6 Plaintiffs, ORDER
7 v.
8 JOHNSON & JOHNSON; ETHICON, INC.; and ETHICON LLC, 9 Defendants. 10 Presently before the Court is Defendant’s Motion to Limit Opinions of Daniel Elliott, M.D. 11 (#196). Plaintiffs responded in opposition (#206) and Plaintiffs replied (#219). 12 I. Factual and Procedural Background 13 This is a products liability action involving two prescription medical devices– Prolift and 14 TVT. On July 23, 2010, at St. Rose Dominican Hospital in Las Vegas, Nevada, Dr. Gregory 15 Hsieh implanted a Prolift device for Plaintiff Tamara Carter’s (“Mrs. Carter”) posterior pelvic 16 prolapse and a TVT mid-urethral sling for Mrs. Carter’s stress urinary incontinence (“SUI”). 17 Mrs. Carter alleges that these medical devices caused her injuries, and that Defendants are liable 18 under claims of strict liability for failure to warn and for design defect. Her husband, Plaintiff 19 David Carter (“Mr. Carter”) raises a loss of consortium claim. Additionally, Plaintiffs claim that 20 Defendants’ conduct was malicious, oppressive, willful, wanton, reckless, and grossly negligent. 21 Defendants (“Ethicon”) deny Plaintiffs’ allegations and assert that Prolift and TVT were state of 22 the art at the time of implant, that Mrs. Carter’s alleged injuries pre-dated her surgery, that Mrs. 23 Carter assumed the risks, and that Mrs. Carter’s own actions contributed to her injuries. 24 Dr. Daniel Elliott specializes in treating pelvic organ prolapse (“POP”) and urinary 25 incontinence. Plaintiffs have asked Dr. Elliott to provide opinions regarding the subject of female 26 stress urinary incontinence (“SUI”), POP, the actions of Ethicon, and specifically, the 27 characteristics of Ethicon’s products, Prolift and TVT, that make them defective. Defendants 28 1 have objected to the testimony and argue that he cannot provide reliable, trustworthy, or 2 admissible testimony about these topics. 3 II. Analysis 4 a. Legal Standard 5 Fed. R. Evid. 702 permits a “witness who is qualified as an expert by knowledge, skill, 6 experience, training, or education [to] testify in the form of an opinion or otherwise if: (a) the 7 expert’s scientific, technical, or other specialized knowledge will help the trier of fact to 8 understand the evidence or to determine a fact in issue; (b) the testimony is based on sufficient 9 facts or data; (c) the testimony is the product of reliable principles and methods; and (d) the 10 expert has reliably applied the principles and methods to the facts of the case.” The Supreme 11 Court gave expanded direction on Rule 702 in Daubert v. Merrell Dow Pharmaceuticals, Inc., 12 509 U.S. 579 (1993). In Daubert, the Court held that Rule 702 imposed “a special obligation 13 upon a trial judge to ‘ensure that any and all scientific testimony… is not only relevant, but 14 reliable.’” See Kumho Tire Co. v. Carmichael, 526 U.S. 137 (1999). The Court expanded this 15 gatekeeping obligation to all expert testimony. Id. at 147. Daubert “established that, faced with a 16 proffer of expert scientific testimony, the trial judge, in making the initial determination whether 17 to admit the evidence, must determine whether the expert’s testimony reflects (1) “scientific 18 knowledge,” and (2) will assist the trier of fact to understand or determine a material fact at 19 issue.” Daubert, 509 U.S. at 592. The “focus must be solely on principles and methodology, not 20 on the conclusions that they generate.” Id. at 595. 21 The Ninth Circuit has emphasized that “Rule 702 is applied consistent with the liberal thrust 22 of the Federal Rules and their general approach of relaxing the traditional barrier to opinion 23 testimony.” Jinro Am. Inc. v. Secure Investments, Inc., 266 F.3d 993, 1004 (9th Cir. 2001). “An 24 expert witness–unlike other witnesses–is permitted wide latitude to offer opinions, including 25 those that are not based on firsthand knowledge or observation, so long as the expert’s opinion 26 [has] a reliable basis in the knowledge and experience of his discipline.” Id. (citations and 27 quotation marks omitted). 28 In Daubert, the Court also clarified that parties should not be “overly pessimistic about the 1 capabilities of the jury and of the adversary system generally.” Daubert, 509 U.S. at 596. 2 “Vigorous cross-examination, presentation of contrary evidence, and careful instruction on the 3 burden of proof are the traditional and appropriate means of attacking shaky but admissible 4 evidence.” Id. “The role of the Court is not to determine ‘the correctness of the expert’s 5 conclusions but the soundness of his methodology.’” Great W. Air, LLC v. Cirrus Design 6 Corporation, No. 2:16-CV-02656-JAD-EJY, 2019 WL 6529046, *3 (D. Nev. 2019). “The judge 7 is supposed to screen the jury from unreliable nonsense opinions… [t]he district court is not 8 tasked with deciding whether the expert is right or wrong, just whether his testimony has 9 substance such that it would be helpful to a jury.” Id. at 4. 10 b. Dr. Daniel Elliot’s Testimony 11 i. Dr. Elliot’s Opinions about Prolift and TVT Based On His Prior 12 Publication 13 The Court finds that Dr. Elliott’s opinions about Prolift and TVT mesh used for treating SUI 14 and POP in women are admissible because they do not conflict with his previous publication. 15 Defendant argues that Dr. Elliott published literature in 2019 expressing that high-quality 16 evidence exists to support the idea that synthetic midurethral slings achieve excellent short-term 17 outcomes, and that the ideal mesh pore size is large. (#196, at 4–5). Defendant asserts that Dr. 18 Elliott testifies now, in this case, that polypropylene mesh should never be used to treat an SUI 19 and that all synthetic midurethral mesh slings are unsafe. Id. Plaintiffs argue in response that the 20 statements Ethicon points to in Dr. Elliott’s 2019 publication do not contradict his position on the 21 safety of mesh devices, and even if found contradictory, the adequate procedure is cross- 22 examination. (#206, at 8–10). 23 The 2019 publication does state that there is quality evidence indicating excellent short-term 24 outcomes and long-term efficacy. (#196-4, at 7). But the article also has a section called 25 “[s]ituations to avoid synthetic midurethral sling placement” and explains that there “are 26 contraindications to placement of urethral mesh, including patients undergoing… concomitant 27 SUI surgery.” Id. It also says that “the recent AUA guideline notes surgeons should consider 28 avoiding mesh placement in patients at risk for poor wound healing” and that in those cases, 1 there are other options surgeons can use such as Burch retropubic colposuspension. Id. In Dr. 2 Elliott’s expert report, he says that the mesh used in the TVT device “should not be used in the 3 pelvic floor because the risks of the device far outweigh the benefits of the device.” (196-1, at 4 13). It seems that Dr. Elliott acknowledges that mesh surgeries can be efficacious, but also that 5 there are risks associated with mesh surgeries under certain conditions. For example, in his report 6 Dr. Elliott states that “the TVT device should not be implanted into the human body for use in 7 the treatment of SUI” which is consistent with the publication where he states that “there are 8 contraindications to placement of urethral mesh” for SUI surgery. (Id. at 27). Dr.

Air, LLC v. Cirrus Design 6 Corporation, No. 2:16-CV-02656-JAD-EJY, 2019 WL 6529046, *3 (D. Nev. 2019). “The judge 7 is supposed to screen the jury from unreliable nonsense opinions… [t]he district court is not 8 tasked with deciding whether the expert is right or wrong, just whether his testimony has 9 substance such that it would be helpful to a jury.” Id. at 4. 10 b. Dr. Daniel Elliot’s Testimony 11 i. Dr. Elliot’s Opinions about Prolift and TVT Based On His Prior 12 Publication 13 The Court finds that Dr. Elliott’s opinions about Prolift and TVT mesh used for treating SUI 14 and POP in women are admissible because they do not conflict with his previous publication. 15 Defendant argues that Dr. Elliott published literature in 2019 expressing that high-quality 16 evidence exists to support the idea that synthetic midurethral slings achieve excellent short-term 17 outcomes, and that the ideal mesh pore size is large. (#196, at 4–5). Defendant asserts that Dr. 18 Elliott testifies now, in this case, that polypropylene mesh should never be used to treat an SUI 19 and that all synthetic midurethral mesh slings are unsafe. Id. Plaintiffs argue in response that the 20 statements Ethicon points to in Dr. Elliott’s 2019 publication do not contradict his position on the 21 safety of mesh devices, and even if found contradictory, the adequate procedure is cross- 22 examination. (#206, at 8–10). 23 The 2019 publication does state that there is quality evidence indicating excellent short-term 24 outcomes and long-term efficacy. (#196-4, at 7). But the article also has a section called 25 “[s]ituations to avoid synthetic midurethral sling placement” and explains that there “are 26 contraindications to placement of urethral mesh, including patients undergoing… concomitant 27 SUI surgery.” Id. It also says that “the recent AUA guideline notes surgeons should consider 28 avoiding mesh placement in patients at risk for poor wound healing” and that in those cases, 1 there are other options surgeons can use such as Burch retropubic colposuspension. Id. In Dr. 2 Elliott’s expert report, he says that the mesh used in the TVT device “should not be used in the 3 pelvic floor because the risks of the device far outweigh the benefits of the device.” (196-1, at 4 13). It seems that Dr. Elliott acknowledges that mesh surgeries can be efficacious, but also that 5 there are risks associated with mesh surgeries under certain conditions. For example, in his report 6 Dr. Elliott states that “the TVT device should not be implanted into the human body for use in 7 the treatment of SUI” which is consistent with the publication where he states that “there are 8 contraindications to placement of urethral mesh” for SUI surgery. (Id. at 27). Dr. Elliott’s 9 deposition also states that he believes all the mesh slings currently available in the market are 10 unsafe and implies that his concern is about long-term follow-up satisfaction despite the many 11 studies showing current satisfaction. (#196-8, at 10). Therefore, the Court rejects Defendant’s 12 argument that Dr. Elliott’s current testimony contradicts his publication and will allow direct and 13 cross-examination to flesh out the nuances of his opinion. Dr. Elliott may be wrong about mesh 14 being hazardous, but that is not for the Court to decide. See Daubert, 509 U.S. at 595. 15 ii. Dr. Elliott’s Opinions About Non-Synthetic Mesh Procedures as Safer 16 Alternatives Than Prolift and TVT 17 1. Relevancy 18 Ethicon argues that Dr. Elliott’s opinions about autologous slings and Burch colposuspension 19 being safer alternatives than TVT for the surgical treatment of SUI, and his opinions that native 20 tissue repairs like sacrocolpopexy and colporrhaphy are safer alternatives to Prolift for the 21 surgical treatment of prolapse are irrelevant. (#196, at 6–7). Ethicon argues these opinions are 22 irrelevant because they are about traditional procedures and not medical devices and thus these 23 opinions cannot “inform the issue of whether an alternative design for a product exists.” Id. at 7. 24 Plaintiffs argue that regarding POP, the design of the mesh used in Prolift makes it less effective 25 than the traditional procedures that do not use mesh, and that Ethicon knew that synthetic, non- 26 absorbable mesh was more likely to cause complications. (#206, at 3). Regarding the TVT mesh, 27 Plaintiffs argue that although Dr. Elliott notes in his deposition that the Burch procedure and 28 autologous slings are not medical devices and it’s like comparing “apples to oranges,” the main 1 difference is between long-term data and short-term data. Id. 2 The Court is convinced by Defendant’s argument that Dr. Elliott’s referral to alternative 3 procedures do not entail changing the design of Prolift or TVT, but rather he advocates 4 eliminating them from SUI surgeries altogether “and utilizing a completely different surgical 5 alternative.” (#219, at 6). The Court finds that alternative procedures or surgeries do not inform 6 the jury how Ethicon could have made Prolift or TVT devices themselves safer to avoid the 7 complications being claimed here. Further, this opinion could cause the jury to confuse the issues 8 or waste time. See Fed. R. Evid. 403. 9 Plaintiffs also argue that Dr. Elliott’s opinions are relevant to Ethicon’s failure to warn and 10 will help the jury to decide whether Ethicon included sufficient warnings with the TVT and 11 Prolift mesh kits because of all the data comparing traditional surgical procedures and medical 12 devices using mesh. Id. at 5. “Under Nevada law, to prove a failure to warn claim, a plaintiff 13 must show (1) the product had a defect which rendered it unreasonably dangerous, (2) the defect 14 existed at the time the product left the manufacturer, and (3) the defect caused the plaintiff’s 15 injury.” Heinrich v. Ethicon, Inc., 455 F.Supp.3d 968, 972–73. “A product may be found 16 unreasonably dangerous and defective if the manufacturer failed to provide an adequate 17 warning.” Id. A plaintiff must prove causation and can do so by “demonstrating that a different 18 warning would have altered the way the plaintiff used the product or would have prompted 19 plaintiff to take precautions to avoid the injury.” Id. However, “[t]he medical device 20 manufacturer… is not in the best position to weigh the risks and benefits or using the device in a 21 particular patient.” Id. at 974. “Rather, ‘the physician is in the best position to understand the 22 patient’s needs and assess the risks and benefits of a particular course of treatment.’” Id. 23 There is also no way for Ethicon “to assess the suitability of its product for a particular 24 patient in a particular situation” and there is no way for the manufacturer to “ensure that the 25 patient receives the written warnings.” Id. Especially because the traditional procedures Dr. 26 Elliott prefers are not medical devices being implanted in bodies, failing to warn patients about 27 an entirely separate medical procedure is irrelevant to whether Ethicon failed to warn patients 28 about possible defects in Prolift or TVT. Therefore, Dr. Elliott may not testify specifically that 1 the traditional procedures would have been a safer alternative than Prolift or TVT under an 2 alternative design theory. 3 2. Reliability 4 Ethicon argues that Dr. Elliott’s opinion that a device with a lighter-weight and larger-pore 5 mesh would have been safer than the mesh Prolift used is unreliable expert opinion. (#196, at 9). 6 Ethicon argues that reference to a lighter mesh–Ultrapro, which was used in Prolift+M, should 7 not be testified as a safer alternative because he does not indicate it as safer in his expert report 8 or his deposition. Id. at 9–10. Dr. Elliott stated in his deposition that because Ultrapro was 9 eventually put into Prolift+M it reinforced his opinion that “[m]esh should not be placed in the 10 vagina.” (#196-8, at 13). The Court finds that Dr. Elliott may not explicitly testify that Ultrapro 11 mesh is a safer alternative, but he may testify generally about lighter-weight and larger-pore 12 mesh being less likely to cause complications in the body. The Court determines that the medical 13 literature Dr. Elliott relies on to support his decision is reliable. The Court also finds that Dr. 14 Elliott has adequate experience and expertise to opine on this topic generally. 15 Dr. Elliott refers to many studies to support his conclusion that lighter-weight and larger-pore 16 material is safer. (#196-1, at 22–23). Defendant argues that there are flaws in these studies. (#196 17 at 11–12). Defendant will have the opportunity to cross-examine Dr. Elliott about any 18 weaknesses in these studies, feasibility issues, and FDA rejections of Ultrapro. Impeaching Dr. 19 Elliott in front of a jury is the best solution for admissible but shaky evidence. See Daubert, 509 20 U.S. 579, at 596. 21 “If the witness is relying solely or primarily on experience, then the witness must explain 22 how that experience leads to the conclusion reached, why that experience is a sufficient basis for 23 the opinion, and how that experience is reliably applied to the facts.” In re: Ethicon, Inc., MDL 24 No. 2327, 2016 WL 4500766, at *4 (S.D.W.Va., Aug. 26, 2016). In this case, the witness is 25 relying on scientific literature in addition to his experience, but regardless, the Court finds his 26 experience is sufficient to justify an opinion on lighter-weight, larger-pore mesh as better. Part of 27 Dr. Elliott’s opinion is that the Prolene mesh used in Ethicon’s devices is identical to the Prolene 28 used in hernia mesh, and it performs poorly in the abdomen, it surely performs worse in the 1 vagina. (#206, at 7). Dr. Elliott is a specialist in urogynecology and has vast experience with SUI 2 and POP, as well as the anatomical structure of the vagina. (#196-1, at 5). The Court finds his 3 experience does bridge the gap to allow Dr. Elliott to opine about different types of mesh and 4 how they interact with the vagina. 5 Finally, the Court is tasked only with screening the jury from nonsense opinions, and not 6 with judging the validity of an expert’s conclusions. See Great W. Air, LLC, 2019 WL 6529046, 7 at *3. Therefore, Dr. Elliott’s opinion testimony regarding the weight and pore size of mesh in 8 surgery is admissible. 9 iii. Dr. Elliott’s Opinions About Ethicon’s Research and Testing, Physician 10 Training, and Adverse Event Reports 11 Ethicon asks the Court to preclude Dr. Elliott from offering various opinions criticizing 12 Ethicon for failing to meet their legal duties regarding research and testing, physician training, 13 and adverse event reports because they are outside the scope of his expertise. (#196 at 18). Mrs. 14 and Mr. Carter argue in response that his opinions do not cross the line into inadmissible expert 15 opinion and that his opinions are “really just observations from a physician’s perspective of 16 undisputed facts[.]” (#206, at 10). However, the Court is unconvinced. Plaintiffs have not 17 pointed to evidence that Dr. Elliott is qualified to opine on these topics. There is nothing in his 18 background that would provide him with specialized knowledge about what testing Ethicon 19 should have performed, as is stated in his expert report. (#196-2, at 14). Even with all the clinical 20 experience Dr. Elliott has, he has never manufactured or worked on the design of a medical 21 device. 22 Mrs. and Mr. Carter have not claimed that the implanting physician, Dr. Hsieh, improperly 23 implanted the device in Mrs. Carter, thus Dr. Elliott is precluded from opining that Ethicon failed 24 to properly train their physicians on implantation of their devices. See Heinrich v. Ethicon, o. 25 2:20-cv-00166-APG-VCF, 2021 WL 2285435, at *5 (D. Nev., June 4, 2021). There is also no 26 evidence that Dr. Elliott is qualified to testify about Ethicon’s physician training as he has never 27 participated in any Prolift training. (#196-32, at 4). 28 Finally, Dr. Elliott has no relevant experience with the FDA or medical device industry that 1 | would justify him offering expert testimony regarding the standard of care for collecting and 2 | reporting adverse events at Ethicon. 3 Il. Conclusion 4 Accordingly, IT IS HEREBY ORDERED that Defendant’s Motion to Limit Opinions of 5 | Daniel Elliott, M.D. (#196) is GRANTED in part and DENIED in part.
