    MEMORANDUM BY OTT, J.:                              FILED DECEMBER 26, 2019
    Christian L. Andrusis and Theresa A. Macurak, Co-Administrators of the
    Estate of Laura J. Andrusis, deceased (collectively, “Administrators”), appeal
    from the judgment entered August 17, 2018, in the Allegheny County Court
    of Common Pleas in favor of defendants, Robert Williams, M.D. (“Dr.
    Williams”), Allegheny General Hospital (“Hospital”), and Allegheny Radiology
    Associates (“Radiology”),1 following a jury trial in this medical malpractice
    action. Administrators raise three issues on appeal: (1) the trial court erred
    ____________________________________________
    1   We will refer to these three parties collectively as “Defendants.”
    J-A14012-19
    in admitting testimony concerning the decedent’s informed consent to the
    procedure; (2) the trial court erred in granting a compulsory nonsuit to
    additional defendant, MicroVention, Inc.; and (3) the trial court abused its
    discretion when it permitted Hospital and Dr. Williams to present cumulative
    expert testimony. For the reasons below, we affirm.
    The facts underlying Administrators’ medical malpractice claim are as
    follows. In November of 2005, during a procedure to repair a subarachnoid
    hemorrhage, the decedent’s neurosurgeon discovered she had an aneurysm
    on the superior tip of her basilar artery. See N.T., 11/28/2017-12/7/2017, at
    415-416. After recovering from the first procedure, the decedent was referred
    to Dr. Williams, an interventional radiologist, to treat the aneurysm. In June
    of 2006, Dr. Williams met with the decedent and her daughter, Theresa
    Macurak, to discuss a treatment plan. Because of the location of the aneurysm
    at the brain stem of the skull, Dr. Williams recommended the decedent
    undergo a cerebral angiogram and endovascular coiling of the aneurysm.2
    See id. at 418-420, 537-538
    On August 8, 2006, Dr. Williams performed the procedure on the
    decedent at Hospital. He chose to use a Boston Scientific SL-10 microcatheter,
    paired with a MircoVention HES-14 HydroCoil. See id. at 313-314, 580-581.
    ____________________________________________
    2The procedure involves inserting stents through the femoral artery, and
    maneuvering them through a microcatheter until reaching the aneurysm.
    Detachable coils are then guided though the microcatheter into the aneurysm,
    where they are designed to swell, fill the aneurysm, and promote clotting.
    See N.T., 11/28/2017-12/7/2017, at 532, 547-548, 579-580.
    -2-
    J-A14012-19
    Dr. Williams acknowledged the HES-14 coil was larger than what was
    recommended      for   use   with   the    SL-10   microcathether.       The   SL-10
    mircocatheter he used had a diameter of .0165 inches, and MicroVention
    recommended using a microcatheter with a diameter of .019 inches with the
    HES-14 coil. See id. at 653. Nevertheless, after consultation with another
    doctor, Dr. Williams paired the smaller microcatheter, which was more pliable
    than a larger microcatheter and would track better through the artery, with
    the larger coil because it would better fill the decedent’s aneurysm. See id.
    at 580-581, 587-589.
    Dr. Williams testified he placed the first coil in position within 90
    seconds. See id. at 586, 590. However, because the coil was in the dome of
    the aneurysm, rather than across the neck of the aneurysm, Dr. Williams had
    to reposition it. See id. at 587. He testified he was able to reposition the coil
    within three minutes.        See id. at 590, 659-660.              It merits mention
    MicroVention’s “Instructions for Use” (“IFU”) provides strict time frames for
    the repositioning of the coil once it is introduced into the microcatheter, and
    directs that the coil and microcatheter should be removed if they cannot be
    positioned and detached within the specified time frame. See id. at 316-317.
    Because Dr. Williams had paired the coil with a microcatheter that was not
    recommended, he        and another        doctor   chose   three    minutes as   the
    repositioning time. See id. at 589-590, 658. After placing the coil within the
    targeted time period, and confirming its position with an angiogram, Dr.
    Williams attempted to detach the coil from the pusher wire using a “V-grip”
    -3-
    J-A14012-19
    detachment device, so that he could insert another coil.     Id. at 591-592.
    However, as he explained, the coil would not detach from the pusher wire:
    I wasn’t getting the proper signal. I kept working with that. And
    I followed what the company suggested. Wipe it down. Try to
    work on the contact, and … I don’t remember all of the colors and
    lights, but it didn’t work.
    Id. at 591. Dr. Williams attempted to remove the coil with a second, and later
    third, “V-grip” device, which still did not work.3     See id. at 593-594.
    Ultimately, because he could not detach the coil from the pusher wire, Dr.
    Williams determined the coil had to be removed.      See id. at 595. As Dr.
    Williams attempted to pull the coil back into the microcatheter, he felt
    “friction.” Id. at 596. He hoped, however, the coil would “swell a little bit
    more [and] really lock into the microcatheter” so he could remove the entire
    device.    Id. at 597.      However, when he removed the microcatheter, he
    realized the stent had provided resistance against the coil, and the coil had
    broken off and remained “floating in the basilar artery.”   Id. at 599. The
    doctor then used a third stent to secure the coil in the vertebral artery, and
    abandoned the original procedure. See id. at 599-600. The decedent was
    ____________________________________________
    3 During this time, someone on Dr. Williams’ team also placed a call to their
    MicroVention representative for assistance.       See N.T., 11/28/2017-
    12/7/2017, at 593-594. MicroVention manufactured the Hydrocoil, as well as
    the pusher wire and “V-grip” used to detach the coil from the pusher wire.
    See Cross-Claim, 4/17/2013, at ¶ 26.          It did not manufacture the
    mircocatheter.

    transferred to the intensive care unit.          Later that evening, however, her
    aneurysm ruptured, and she died on August 11, 2006.
    Administrators initiated this medical malpractice action by writ of
    summons filed on August 5, 2008. In addition to Dr. Williams, Hospital and
    Radiology, Administrators also listed MicroVention as a defendant. Although
    MicroVention remained on the caption, Administrators’ complaint, filed on
    November 29, 2012, included no claims against the company.                Rather,
    Administrators alleged Dr. Williams, in his capacity as an agent or employee
    of Hospital and Radiology, committed medical malpractice with respect to his
    care of the decedent. See Complaint, 11/29/2012. After filing an answer and
    new matter, Hospital filed a cross-claim against MicroVention on April 17,
    2013, asserting the company was negligent in its design and/or manufacture
    of the HES-14 coil and detachment device. See Cross Claim, 4/17/2014.
    The case proceeded to a jury trial commencing on November 29, 2017.
    On December 7, 2017, the jury returned a verdict finding Dr. Williams was
    not negligent in his care of the decedent. Administrators filed timely post-trial
    motions, which the court denied on August 17, 2018. Dr. Williams filed a
    praecipe for entry of judgment on August 30, 2018, and this timely appeal
    followed.4
    ____________________________________________
    4 On September 5, 2018, the trial court ordered the Administrators to file a
    concise statement of errors complained of on appeal pursuant to Pa.R.A.P.
    1925(b). The Administrators complied with the court’s directive, and filed a
    concise statement on September 19, 2018.
    -5-
    J-A14012-19
    In their first issue on appeal, Administrators assert the trial court erred
    when it permitted testimony and evidence regarding the decedent’s “alleged
    consent to and understanding of the risks and complications of her …
    aneurysm coiling procedure.”         Administrators’ Brief at 34.    Relying upon
    Brady v. Urbas, 
    111 A.3d 1155
     (Pa. 2015), they maintain “evidence that a
    patient affirmatively consented to treatment after being informed of the risks
    of that treatment is generally irrelevant to a cause of action sounding in
    medical negligence.” Administrators’ Brief at 34-35. While they recognize
    some evidence regarding consent/risks may be relevant to establishing or
    refuting negligence, Administrators contend the testimony and evidence
    presented at trial herein should have been excluded.            See id. at 35-36.
    Because the evidence erroneously admitted in this case confused and misled
    the jurors, Administrators insist they should be granted a new trial. See id.
    at 42.
    When considering a claim challenging the trial court’s ruling on the
    admissibility of evidence, we are guided by the following:
    Generally, relevant evidence is admissible and irrelevant evidence
    is inadmissible. Evidence is relevant if it has “any tendency to
    make a fact [of consequence] more or less probable than it would
    be without the evidence.” Pa.R.E. 401. The threshold for
    relevance     is  low     given   the    liberal    “any tendency”
    prerequisite. Id. (emphasis added).        Relevant evidence “is
    admissible, except as otherwise provided by law.” Pa.R.E. 402.
    One such exception is that relevant evidence may be excluded “if
    its probative value is outweighed by a danger of one or more of
    the following: unfair prejudice, confusing the issues, misleading
    the jury, undue delay, wasting time, or needlessly presenting
    cumulative evidence.” Pa.R.E. 403.
    -6-
    J-A14012-19
    Decisions regarding the admissibility of evidence are vested in the
    sound discretion of the trial court, and, as such, are reviewed for
    an abuse of discretion. See Commonwealth v. Wright, 
    621 Pa. 446
    , 
    78 A.3d 1070
    , 1086 (2013). An abuse of discretion occurs
    where the trial court “reaches a conclusion that overrides or
    misapplies the law, or where the judgment exercised is manifestly
    unreasonable, or is the result of partiality, prejudice, bias, or ill
    will.” 
    Id. at 1080
    . To the degree the issue of whether the law
    has been misapplied involves a purely legal question, it is
    reviewed de novo. See Hoy v. Angelone, 
    554 Pa. 134
    , 
    720 A.2d 745
    , 750 (1998).
    Mitchell v. Shikora, 
    209 A.3d 307
    , 314 (Pa. 2019).                 Furthermore,
    “[a]n erroneous evidentiary ruling does not warrant a new trial unless it was
    ‘harmful or prejudicial to the complaining party.’” Flenke v. Huntington,
    
    111 A.3d 1197
    , 1200 (Pa. Super. 2015) (quotation omitted).
    In Brady, supra, the Pennsylvania Supreme Court held “in a trial on a
    [medical] malpractice complaint that only asserts negligence, and not lack of
    informed consent, evidence that a patient agreed to go forward with the
    operation in spite of the risks of which she was informed is irrelevant and
    should be excluded.” Brady, supra, 111 A.3d at at 1162-1163. Indeed, the
    Court explained “assent to treatment does not amount to consent to
    negligence, regardless of the enumerated risks and complications of which the
    patient was made aware.”       Id. at 1162.    Nevertheless, the Brady Court
    declined to adopt a “broad pronouncement” that such evidence is never
    admissible in a medical negligence trial. Id. Rather, the Court recognized
    some informed consent evidence “may be relevant to the question of
    negligence if, for example the standard of care requires the doctor discuss
    certain risks with the patient.” Id. at 1161. Under the particular facts of that
    -7-
    J-A14012-19
    case, however, the Court found the evidence permitted by the trial court,
    which specifically focused on the patient’s signed consent forms, was
    irrelevant “to the central question pertaining to whether the defendant’s
    actions conformed to the governing standard of care,” and affirmed the order
    granting a new trial. Id. at 1163.
    Recently, the Supreme Court revisited this issue in Mitchell, supra.
    Finding its decision in Brady had been misconstrued, the Mitchell Court
    opined:
    [O]ur Court in Brady spoke in terms of two discrete categories of
    evidence: (1) informed-consent evidence; and (2) risks and
    complications evidence. As to the first category, the Court plainly
    held that manifestations of a patient’s actual, affirmative consent
    to surgery, and the risks thereof, are irrelevant to the question of
    negligence. Brady, 111 A.3d at 1162. Thus, where a patient’s
    action is limited to medical negligence, and not a lack of informed
    consent, all evidence that a patient agreed to go forward with the
    operation, in spite of the risks of which she was informed, is
    irrelevant and should be excluded. Id. at 1162-63.
    However, the Court contrasted this with other types of evidence,
    such as evidence of risks and complications.               Indeed,
    the Brady Court specifically rejected the Superior Court’s per
    se rule that “all aspects of informed-consent information are
    always ‘irrelevant in a medical malpractice case.’” Id. at 1162.
    Rather, evidence of the risks and complications of a surgical
    procedure, “in the form of either testimony or a list of such risks
    as they appear on an informed-consent sheet” could be “relevant
    in establishing the standard of care.” Id.9
    _________
    9 While the Brady Court offered that a list of such risks “as
    they appear on an informed-consent sheet” may be relevant
    with respect to the standard of care, we interpret this to
    mean the generic offering of such risks, and not the
    informed-consent sheet itself. Id. at 1161. Indeed, to offer
    into evidence the informed-consent sheet itself would
    -8-
    J-A14012-19
    undermine the clear distinction made in Brady between
    informed consent evidence and risks and complications
    evidence, and such a proffer, absent special justification,
    would unnecessarily risk the very dangers regarding a jury
    receiving irrelevant informed consent evidence warned of
    in Brady.
    Mitchell, supra, 209 A.3d at 317. The Mitchell Court went on to explain the
    types of risks and complications evidence that may be admissible in a
    negligence only trial.
    Determining what constitutes the standard of care is complicated,
    involving considerations of anatomy and medical procedures, and
    attention to a procedure's risks and benefits. Further, a range of
    conduct may fall within the standard of care. While evidence that
    a specific injury is a known risk or complication does not
    definitively establish or disprove negligence, it is axiomatic that
    complications may arise even in the absence of negligence. We
    emphasize that “[t]he art of healing frequently calls for a
    balancing of risks and dangers to a patient. Consequently, if
    injury results from the course adopted, where no negligence or
    fault is present, liability should not be imposed upon the institution
    or agency actually seeking to assist the patient.” As a result,
    risks and complications evidence may clarify the applicable
    standard of care, and may be essential to provide, in this area, a
    complete picture of that standard, as well as whether such
    standard was breached.             Stated another way, risks and
    complications evidence may assist the jury in determining
    whether the harm suffered was more or less likely to be the result
    of negligence. Therefore, it may aid the jury in determining both
    the standard of care and whether the physician’s conduct deviated
    from the standard of care.
    Id. at 318 (internal citations omitted). Contrary to Brady, the Mitchell Court
    determined the evidence of potential risks and complications presented by the
    defendants at the medical negligence trial in that case was admissible. See
    id. at 323 (“[W]e find the trial court herein properly distinguished between
    -9-
    J-A14012-19
    informed-consent evidence, which it did not admit, and surgical risks and
    complications evidence, which it admitted.”).
    As for the case before us, prior to trial, Administrators filed a motion in
    limine seeking to preclude any testimony regarding the decedent’s informed
    consent to the risks of the surgery because the action alleged only medical
    negligence.5 During argument on the motion, Dr. Williams’ attorney stated
    he had “no problem with … agreeing to not presenting any testimony that the
    injury was the result of a risk or complication or suggesting that during the
    trial of the case.”     See N.T., 11/28/2017-12/7/2017, at 13.            Counsel for
    Hospital agreed, but noted that it would be “appropriate to discuss what the
    physicians discussed and generally what the risks and complications of the
    procedure could be.”        Id. at 14.         Following further discussion, the court
    granted Administrators’ motion “as worded” but recognized another ruling
    might be necessary at trial. Id. at 18. The order that was entered, stated
    the following:
    AND NOW this 28th day of November, 2017, upon consideration of
    the foregoing Motion in Limine to Exclude Testimony Regarding
    Risks and Complications, it is hereby ORDERED, ADJUDGED, and
    DECREED that said Motion is GRANTED and Defendants are
    prohibited from presenting testimony that [the decedent’s] injury
    was the result of a risk or complication of her procedure or
    suggesting the same at any point during the trial of this case.
    ____________________________________________
    5 We note Administrators’ motion in limine is included in the certified record.
    However, it is stamped as filed on February 22, 2018, after trial occurred.
    Nevertheless, none of the parties dispute the fact that Administrators did file
    a motion in limine before trial, and the trial court referred to the motion during
    pretrial arguments. See N.T., 11/28/2017-12/7/2017, at 10.
    - 10 -
    J-A14012-19
    Order, 11/28/2017. The court also handwrote on the order, “granted as per
    the record.” Id.
    Administrators contend Defendants violated the court’s order in the
    following manner. First, during his direct examination, Dr. Williams explicitly
    referred to the fact that the decedent signed an informed consent form:
    Q. And prior to the procedure taking place, did you again meet
    with the family or just see the patient in the operating room?
    [Dr. Williams:]   No.   I came into the holding area.      [The
    decedent] was there. Her daughter was there. I believe she was
    on her left side. I came in from her right. And I apologized. I
    was sorry that there was such a delay, and I explained what
    happened, and then we had her sign the informed consent
    and she was prepared. She understood the risks.
    N.T., 11/28/2017-12/7/2017, at 564 (emphasis supplied).         Administrators’
    counsel immediately objected, and requested a mistrial at sidebar. See id.
    at 564-565. Dr. Willams’ counsel apologized, and conceded the doctor “went
    way too far” in his answer, which was “not responsive to [counsel’s] question.”
    Id. at 565. He suggested the court instruct the jury that informed consent is
    not an issue in the case.   See id. After further discussion, the trial court
    denied the motion for mistrial, and gave the following cautionary instruction
    to the jury:
    Prior to the recess, actually prior to trial, okay, this Court
    ordered that informed consent was not to be discussed at this trial.
    Right before the recess, Dr. Williams inappropriately
    referenced informed consent and also the patient’s understanding
    of the procedural risks.
    These comments are to be stricken from the record and to
    be disregarded by the jury. Okay?
    - 11 -
    J-A14012-19
    Id. at 577.6
    The trial court found, however, that Dr. Williams’ comment did not
    mandate a new trial. We agree. The court acknowledged it was “concerned”
    Dr. Williams’ specific reference to informed consent was “improper and
    technically violated the [pretrial] order.” Trial Court Opinion, 12/7/2018, at
    15. However, the court concluded Dr. Williams’ answer was “not a substantive
    violation” of the court’s pretrial ruling because it was limited and did not
    include any specific testimony regarding “risks and complications or whether
    [the decedent] understood or fully consented to the procedure and actual risks
    and complications[.]”         Id. at 16.       The court found the answer was
    “unresponsive, unsolicited, and unexpected by everyone, … [and] did not
    mislead or confuse the jury as to medical negligence.” Id. Nevertheless, the
    court gave the jury a cautionary instruction, informing them that Dr. Williams
    “inappropriately referenced informed consent” despite a prior ruling that it
    was not to be discussed at trial. Id. at 17.
    We find no reason to disagree. While Dr. Williams’ unresponsive answer
    did violate the pretrial ruling, the trial court acted within its discretion when it
    declined to grant a mistrial.7         As the court explained, Dr. Williams’ brief
    ____________________________________________
    6 The court declined to instruct the jury that Dr. Williams violated an order of
    court, as suggested by Administrators. See id. at 571-576.
    7 See Bugosh v. Allen Refractories Co., 
    932 A.2d 901
    , 914–915 (Pa. Super.
    2007) (“Generally, the granting or refusal of a mistrial is a matter within the
    discretion of the trial judge, and his or her decision will not be overruled by
    an appellate court except for manifest, clear, or palpable error amounting to
    an abuse of discretion.”), appeal dismissed as improvidently granted, 
    971 A.2d 1228
     (Pa. 2009).
    - 12 -
    J-A14012-19
    reference to informed consent was unresponsive to the question asked, and
    the court issued a cautionary instruction, telling the jury Dr. Williams
    “inappropriately referenced informed consent” when the court had previously
    ordered that it was not to be discussed. Trial Court Opinion, 12/7/2018, at 17.
    We agree this instruction was sufficient to cure any prejudice from Dr.
    Williams’ remark.
    Further, we find the facts in this case distinguishable from those in
    Brady, supra, where the Supreme Court concluded a new trial was
    warranted.      In that case, the defendant doctor attempted to rebut the
    allegations of negligence by focusing on the consent forms signed by the
    plaintiff. The defendant doctor “questioned [the plaintiff] at length about her
    having signed the consent forms, elicited [his own] testimony on the topic,
    and made references to the fact of [the plaintiff’s] consent during []
    summation[.]” Brady, supra, 111 A.3d at 1163. Conversely, the trial court
    here found Dr. Williams’ comment did not constitute a flagrant or intentional
    violation of the court’s pretrial ruling. Significantly, Defendants did not discuss
    at length the signed consent forms, as in Brady, nor did Dr. Williams’ brief
    mention of the words “informed consent” have an instant prejudicial effect.8
    Accordingly, we agree the court’s cautionary instruction was sufficient to cure

    Second, Administrators point to Dr. Williams’ cross-examination of the
    decedent’s daughter, Theresa Macurak, when counsel asked if the doctor
    discussed “the risks of this particular procedure” with the decedent. Id. at
    439. Counsel for Administrators objected, arguing that the question violated
    the court’s pretrial “clear-cut ruling that the issues of risk and complications
    in this procedure were off limits[.]” Id. at 440. Dr. Williams’ counsel asserted,
    however, the question was in response to Administrators’ opening statement
    in which Administrators told the jury “Dr. Williams did not tell [the decedent]
    about certain things relating to her procedure.” Id. The court overruled the
    objection. Counsel’s follow-up question simply inquired of Macurak whether
    Dr. Williams “discuss[ed] with you about the risks of this procedure that your
    mom was about to undergo?” Id. at 442. Marcurak responded, “He did.” Id.
    There was no further testimony regarding specific risks or potential
    complications.
    With regard to this cross-examination, the trial court determined
    defense counsel’s questioning did not elicit any testimony regarding specific
    risks or complications of the procedure. See Trial Court Opinion, 12/7/2018,
    at 12.   Rather, the court found the questions were a proper response to
    Administrators’ “opening statement, where it was alleged that Dr. Williams
    - 14 -
    J-A14012-19
    failed to tell the [d]ecedent ‘a certain thing’ about the procedure[,]” as well
    as an inference from Macurak’s direct testimony that Dr. Williams told the
    decedent the procedure was “easy.”             Id. Therefore, the court concluded
    Defendants’ brief questions to Macurak was an appropriate response.9 Again,
    we agree.
    Our review of the record reveals that, during their opening statement,
    Administrators stated decedent’s aneurysm treated by Dr. Williams was “not
    dangerous or life-threatening,” and the decedent “readily agreed” to undergo
    the coiling procedure because “[i]t’s a much less invasive procedure” than
    surgery, with a “much lower recovery time.” N.T., 11/28/2017-12/7/2017, at
    181, 183. They argued that they did not fault him for recommending the
    procedure, but rather, “we do fault him, and we fault him enormously for what
    he did during the procedure; something he did that he never told [the
    decedent] he was going to do.” Id. at 184. Thereafter, during Macurak’s
    cross-examination, Dr. Williams’ counsel asked Macurak if Dr. Williams told
    the decedent it would be an “easy” procedure, to which she responded, “I
    don’t know if it was easy, but it was going to be much less invasive.” Id. at
    439. Counsel then asked, generally: “[A]mong the things that [Dr. Williams]
    discussed with you during that one-hour meeting … did he also discuss with
    ____________________________________________
    9The court opined, “[t]his [argument] is a clear example of [Administrators]
    wanting their cake and eating it too[.]” Trial Court Opinion, 12/7/2018, at 12.
    - 15 -
    J-A14012-19
    you and your mom the risks of this particular procedure?” Id. At that point,
    Administrators’ counsel objected. Following a sidebar discussion, the court
    overruled the objection, and counsel re-asked Macurak whether Dr. Williams
    discussed “the risks of this procedure that your mom was about to undergo?”
    Id. at 442. Macurak responded, “He did.” Id. When asked if she remembered
    any specifics about the “percentages of risk,” Macurak responded that she did
    not. Id. She did agree, however, that the decedent was impressed with the
    amount of time Dr. Williams spent explaining the procedure to her, believing
    he was “thorough.” Id. at 443. As evident from this excerpt, Defendants did
    not elicit any testimony regarding the specific risks or complications discussed
    with the decedent prior to the procedure.          Accordingly, the trial court
    concluded,
    [d]efense counsel’s questioning was general in nature and limited
    in scope and did not infer that the [d]ecedent’s injury or death
    was caused by any known risk or complication with the procedure.
    Defense counsel’s questioning did not elicit any testimony
    enumerating any specific risk or complications but rather tended
    to show that Dr. Williams had spent a significant amount of time
    explaining to the [d]ecedent and her family her medical options
    and the nature of the procedure without getting into informed
    consent and specific risks and complications.         This line of
    questioning counters [Administrators’] opening statement, where
    it was alleged that Dr. Williams failed to tell the [d]ecedent “a
    certain thing” about the procedure … [as well as] an inference that
    [Administrators’] counsel had made on direct that Dr. Williams
    had told [] Macurak and her mom that it was an “easy” procedure.
    Trial Court Opinion, 12/7/2018, at 12. We find no reason to disagree.
    Third, Administrators insist Defendants violated the ruling when they
    “presented to the jury” parts of the coiling device’s Instructions for Use (“IFU”)
    - 16 -
    J-A14012-19
    during the direct examination of Dr. Williams’ expert, Dr. Howard Dorne.
    Administrators’ Brief at 41.     The IFU included an area titled “Potential
    Complications.”   Dr. Williams’ counsel posed the following question to Dr.
    Dorne:
    Q. There’s an area down here called Potential Complications, and
    I don’t want to get into all of this stuff, but essentially, the
    MicroVention documents say, “The potential complications
    include, but are not limited to.” Then it goes on a list of things,
    including aneurysm rupture, et cetera, and it talks about difficult
    – premature or difficult coil detachment, right?
    A. Yes.
    Q. Okay. So this is what you were talking about before where
    you were aware that these things sometimes don’t detach or that
    there’s difficult coil detachment?
    A. Yes.
    Q. And that’s right in the IFU, right?
    A. Yes. It is.
    N.T., 11/28/2017-12/7/2017, at 785-786.       Administrators’ counsel did not
    immediately object to this line of questioning, but rather renewed his motion
    for a mistrial after Dr. Dorne’s direct examination. See id. at 803-804. The
    court overruled the objection, stating, “I need to hear the objection at the
    time it was done.” Id. at 804.
    We agree with the court’s ruling at the time of trial that Administrators’
    claim is waived because they failed to make a timely objection when the
    document was shown to the jury. “In order to preserve an issue for appellate
    review, an aggrieved party must make a timely and specific objection.” Allied
    Elec. Supply Co. v. Roberts, 
    797 A.2d 362
    , 365 (Pa. Super. 2002), appeal
    - 17 -
    J-A14012-19
    denied, 
    808 A.2d 568
     (Pa. 2002). Here, it was not until after the defense
    completed its direct examination of Dr. Dorne that Administrators objected to
    the fact Dr. Williams’ counsel “flashed in front of the jury the risk and
    complications of this procedure[,]” claiming it violated the motion in limine.
    N.T., 11/28/2017-12/7/2017, at 803.            The court overruled the objection
    stating, “frankly, I need to hear the objection at the time it was done.” Id. at
    804. We find no error in this ruling.
    Furthermore, the trial court also noted the “jury’s exposure to the IFU
    section ‘Potential Complications’ was minimal,” and counsel referred only to
    the possible complication of the coil’s failure to detach, “which was at the heart
    of the Defendants’ defense.” Trial Court Opinion, 12/7/2018, at 14. As our
    Supreme Court stated in Mitchell, “risks and complications evidence may
    clarify the applicable standard of care, and may be essential to provide, in this
    area, a complete picture of that standard, as well as whether such standard
    was breached.”    Mitchell, supra, 209 A.3d at 318.         Here, Administrators
    argued Dr. Williams acted negligently when he (1) used a combination of
    equipment not recommended by the manufacturer, and (2) employed a
    repositioning time that was not scientifically proven or accepted.           See
    Administrators’ Brief at 36.      In addition to attempting to rebut those
    allegations, Defendants asserted the real reason for the complication was the
    coil’s failure to detach, which, according to the IFU, was a potential
    complication. Accordingly, the trial court did not err in permitting this limited
    testimony, and Administrators’ first claim warrants no relief.
    - 18 -
    J-A14012-19
    Next, Administrators contend the trial court erred when it granted
    MicroVention’s motion for a compulsory nonsuit at the conclusion of trial, and
    refused to submit a strict liability “malfunction theory” claim to the jury. See
    Administrators’ Brief at 43.
    As noted supra, Administrators did not assert any claims against
    MicroVention in their complaint. However, Hospital filed a cross-claim against
    the company, contending its HydroCoil and delivery system were defectively
    designed and/or manufactured.       See Cross Claim, 4/17/2013, at ¶ 31.
    Counsel for both Dr. Williams and Hospital argued in their opening statements
    that the product’s failure to detach was the cause of the complication that
    occurred during the decedent’s coiling procedure, and not any actions taken
    or decisions made by Dr. Williams. See N.T., 11/28/2017-12/7/2017, at 240-
    245, 253-257. However, after Administrators presented their case-in-chief,
    Defendants informed the trial court they had entered into a confidential
    settlement agreement with MicroVention, and did not intend to present
    evidence against the company at trial. See id. at 480-481. Microvention, in
    turn, requested the court grant a compulsory nonsuit since Administrators
    presented no evidence of a product defect during their case-in-chief. See id.
    at 481. Administrators objected to the nonsuit, insisting they should receive
    “the benefit of [the Hosptial’s] joinder[,]” because they could “theoretically …
    establish a case against MicroVention during the cross-examination of Dr.
    Williams.” Id. at 482. Ultimately, the trial court agreed with Administrators
    that “a nonsuit at this time would be inappropriate.” Id. at 503. However,
    - 19 -
    J-A14012-19
    after Defendants presented their case-in-chief, MicroVention renewed its
    motion for a compulsory nonsuit. See id. at 1017. The court took the matter
    under advisement, and later granted that motion. See id. at 1042.
    Our review of a court ruling granting a compulsory nonsuit is well-
    established:
    A trial court may enter a compulsory nonsuit on any and all
    causes of action if, at the close of the plaintiff’s case against
    all defendants on liability, the court finds that the plaintiff
    has failed to establish a right to relief. Pa.R.C.P. No.
    230.1(a),      (c); see Commonwealth             v.     Janssen
    Pharmaceutica, Inc., 
    607 Pa. 406
    , 
    8 A.3d 267
    , 269 n.2
    (2010). Absent such finding, the trial court shall deny the
    application for a nonsuit.            On appeal, entry of
    a compulsory nonsuit is affirmed only if no liability exists
    based on the relevant facts and circumstances, with
    appellant receiving “the benefit of every reasonable
    inference and resolving all evidentiary conflicts in
    [appellant’s] favor.” Agnew v. Dupler, 
    553 Pa. 33
    , 
    717 A.2d 519
    , 523 (1998). The compulsory nonsuit is otherwise
    properly removed and the matter remanded for a new trial.

    618 Pa. 363
    , 
    57 A.3d 582
    , 595–96 (2012). The appellate court must review the
    evidence to determine whether the trial court abused its discretion
    or made an error of law. Barnes v. Alcoa, Inc., 
    145 A.3d 730
    ,
    735 (Pa. Super. 2016).
    Baird v. Smiley, 
    169 A.3d 120
    , 124 (Pa. Super. 2017).
    In the present case, Administrators argue the trial court erred in
    removing the strict liability, product defect claim from the jury because, while
    there was no direct evidence presented of a specific manufacturing defect in
    the coiling system, there was sufficient evidence to support a “malfunction
    theory” strict liability claim. Administrators’ Brief at 43.
    - 20 -
    J-A14012-19
    The Pennsylvania Supreme Court first adopted the malfunction theory
    in Rogers v. Johnson & Johnson, 
    565 A.2d 751
     (Pa. 1989).                     The
    malfunction theory allows a plaintiff to prove a product defect with
    circumstantial evidence, when the plaintiff “may not be able to prove the
    precise nature of the defect.” Id. at 754.
    [The malfunction theory] permits a plaintiff to prove a defect in a
    product with evidence of the occurrence of a malfunction and with
    evidence eliminating abnormal use or reasonable, secondary
    causes for the malfunction. It thereby relieves the plaintiff from
    demonstrating precisely the defect yet it permits the trier-of-fact
    to infer one existed from evidence of the malfunction, of the
    absence of abnormal use and of the absence of reasonable,
    secondary causes.
    Id. (internal citations omitted). Therefore, in order to present a prima facie
    case of a manufacturing defect pursuant to the malfunction theory, a plaintiff
    must establish: (1) “circumstantial evidence that the product had a defect,
    even though the defect cannot be identified[;]” and (2) “evidence eliminating
    abnormal use or reasonable, secondary causes” so that the jury can infer the
    defect caused the injury. Barnish v. KWI Bldg. Co., 
    980 A.2d 535
    , 541 (Pa.
    2009). The Supreme Court explained:
    By point of comparison, a plaintiff does not present a prima
    facie malfunction theory case if the plaintiff’s theory of the case
    includes facts indicating that the plaintiff was using the product in
    violation of the product directions and/or warnings. In such a
    case, no reasonable jury could infer that an unspecified defect
    caused a malfunction when the more likely explanation is the
    abnormal use. Similarly, if the plaintiff’s theory of the case
    includes another cause for the malfunction such as a improper
    maintenance or substantial wear and tear from regular use, a
    reasonable jury could not conclude that the product was defective
    at the time of delivery when facts presented by the plaintiff
    - 21 -
    J-A14012-19
    suggest a cause for the malfunction unrelated to the alleged,
    unspecified defect.
    Id. at 542.
    We will presume, for the sake of argument, there was sufficient
    circumstantial evidence of the coiling system’s malfunction to satisfy the first
    element of a malfunction theory claim.10 Dr. Williams himself testified the
    device “didn’t work” because the coil “didn’t detach,” and encouraged the
    decedent’s family to investigate MicroVention.           See N.T., 11/28/2017-
    12/7/2017, at 631-632, 635.           Macurak testified that Dr. Williams told the
    family “he was upset with the product, the trigger mechanism, and he did not
    ever want to use it again[.]” Id. at 425. Expert witness, Dr. Dorne, testified
    on direct examination that “these types of non detachments can and do occur
    even when the surgeon does everything correctly.”           Id. at 747.   He also
    acknowledged under cross-examination that he stated in his expert report,
    the “root cause from the failure of [the decedent’s] brain aneurysm coiling
    procedure was the catastrophic failure of detachment of the MicroVention
    HydroCoil system.” Id. at 817-818. Furthermore, Administrators’ expert, Dr.
    ____________________________________________
    10 We note the trial court concluded the evidence of the coil system’s failure
    to detach was not “legally sufficient evidence of a malfunction” because it was
    a rare, but foreseeable risk, of using the product. Trial Court Opinion,
    12/7/2018, at 21 (“The fact that the coil failed to detach is not evidence of a
    malfunction where non-detachment was a known possibility as outlined in the
    manufacturer[’]s IFU.”).
    - 22 -
    J-A14012-19
    Charles Kerber, acknowledged that “[f]ailure to detach is generally a product
    problem.”11 Id. at 372.
    Nevertheless, as the trial court explains in its opinion, even when
    plaintiffs present evidence of a product malfunction, they are still “required to
    provide evidence eliminating abnormal use or reasonable secondary causes
    for a malfunction” in order to present a prima facie case under the malfunction
    theory. Trial Court Opinion, 12/7/2018, at 21. This is where Administrators’
    claim fails. The court opined:
    The record is clear that the [Administrators’] original theory in
    their medical malpractice case was that Dr. Williams used the coil
    in an abnormal way. Specifically, [their] expert Dr. Kerber
    testified that Dr. Williams failed to follow the manufacturer’s
    instructions when he chose to use the incorrect micro catheter
    (sic) (SL-10) with the HES-14 HydroCoil. In addition, [the
    Administrators’] other theory of negligence was that Dr. Williams
    exceeded the scientifically proven and accepted repositioning time
    for the combination of the equipment used, including the
    HydroCoil. The evidence of other reasonable, secondary causes
    or abnormal use was clearly presented in the [Administrators’]
    medical malpractice cases and thus contradicts the establishment
    of a prima facie malfunction case.             Contrary to [the
    Administrators’ concise] statement, the [Administrators’] own
    proof of abnormal use or secondary causes, along with their lack
    of proof of malfunction or product defect, precluded the jury from
    considering this issue as a matter of law.
    Id. at 22.
    ____________________________________________
    11On direct examination, however, Dr. Kerber opined that the product at issue
    did not malfunction. After inspecting the coiling system, Dr. Kerber concluded
    “this coil detached” as it was designed to do. N.T., 11/28/2017-12/7/2017,
    at 339. However, he opined Dr. Williams had an “error of perception” which
    led to the “clinical misadventure.” Id. at 340. Dr. Kerber agreed it was “Dr.
    Williams[’] knowing violation of the standard of care that caused this
    misadventure and resulted in [the decedent’s] death[.]” Id.
    - 23 -
    J-A14012-19
    Administrators insist, however, the trial court erred in focusing solely on
    their case-in-chief. Rather, they emphasize “Defendants’ defense to [their]
    malpractice claim was that there was no misuse of the system at any time
    during the coiling procedure, and that the system was being operated exactly
    as anticipated and directed by the manufacturer.” Administrators’ Brief at 47.
    They maintain:
    If the jury believed the evidence presented by Dr. Williams, the
    jury would conclude that Dr. Williams was not negligent, rather,
    that the product malfunctioned. By so concluding the jury would
    have eliminated the secondary cause cited by the trial court.
    Id. at 48.    Moreover, Administrators argue that pursuant to Rogers, “a
    plaintiff is permitted to present to the jury a malfunction case and an
    alternative theory of negligence[.]” Id. (emphasis in original).
    We find Administrators have misconstrued the elements required to set
    forth a prima facie malfunction theory case. In Barnish, the Supreme Court
    made clear that in order to establish a malfunction theory claim, the plaintiff
    (here, Administrators) must present a case “free of abnormal use and
    secondary causes[.]” Barnish, supra, 980 A.2d at 542. See also Rogers,
    supra, 565 A.2d at 755 (“[W]e believe that so long as the plaintiffs presented
    a case-in-chief free of secondary causes which justified the inference of a
    defect in the product, the jury was free to accept their scenario.”) (footnote
    omitted). Indeed, the Court explained that if the plaintiff’s theory included
    facts that the plaintiff was using the product in violation of its directions, or
    the product malfunction could have been caused by improper maintenance,
    - 24 -
    J-A14012-19
    “no reasonable jury could infer that an unspecified defect caused a
    malfunction” when either (1) “the more likely explanation is the abnormal use”
    or (2) “the facts presented by the plaintiff suggest a cause for the malfunction
    unrelated to the alleged, unspecified defect.” Barnish, supra, 980 A.2d at
    542.
    In the present case, Administrators’ theory of the case not only included
    facts indicating the product was used in violation of its directions, their entire
    case was built upon the premise that the coiling system did not malfunction,
    but rather, Dr. Williams’ negligence led to the decedent’s death. See N.T.,
    11/28/2017-12/7/2017, at 339-340. Indeed, Administrators’ expert witness,
    Dr. Kerber, testified he inspected the coiling system at issue, and he was
    confident it did detach. See id. at 339. Rather, in his opinion, Dr. Williams
    violated the standard of care when he (1) combined the SL-10 microcatheter
    with the HES-14 HydroCoil;12 (2) estimated a repositioning time that was not
    scientifically proven; and (3) committed an “error of perception” when he
    believed the coil did not detach. See id. at 315-315, 317-318, 340. As such,
    because Administrators’ case was not “free of abnormal use and secondary
    causes,” they did not establish a prima facie malfunction theory case sufficient
    to proceed to the jury. Barnish, supra, 980 A.2d at 542. See also Schlier
    ____________________________________________
    12 Dr. Kerber testified: “I think the surgeon picked the wrong device and an
    incompatible device and got into trouble and couldn’t get out of trouble, and
    that led to the death. It’s … really that simple.” N.T., 11/28/2017-12/7/2017,
    at 305.

    v. Milwaukee Elec. Tool Corp., 
    835 F. Supp. 839
     (E.D. Pa. 1993) (finding
    plaintiff failed to establish prima facie case of product malfunction where
    “[b]ased on plaintiff’s own evidence, there is at least one secondary cause
    which could account for the accident[,]” that is, plaintiff noticed the saw at
    issue was dirty and the blade was not new).13
    Administrators insist, however, that their choice to pursue a malpractice
    claim against Dr. Williams did not preclude them from also arguing a
    malfunction theory claim to the jury. See Administrators’ Brief at 48. In fact,
    they contend this “exact dichotomy of competing product liability and medical
    malpractice theories” was addressed, and approved of, by the Court in
    Rogers. 
    Id.
     Indeed, the Rogers Court noted the Superior Court, in its earlier
    opinion, had implied “a plaintiff who has presented a malfunction case will
    always be precluded from proceeding upon an alternative theory of
    negligence.”     Rogers, supra, 565 A.2d at 755.          Disagreeing with this
    contention, the Court stated:
    It is altogether possible that a plaintiff’s injuries could be caused
    jointly by a defective product and also by third party negligence
    so long as the negligence does not constitute a supervening cause
    of the malfunction. “Given the occurrence of a malfunction, the
    [alleged] negligence assumes legal significance only if it was a
    superseding cause.... Questions of proximate causation should
    normally be left to the finder of fact.”

    important to consider it in the context of that case. In Rogers, the plaintiff
    received severe burns on his leg following the application of a plaster splint to
    immobilize a broken leg. See id. at 752. He initiated a claim against Johnson
    & Johnson, the manufacturer of the plaster splint, as well as the hospital where
    he had the procedure.      At trial, the plaintiff “presented expert testimony
    eliminating medical malpractice as the cause of the burns,” while Johnson &
    Johnson presented expert testimony “indicating that the medical malpractice
    of the doctors had caused the splint to overheat[.]”      Id. at 753 (footnote
    omitted).   The jury returned a verdict for the plaintiff on the malfunction
    theory claim. The Superior Court reversed on appeal, holding that because
    Johnson & Johnson presented sufficient evidence of the doctor’s negligence,
    the malfunction theory should not have been submitted to the jury because
    the plaintiff did not eliminate all reasonable, secondary causes for the
    malfunction.   See id.    As noted above, the Supreme Court reversed the
    Superior Court’s ruling, holding:
    The Superior Court erred because it considered incompatible the
    plaintiffs’ evidence of malfunction in light of the defendant,
    Johnson & Johnson’s, evidence of a reasonable secondary cause.
    It rendered impossible the ability of the plaintiffs to negate
    secondary causes suggested by Johnson & Johnson’s evidence and
    essentially required a directed verdict in favor of Johnson &
    Johnson. Contrarily, we believe that so long as the plaintiffs
    presented a case-in-chief free of secondary causes which justified
    the inference of a defect in the product, the jury was free to accept
    their scenario.

    Rogers, supra, 565 A.2d at 755 (footnote omitted).
    In   the   present   case,   however,    the   plaintiffs   (Administrators)
    proceeded only on a claim of medical malpractice, and attempted to “back
    door” a malfunction theory claim through the Defendants’ case-in-chief. This
    is certainly not the same situation as in Rogers, where the “alternative theory
    of negligence” was presented by the defendant. Id. at 755. Indeed, in a
    footnote, the Rogers Court explained:
    In this instance, for example, if the jury had chosen to believe
    Johnson & Johnson’s evidence that [the doctor’s] failure to heed
    [the plaintiff’s] complaints regarding a sensation of warmth
    constituted negligence such negligence would not supervene the
    cause of [the plaintiff’s] injuries, namely, the defective material of
    which the splint was made.
    Id. at 755 n.7.    Our research has uncovered no cases in which a plaintiff
    attempted to establish a malfunction theory case through the defendants’
    case-in-chief, while pursuing only an alternative theory of liability in his or
    her case-in-chief. Indeed, the malfunction theory allows the jury to “infer the
    existence of a defect from the fact of a malfunction.” Barnish, supra, 980
    A.2d at 541. However, as the Supreme Court explained in Barnish, if the
    plaintiff presents evidence that the product was used “in violation of the
    product directions and/or warnings” or “the plaintiff’s theory of the case
    includes another cause for the malfunction,” a reasonable jury could not “infer
    that an unspecified defect caused a malfunction when the more likely
    explanation is the abnormal use” or other cause. Id. Here, Administrators’
    theory of case was that Dr. Williams’ pairing of the SL-10 microcatheter with
    - 28 -
    J-A14012-19
    the HES-14 HydroCoil, as well as his estimated repositioning time frame,
    caused the complication which led to the decedent’s death. Accordingly, we
    find no error in the trial court’s decision to grant MicroVention a compulsory
    nonsuit at the conclusion of trial.14
    In their third, and final, issue, Administrators contend they are entitled
    to a new trial because the trial court erroneously permitted Defendants to
    present cumulative expert testimony. See Administrators’ Brief at 50. Prior
    to trial, Administrators sought a motion in limine to preclude Hospital and Dr.
    Williams from presenting separate expert witnesses on the relevant standard
    ____________________________________________
    14 In her Concurring and Dissenting Memorandum, Judge Kunselman asserts
    the Supreme Court’s decision in Rogers, supra, is controlling, and our
    attempt to distinguish it on its facts is erroneous. See Concurring and
    Dissenting Memorandum, at 6-8.            Indeed, Judge Kunselman sees no
    difference as to whether the plaintiff presents the malfunction theory or
    negligence theory; accordingly, so long as the party that presents the
    malfunction theory is free of secondary causes, “the claim of product
    malfunction should have gone to the jury.” Id. at 6. We disagree. The
    malfunction theory of product liability is “reminiscent of the logic of a res ipsa
    loquitur case,” and may be pursued only when the plaintiff eliminates all
    other causes for the injury.       Barnish, supra, 980 A.2d at 541 (“By
    demonstrating the absence of other potential causes for the malfunction, the
    plaintiff allows the jury to infer the existence of defect from the fact of a
    malfunction.”). Although Judge Kunselman believes which party pursues the
    theory is irrelevant, we find the language of the case law clear. Moreover,
    while the Rogers Court did not specifically state the “plaintiff’s ability to
    recover under these alternative theories of liability was limited only to cases
    where the plaintiff filed the products liability claim,” see Concurring and
    Dissenting Memorandum, at 8, we decline to expand application of the limited
    malfunction theory to include the facts in this case, where the plaintiff’s expert
    opined the product did not malfunction.

    of care.15 See N.T., 11/28/2017-12/7/2017, at 19. Hospital asserted that,
    because they are separate parties, they “should have a right to an expert of
    their choosing.”     Id. at 20.     The court agreed, and denied Administrators’
    motion.
    On appeal, Administrators argue the court should not have allowed both
    Hospital and Dr. Williams to present separate expert witness testimony at trial
    because they agreed to present a joint defense. See Administrators’ Brief at
    50. Administrators contend both experts - Dr. Howard Dorne for Dr. Williams
    and Dr. Alexander Coon for Hospital -
    reviewed the same set of documents and records and … arrived at
    the same conclusions (i.e. [Dr.] Williams was not negligent and
    met the applicable standard of care at all times during the course
    of the coiling procedure he performed on [the decedent] and [Dr.]
    Williams demonstrated proper neuro-interventional techniques
    and judgment during the entire course of the procedure).
    Id.   While Admininstrators acknolwedge Dr. Williams and Hospital were
    separate parties, they insist that, because there were no independent
    allegations against Hospital,16 “any expert testimony offered by the Hospital
    was in defense of [Dr.] Williams and was duplicative, cumulative, and
    prejudicial.” Id. at 51. Furthermore, they emphasize they were prejudiced

    15While a written motion in limine is not included in the certified record, the
    parties discussed this motion during pretrial arguments.            See N.T.,

    by the court’s ruling because counsel for both Dr. Williams and Hospital
    implied during their closing arguments that their three experts (which included
    Dr. Williams himself) “must be given greater weight than the sparse testimony
    presented by [Administrators’] one single witness.” Id. at 53. Accordingly,
    Administrators argue the court erred in failing to award them a new trial.
    As noted supra, “[d]ecisions regarding the admissibility of evidence are
    vested in the sound discretion of the trial court, and, as such, are reviewed
    for an abuse of discretion.” Mitchell, supra, 209 A.3d at 314. Pursuant to
    Pennsylvania Rule of Evidence 403, a trial court “may exclude relevant
    evidence if its probative value is outweighed by a danger of one or more of
    the following: unfair prejudice, confusing the issues, misleading the jury,
    undue delay, wasting time, or needlessly presenting cumulative evidence.”
    Pa.R.E. 403. Cumulative evidence has been defined as,
    “additional evidence of the same character as existing evidence
    and that supports a fact established by the existing evidence.” …
    Evidence that bolsters, or strengthens, existing evidence is
    not cumulative evidence, but rather is corroborative evidence.

    104 A.3d 5
     (Pa. 2014).
    In Klein, 
    supra,
     a panel of this Court found no error when a trial court
    permitted the defendants to present “three different expert witnesses on
    causation” because, while the experts “ultimately reached the same
    - 31 -
    J-A14012-19
    conclusion, … they approached the issue from different clinical perspectives.”
    
    Id.
     at 501 n.7.     Similarly, in Whitaker v. Frankford Hosp. of City of
    Philadelphia, 
    984 A.2d 512
     (Pa. Super. 2009), a panel of this Court found
    the trial court did not abuse its discretion when it permitted the plaintiffs to
    present two expert witnesses who each “touched briefly upon the subject
    matter that was thoroughly covered by the other expert witness.” 
    Id.
     at 522-
    523.    The panel noted “[e]ach expert witness clearly and unequivocally
    established the necessary component of liability in his area of expertise[,]”
    and the “slightly cumulative nature of the intersecting testimony was not so
    harmful” that it required a new trial. 
    Id. at 522-523
    .
    In the present case, the trial court defended its ruling by explaining,
    “while both experts did cover some of the same subject matter, they did so
    from entirely different perspectives.” Trial Court Opinion, 12/7/2018, at 23.
    The court opined:
    Dr. Dorne[’s] and Dr. Coon’s testimony is not cumulative as they
    were from different clinical backgrounds and thus testified from
    different perspectives. Dr. Dorne was verified as an expert as an
    interventional and neurointerventional radiologist. He was board
    certified in that field. Dr. Coon on the other hand testified as an
    expert in endovascular neurosurgery. He is board certified in that
    field and acts as the director of Endovascular Surgery at Johns
    Hopkins. As such, while the doctors may have provided some
    overlapping testimony, they testified from different expertise,
    much like the doctors in the Klein case.
    While this Court does recognize that some of the testimony
    by both Dr. Dorne and Dr. Coon was duplicative, they also testified
    separately regarding a number of items. Dr. Dorne defined the
    standard of care and noted that it does not require the physician
    to build in extra time during a procedure for the possibility of non-
    detachment. Furthermore, Dr. Dorne testified that Dr. Williams
    - 32 -
    J-A14012-19
    appropriately reduced the reposition time for the Hydro coil from
    five to three minutes in [d]ecedent’s procedure. Dr. Coon did not
    opine specifically on those two points.
    Dr. Coon also testified regarding a different subject matter
    than Dr. Dorne. Dr. Coon provided testimony regarding the
    general process of placing a catheter through the stents and into
    the aneurysm called “sequential stenting”. Additionally, Dr. Coon
    discussed the post-operative notes as well as the location of
    [d]ecedents’s second aneur[y]sm, both topics not covered by Dr.
    Dorne.
    As such, this Court finds that it did not err in permitting the
    testimony of both Dr. Dorne and Dr. Coon. In previously denying
    [Administrators’]    Motion in Limine          and now         denying
    [Administrators’] request for Post-trial relief, this Court finds their
    testimony non-cumulative. The doctors were called by separate
    parties, who had separate interests and liability in this case.
    Furthermore, while the Court notes that some of the testimony
    provided by Dr. Dorne and Dr. Coon covered the same subject
    matter, the case law in Pennsylvania allows that, and scrutiny of
    each of their testimony and qualifications shows that they testified
    as doctors of different specialties, and covered certain topics
    where the other did not. Thus it was proper for this Court to allow
    it.
    Id. at 24-25 (record citations omitted).
    Our review of the record reveals no basis upon which to disagree with
    the trial court. Although we recognize Hospital’s liability was only derivative
    of Dr. Williams’ liability, as separate parties with separate counsel, they should
    be permitted to choose their own experts. None of the statutory or case law
    cited by Administrators contradict that principle. Nevertheless, we recognize
    a trial court may exclude evidence that is cumulative. Here, however, as the
    court opined, each expert testified regarding a topic that was not addressed
    by the other expert. Accordingly, no relief is warranted, and we rest on the
    court’s well-reasoned basis.

    J-A14012-19
    Accordingly, because we conclude Administrators are entitled to no relief
    on the claims raised in this appeal, we affirm the judgment entered in favor
    of Defendants.
