically” made
    public].) But because the FDA regularly publishes such
    information in the database, it is reasonable to infer that it would
    have done so here. (See, e.g., Hughes v. Boston Scientific
    Corp. (5th Cir. 2011) 
    631 F.3d 762
    , 770, fn. 5; Rosen v. St. Jude
    Medical, Inc. (N.D.N.Y. 2014) 
    41 F. Supp. 3d 170
    , 187.)
    Finally, Mentor claims that even if it submitted
    individual medical device reports about implant ruptures, and
    even if the FDA would have exercised its discretion to include
    that information in the MAUDE database, there is no evidence
    that Mize’s doctors consulted the database when making
    decisions about her implants and their removal. But Mize alleges
    otherwise, and further claims that her doctors would have told
    her of the information in the database. It is reasonable to infer
    that they did review the database and would have provided that
    information to Mize. (See, e.g., Gravitt v. Mentor Worldwide,
    LLC (N.D.Ill. 2018) 
    289 F. Supp. 3d 877
    , 891.)
    “‘One of the dangers of winning on demurrer is that
    you are stuck, on appeal, with your opponent’s version of the
    facts.’” (Silguero v. Creteguard, Inc. (2010) 
    187 Cal. App. 4th 60
    ,
    64.) Here, Mize’s version of the facts is sufficiently pled to
    demonstrate a causal connection between Mentor’s reporting
    failures and her delayed decision to remove her implants.
    18
    Whether Mize can ultimately prove those facts is of no concern to
    us here. (Ibid.) A demurrer “‘may not be turned into a contested
    evidentiary hearing’” into the “‘truthfulness or proper
    interpretation’” of the evidence. (Ibid.) Because the trial court’s
    decision reflects such a consideration of the evidence, it
    erroneously sustained Mentor’s demurrer to Mize’s failure-to-
    warn claims.
    Negligence per se
    Mize contends the trial court erred when it dismissed
    her negligence per se claim since it is based on the same
    allegations as her manufacturing defect and failure-to-warm
    claims. She is correct.
    Under the doctrine of negligence per se, negligence
    will be presumed if: (1) a person violated a statute or regulation,
    (2) that violation injured another person or their property, (3) the
    injury was of a type the statute or regulation was designed to
    prevent, and (4) the person or property injured was of the class
    the statute or regulation was designed to protect. (Evid. Code,
    § 669, subd. (a).) Federal statutes, such as the FDCA or MDA,
    and federal regulations, such as those imposed by the FDA, may
    provide the applicable state standard of care, satisfying the first
    of these requirements. (DiRosa v. Showa Denko K.K. (1996) 
    44 Cal. App. 4th 799
    , 807; see 
    Coleman, supra
    , 223 Cal.App.4th at p.
    433; 
    Evraets, supra
    , 29 Cal.App.4th at pp. 791-792.) State-law
    tort claims that attempt to enforce these standards are not
    expressly preempted since the state requirements are identical to
    federal requirements. (Evraets, at p. 792; see § 360k(a) [only
    state requirements that are “different from, or in addition to”
    FDCA requirements are preempted].) Nor are such claims
    impliedly preempted when the plaintiff attempts to enforce state
    19
    requirements that parallel federal law.5 
    (Coleman, supra
    , 223
    Cal.App.4th at pp. 432-433.)
    Here, Mize alleged that Mentor violated the MDA
    and FDA-imposed requirements. She also alleged that Mentor’s
    manufacturing defects and its failure to properly report adverse
    events to the FDA caused her injuries. These injuries are clearly
    those the MDA and FDA regulations sought to prevent, and Mize
    is in the class the FDA sought to protect. She may therefore
    pursue her negligence per se claim. 
    (Coleman, supra
    , 223
    Cal.App.4th at p. 433.)
    Loss of consortium
    Finally, Nguyen contends the trial court erroneously
    sustained Mentor’s demurrer to his loss-of-consortium claim
    because it was derivate of his wife’s claims. He is correct.
    Because Mize sufficiently pled valid, non-preempted causes of
    action, Nguyen’s loss-of-consortium cause of action remains
    viable. 
    (Armstrong, supra
    , 50 Cal.App.4th at p. 597; see Hahn v.
    Mirda (2007) 
    147 Cal. App. 4th 740
    , 746 [loss of consortium claims
    “stands or falls” based on whether spouse suffered actionable
    injury].)
    5 We   disagree with the pre-Lohr and other non-California
    cases cited by Mentor that hold otherwise.
    20
    DISPOSITION
    The judgment is reversed, and the matter is
    remanded to the trial court with directions to enter an order
    overruling the demurrer to the third amended complaint. Mize
    and Nguyen shall recover their costs on appeal.
