This document relates to: 

Johns v. CR Bard et al., 

Case No. 2:18-cv-1509

 Case No. 2:18-md-2846

 JUDGE EDMUND A. SARGUS, JR.

 Magistrate Judge Kimberly A. Jolson

EVIDENTIARY MOTIONS OPINION AND ORDER NO. 9

This Opinion addresses the parties’ motions to exclude or limit the testimony of regulatory 

experts. This includes Defendants’ Motion to Exclude the Opinions and Testimony of Plaintiff’s 

Expert John L. Quick (ECF No. 32), Plaintiff’s Motion to Exclude the Opinions and Testimony of 

Defense Expert Donna-Bea Tillman, Ph.D. (ECF No. 113), Plaintiff’s Motion to Exclude the 

Opinions and Testimony of Defendants Bard’s Expert Witness Kimberly A. Trautman, M.S. (ECF 

No. 72), Plaintiff’s Motion to Exclude the Opinions and Testimony of Defense Expert Marion J. 

Fedoruk, M.D. (ECF No. 43), Plaintiff’s Motion to Exclude the Opinions and Testimony of 

Defense Expert Greg Richey (ECF No. 97), and Plaintiff’s Motion to Exclude the Opinions and 

Testimony of Defense Expert Thomas Michael Galassi, MPH, CIH (ECF No. 138). 

I. Background1

This case is the first bellwether trial, selected from thousands of cases in this 

multidistrict litigation, alleging “that defects in defendants’ polypropylene hernia mesh 

1 The Court assumes that the parties and other interested readers are familiar with the history of 

this case. For a more complete factual background, the reader is directed to the Court’s summary 

judgment opinion and order. In re Davol, Inc., Polypropylene Hernia Mesh Prods. Liab. Litig., Nos. 

2:18-md-2486, 2:18-cv-01509, 2020 WL 5223363, at *1–6 (S. D. Ohio Sept. 1, 2020).

products can lead to complications when implanted in patients, including adhesions.” In 

re Davol, Inc., Polypropylene Hernia Mesh Prods. Liab. Litig., Nos. 2:18-md-2486, 2:18-

cv-01509, 2020 WL 5223363, at *1 (S. D. Ohio Sept. 1, 2020). This includes the 

Ventralight ST, the device implanted in Plaintiff. The Ventralight ST is a prescription 

medical device used for hernia repairs. The Food and Drug Administration (“FDA”) 

cleared it for use through the premarket notification 510(k) process in 2010 and later 

cleared it for use with the Echo Positioning System in 2011. It is a multicomponent 

device made of a mesh, which consists of polypropylene, polyglycolic acid fibers, and a 

bioresorbable coating called “Sepra Technology” (“ST”). The ST-coated side of the mesh 

is placed against organs, such as the bowels, while the uncoated polypropylene side is 

placed against the fascia because the uncoated side maximizes tissue attachment and thus 

supports the hernia repair. Id. at *1–2.

Plaintiff brings this action to recover for injuries sustained as a result of the 

implantation of Defendants’ allegedly defective Ventralight ST device. Plaintiff claims 

that Defendants knew that polypropylene is unsuitable for permanent implantation in the 

human body. Id. at *4. The crux of Plaintiff’s claims is that the ST coating on Ventralight 

ST devices resorbs too quickly. Id. at *1. This leads to the exposure of bare 

polypropylene to internal organs and tissues, increasing the risk of potential 

complications. Id. at *1–3. Plaintiff alleges that this occurrence led to omental adhesions 

after his laparoscopic hernia repair surgery in 2015. Id. at *4. The following claims 

remain for trial: design defect, under negligence and strict liability theories; failure to 

warn, under negligence and strict liability theories; breach of express warranty; breach 

of implied warranty; breach of implied warranty of merchantability; negligent 

Case: 2:18-md-02846-EAS-KAJ Doc #: 528 Filed: 06/28/21 Page: 2 of 19 PAGEID #: 6906
3

misrepresentation; and punitive damages. Id. at *6–25. Now, various evidentiary 

motions are ripe for adjudication.

II. Legal Standard

“Neither the Federal Rules of Evidence nor the Federal Rules of Civil Procedure explicitly 

authorize a court to rule on an evidentiary motion in limine.” In re E.I. du Pont de Nemours & Co. 

C-8 Pers. Injury Litig., 348 F. Supp. 3d 698, 721 (S.D. Ohio 2016). The practice of ruling on such 

motions “has developed pursuant to the district court’s inherent authority to manage the course of 

trials.” Luce v. United States, 469 U.S. 38, 41 n.4 (1984). “The purpose of a motion in limine is 

to allow a court to rule on issues pertaining to evidence prior to trial to avoid delay and ensure an 

evenhanded and expedient trial.” In re E.I. du Pont, 348 F. Supp. 3d at 721 (citing Ind. Ins. Co. v. 

Gen. Elec. Co., 326 F. Supp. 2d 844, 846 (N.D. Ohio 2004)). However, courts are generally 

reluctant to grant broad exclusions of evidence before trial because “a court is almost always better 

situated during the actual trial to assess the value and utility of evidence.” Koch v. Koch Indus., 

Inc., 2 F. Supp. 2d 1385, 1388 (D. Kan. 1998); accord Sperberg v. Goodyear Tire & Rubber Co., 

519 F.2d 708, 712 (6th Cir. 1975) (“A better practice is to deal with questions of admissibility of 

evidence as they arise.”). Unless a party proves that the evidence is clearly inadmissible on all 

potential grounds—a demanding requirement—“evidentiary rulings should be deferred until trial 

so that questions of foundation, relevancy and potential prejudice may be resolved in proper 

context.” In re E.I. du Pont, 348 F. Supp. 3d at 721 (quoting Ind. Ins. Co., 326 F. Supp. 2d at 846). 

The denial, in whole or in part, of a motion in limine does not give a party license to admit all 

evidence contemplated by the motion; it simply means that the Court cannot adjudicate the motion 

outside of the trial context. Ind. Ins. Co., 326 F. Supp. 2d at 846.

The burden is on the party offering the expert testimony to demonstrate by a preponderance 

Case: 2:18-md-02846-EAS-KAJ Doc #: 528 Filed: 06/28/21 Page: 3 of 19 PAGEID #: 6907
4

of proof that the opinions of their experts are admissible. Nelson v. Tenn. Gas Pipeline Co., 243 

F.3d 244, 251 (6th Cir. 2001). Any doubts regarding the admissibility of an expert’s testimony 

should be resolved in favor of admissibility. See Jahn v. Equine Servs., PSC, 233 F.3d 382, 388 

(6th Cir. 2000) (“The Court [in Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 

(1993),] explained that Rule 702 displays a ‘liberal thrust’ with the ‘general approach of relaxing 

the traditional barriers to “opinion” testimony.’” (quoting Daubert, 509 U.S. at 588)); Fed. R. Evid. 

702 advisory committee’s note to 2000 amendment (“A review of the case law after Daubertshows 

that the rejection of expert testimony is the exception rather than the rule.”).

III. Analysis

Expert testimony is admissible if: 

(a) the expert’s scientific, technical, or other specialized knowledge will 

help the trier of fact to understand the evidence or to determine a fact in 

issue; 

(b) the testimony is based on sufficient facts or data; 

(c) the testimony is the product of reliable principles and methods; and 

(d) the expert has reliably applied the principles and methods to the facts 

of the case.

Fed. R. Evid. 702. In this circuit, “[t]he Rule 702 analysis proceeds in three stages.” 

United States v. Rios, 830 F.3d 403, 413 (6th Cir. 2016). “First, the witness must be 

qualified by ‘knowledge, skill, experience, training, or education.’ Second, the testimony 

must be relevant, meaning that it ‘will assist the trier of fact to understand the evidence 

or to determine a fact in issue.’ Third, the testimony must be reliable.” Id. (quoting In re 

Scrap Metal Antitrust Litig., 527 F.3d 517, 529 (6th Cir. 2008)).

First, an expert witness must be qualified by “knowledge, skill, experience, training, or 

education.” Fed. R. Evid. 702. “[T]he issue with regard to expert testimony is not the 

qualifications of a witness in the abstract, but whether those qualifications provide a foundation 

Case: 2:18-md-02846-EAS-KAJ Doc #: 528 Filed: 06/28/21 Page: 4 of 19 PAGEID #: 6908
5

for a witness to answer a specific question.” Madej v. Maiden, 951 F.3d 364, 370 (6th Cir. 2020) 

(quoting Berry v. City of Detroit, 25 F.3d 1342, 1351 (6th Cir. 1994)). “[T]he only thing a court 

should be concerned with in determining the qualifications of an expert is whether the expert’s 

knowledge of the subject matter is such that his opinion will likely assist the trier of fact in arriving 

at the truth. The weight of the expert’s testimony must be for the trier of fact.” Mannino v. Int’l 

Mfg. Co., 650 F.2d 846, 851 (6th Cir. 1981). A party’s expert need only meet the “‘minimal 

qualifications’ requirement—not one who could teach a graduate seminar on the subject.” Burgett

v. Troy-Bilt LLC, 579 F. App’x 372, 377 (6th Cir. 2014) (quoting Mannino, 650 F.2d at 851); see 

also Dilts v. United Grp. Servs., LLC, 500 F. App’x 440, 446 (6th Cir. 2012) (“An expert’s lack 

of experience in a particular subject matter does not render him unqualified so long as his general 

knowledge in the field can assist the trier of fact.”). 

Second, expert testimony must also be relevant, meaning it will “help the trier of fact to 

understand the evidence or to determine a fact in issue.” Bradley v. Ameristep, Inc., 800 F.3d 205, 

208 (6th Cir. 2015) (quoting United States v. Freeman, 730 F.3d 590, 599–600 (6th Cir. 2013)); 

see also Fed. R. Evid. 702(a). “Expert testimony which does not relate to any issue in the case is 

not relevant, and, ergo, non-helpful.” Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579, 591

(1993) (quoting 3 J. Weinstein & M. Berger, Weinstein’s Evidence ¶ 702[02], p. 702–18 (1988)). 

“This requirement has been interpreted to mean that scientific testimony must ‘fit’ the facts of the 

case, that is, there must be a connection between the scientific research or test result being offered 

and the disputed factual issues in the case in which the expert will testify.” Pride v. BIC Corp., 

218 F.3d 566, 578 (6th Cir. 2000) (citing Daubert, 509 U.S. at 592). This is a case-specific inquiry. 

Madej, 951 F.3d at 370 (“Whether an opinion ‘relates to an issue in the case’ or helps a jury answer 

a ‘specific question’ depends on the claims before the court.”). 

Case: 2:18-md-02846-EAS-KAJ Doc #: 528 Filed: 06/28/21 Page: 5 of 19 PAGEID #: 6909
6

Finally, expert testimony must also be reliable. Rule 702 provides the following general 

standards to assess reliability: whether “the testimony is based on sufficient facts or data,” whether 

“the testimony is the product of reliable principles and methods,” and whether “the expert has 

applied the principles and methods reliably to the facts of the case.” Fed. R. Evid. 702(b)–(d). To 

evaluate reliability of principles and methods, courts consider “‘testing, peer review, publication, 

error rates, the existence and maintenance of standards controlling the technique’s operation, and 

general acceptance in the relevant scientific community,’” though these factors “‘are not 

dispositive in every case’ and should be applied only ‘where they are reasonable measures of the 

reliability of expert testimony.’” In re Scrap Metal, 527 F.3d at 529 (citations omitted); see Kumho 

Tire Co., Ltd. v. Carmichael, 526 U.S. 137, 150 (1999) (describing these factors as “flexible” 

(quoting Daubert, 509 U.S. at 594)). The objective of the reliability requirement is to “make 

certain that an expert, whether basing testimony upon professional studies or personal experience, 

employs in the courtroom the same level of intellectual rigor that characterizes the practice of an 

expert in the relevant field.” Kumho Tire, 526 U.S. at 152. 

The parties challenge the opinions and testimony of John L. Quick, Dr. Donna-Bea

Tillman, Ph.D., Kimberly A. Trautman, Dr. Marion J. Fedoruk, M.D., and Greg Richey—all of 

whom offer a regulatory opinion or one related to Material Safety Data Sheets (“MSDSs”). 

A. John Quick

Plaintiff offers an expert report and testimony from Quick considering the adequacy of

Defendants’ Quality Management System (“QMS”) “during the relevant phases of numerous

medical device design and development processes.” (ECF No. 63 at PageID #3007.) Defendants

contend that Quick is unqualified to offer this testimony, that his opinions are irrelevant because

they lack a connection to the Ventralight ST, and his methods are unreliable. (ECF No. 32 at

Case: 2:18-md-02846-EAS-KAJ Doc #: 528 Filed: 06/28/21 Page: 6 of 19 PAGEID #: 6910
7

PageID #1108–09.) Although Quick is qualified to opine on the adequacy of Defendants’ QMS

and his opinions regarding the adequacy of Defendants’ QMS in relation to the validation of the

Sepra Technology (“ST”) are relevant, Quick’s opinions are unreliable and thus inadmissible.

As a preliminary matter, most of Quick’s opinions in his report are inadmissible due to

earlier opinions addressing motions in limine. Quick’s opinions address the QMS in place for the

Composix Kugel XL device and other devices, as well as the status of Defendants’ QMS prior to

the development of the Ventralight ST, its components, or a predicate device. (ECF No. 32-2 at

PageID #1171, 1182.) As this Court has held before, this is inadmissible character evidence

because it is being used to show that earlier inadequacies in the QMS show inadequacies in the

QMS in place at the time the Ventralight ST was designed and manufactured. In re Davol,

Inc./C.R. Bard, Inc., Polypropylene Hernia Mesh Prods. Liab. Litig., Nos. 2:18-md-2846, 2:18-

cv-1509, 2021 WL 81821, at *6 (S.D. Ohio Jan. 11, 2021); Fed. R. Evid. 404(a); see also In re

Davol, Inc./C.R. Bard, Inc., Polypropylene Hernia Mesh Prods. Liab. Litig., Nos. 2:18-md-2846,

2:18-cv-01509, 2020 WL 6440261, at *6–7 (S.D. Ohio Nov. 2, 2020) (reaching the same

conclusion for evidence of other regulatory noncompliance ices). For these reasons, Quick’s

opinions about the adequacy of the QMS in place for other devices and prior to the development

of the Ventralight ST cannot be offered to prove that the QMS in place for the Ventralight ST was

defective.2

The only portion of Quick’s report that addresses the Ventralight ST is his final section, in

which he opines that “the user need of the 14-day resorption time for the Sepra Technology was

2 Quick also opined that Genzyme, the company from which the Defendants purchased the license 

for the ST, needed to file a new 510(k) application and that the failure to do so was evidence that 

Defendants had made little progress on these QMS issues since 2006. (ECF No. 32-2 at PageID #1206–

07.) This is also inadmissible character evidence introduced to demonstrate propensity. For this reason, 

the Court need not decide whether Quick is also qualified to offer this opinion. (See ECF No. 89 at 

PageID #6072 (raising the issue).)

Case: 2:18-md-02846-EAS-KAJ Doc #: 528 Filed: 06/28/21 Page: 7 of 19 PAGEID #: 6911
8

never validated by either Genzyme or Bard in the Sepramesh products or the Ventralight ST

products.” (ECF No. 32-2 at PageID #1202.) Consequently, the only remaining opinions that

Defendants challenge in their motion are that “Bard failed to validate the Hydrogel Technology

used in the Ventralight ST hernia device” and other testimony implicated in that section of the

report on the following subjects: “[hernia] mesh,” “[a]nimal studies with regard to mesh

products,” “[b]iocompatibility testing,” and “[e]valuating or determining which tests should be

conducted during the design and development process of a hernia mesh product.” (ECF No. 32 at

PageID #1106–07.)3 Thus, Defendants’ arguments are addressed in relation to these opinions.

First, qualifications. Quick is qualified through his experience to offer opinions on the

adequacy of Defendants’ QMS in place during the design and manufacture of the Ventralight ST

and/or its components. Quick was responsible for “large medical device and drug related product

functions,” at Baxter International, Inc., focusing on sterile fluids technology and medical devices

and having all medical device operations certified based on standards from the International

Organization for Standardization (“ISO”). (Id. at PageID #1162.) He eventually served as the

“Corporate Vice President for Worldwide Quality/Regulatory.” (Id. at PageID #1162–63.) Since

2003, Quick has worked as a private consultant on quality management and regulatory compliance

“with a special emphasis in medical device quality system matters.” (Id. at PageID #1163.) He

advises medical device companies on how they can improve their quality systems and reporting to

the FDA, how to respond to FDA warning letters, and how to prepare for FDA QMS inspections.

(Id.) Additionally, Quick assists private equity firms with due diligence on pharmaceutical and

medical device companies, evaluating their quality assurance, quality control, regulatory

compliance and affairs, and manufacturing and research and development. (Id.) This is sufficient

3 Defendants list other areas of testimony as inadmissible, but because Plaintiff admits that Quick 

does not opine on those areas (ECF No. 63 at PageID #3021–23) there is no occasion to address them.

Case: 2:18-md-02846-EAS-KAJ Doc #: 528 Filed: 06/28/21 Page: 8 of 19 PAGEID #: 6912
9

to show that Mr. Quick is qualified to opine from a QMS perspective whether Defendants properly

validated the Sepra Technology, as well as each of the opinions that Defendants challenge.

Defendants argue that Quick is unqualified to offer any of these opinions because he is not

a medical doctor or chemist (ECF No. 32 at PageID #1113–14), but this is unpersuasive. 

“[I]nsistence on a certain kind of degree or background is ‘at odds with the “liberal thrust” of the

Federal Rules and their “general approach of relaxing the traditional barriers to ‘opinion’

testimony.”’ ‘The language of Rule 702 and the accompanying advisory committee notes make

clear that various kinds of “knowledge, skill, experience, training, or education,” qualify an expert

as such.’” In re Heparin Prods. Liab. Litig., 803 F. Supp. 2d 712, 731 (N.D. Ohio 2011) (citations

omitted). Here, Quick is qualified by way of his experience. 

Additionally, Defendants assert that Quick is not a hernia mesh expert (ECF No. 32 at

PageID #1113–14), but the Court can discern no reason why QMS expertise must be device

specific. FDA regulations define a “quality system” as “the organizational structure,

responsibilities, procedures, processes, and resources for implementing quality management.” 21

C.F.R. § 820.3(v). These requirements, known as the “[c]urrent good manufacturing practice,”

“govern the methods used in, and the facilities and controls used for, the design, manufacture,

packaging, labeling, storage, installation, and servicing of all finished devices intended for human

use.” Id. at § 820.1(a)(1). These are not device-specific systems. ISO standards are also not

device-specific. See ISO 13485, Medical Devices, ISO, https://www.iso.org/iso-13485-medicaldevices.html (last visited May 5, 2021). In other words, the principles of QMS appear to be

broadly applicable across various types of medical devices. 

Next, relevance. Quick’s remaining opinions are relevant to the extent that he argues

Defendants failed to have an adequate QMS in place for validation of the ST coating component

Case: 2:18-md-02846-EAS-KAJ Doc #: 528 Filed: 06/28/21 Page: 9 of 19 PAGEID #: 6913
10

of the Ventralight ST. As this Court has explained before, ISO standards are relevant to the duty

of care that Defendants owed Plaintiff. In re Davol, Inc./C.R. Bard, Inc., Polypropylene Hernia

Mesh Prods. Liab. Litig., Nos. 2:18-cv-01509, 2:18-md-2846, 2020 WL 6603657, at *7 (S.D. Ohio

Oct. 20, 2020) (citing Downing v. Hyland Pharmacy, 194 P.3d 944, 948 (Utah 2008)). Defendants

argue that Quick “did not attempt to connect his review of the design process for any Bard device

to any of the alleged injuries in this case” and that no connection exists in the record. (ECF No.

32 at PageID #1112; ECF No. 89 at PageID #6070–72.) But at the summary judgment stage, the

Court concluded that there was a genuine issue of fact whether an alternative design, including

“different formulations of the resorbable coating that is alleged to be defective here” would have

prevented Plaintiff’s injury. In re Davol, Inc./C.R. Bard, Inc., 2020 WL 5223363, at *12

(discussing Dr. Babensee’s opinions). For this reason, Plaintiff’s design defect claim survived

summary judgment. Id. Thus, Quick’s opinions are relevant to this case.

Finally, reliability. Quick’s method appears to be reliable. At the beginning of his report,

Quick outlines the need under ISO 13485 to establish “user needs” and to “validate” those needs

throughout the design process. (ECF No. 32-2 at PageID #1167.) Then, he relies on this principle

from ISO 13485 to explain why Defendants should have validated the pertinent user need for ST

coating—a fourteen-day resorption period—and how they did not successfully do so. (Id. at

PageID #1202–05.) Specifically, Quick points out various communications where officials at Bard

or Davol acknowledged the fourteen-day claim and ultimately concludes that “[n]one of the testing

on the Design Verification appear related to or otherwise validate that the end user need of a 14

days resorption window is met.” (Id. at PageID #1205.)4

 

4 Defendants contend that Quick is “a quintessential ‘expert-for-hire.’” (ECF No. 32 at PageID #1116.) But

this is not the problem with Quick’s testimony. When “a proposed expert’s testimony flows naturally from his own

current or prior research (or field work), then it may be appropriate for trial judge” to admit the testimony, which is

“in line with the notion that an expert who testifies based on research he has conducted independent of litigation

Case: 2:18-md-02846-EAS-KAJ Doc #: 528 Filed: 06/28/21 Page: 10 of 19 PAGEID #: 6914
11

However, Quick’s application of the method is unreliable because he did not review all the

pertinent materials that would indicate whether the Defendants had properly validated the 14-day

user need for the ST coating. FDA regulations require that design files or design history files for

a medical device include design validation, meaning that “the devices conform to defined user

needs.” 21 C.F.R. § 820.30. This appears to be identical to basic principles of ISO 13485. 

However, Quick admitted that he had not reviewed the entirety of the design files for the

Ventralight ST because the documents were “not very well organized.” (ECF No. 32-1 at PageID

#1144, p. 137.) Quick explained that he typically would review the entire design file but did not

here. Id. Thus, it is a significant reliability issue that Quick did not review the whole Ventralight

ST design file to form opinion that the 14-day resorption window user need for the ST coating w

was not validated. Quick also could not confirm that he had reviewed all animal studies. (ECF

No. 32-1 at PageID #1144, p. 138.) This is critical because he opined that Defendants failed to

validate the ST coating while considering one animal study that did not address the fourteen-day

resorption window. (ECF No. 32-2 at PageID #1205–06.) This user-need validation opinion

becomes markedly less reliable when the expert has not reviewed all the relevant materials related

to the validation of the user needs of Ventralight ST. For these reasons, opinion is unreliable.

In response, Plaintiff offers no arguments other than Defendants’ expert also did not review

“every document relating to the products at issue.” (ECF No. 63 at PageID #3020.) But this is

deficient. It is Plaintiff’s burden to demonstrate that his expert’s testimony is admissible, which

he fails to do here. Plaintiff does not explain why the documents Quick did review were sufficient

‘provides important, objective proof that the research comports with the dictates of good science.’” Johnson v

Manitowoc Boom Trucks, Inc., 484 F.3d 426, 435 (6th Cir. 2007) (quoting Daubert v. Merrell Dow Pharms., 43 F.3d

1311, 1317 (9th Cir. 1995)). Quick has decades of QMS experience, which shows that his testimony naturally flows

from his own current and prior experience. See id. at 435 n.2 (“A trial judge’s assessment of the prepared-solely-forlitigation factor is not, of course, a totally binary exercise. We recognize that many experts may look neither quite

like the ‘quintessential expert for hire’ in this case nor quite like a pure research scientist/engineer whose loyalties are

to the laboratory/field and not the courtroom.”). 

Case: 2:18-md-02846-EAS-KAJ Doc #: 528 Filed: 06/28/21 Page: 11 of 19 PAGEID #: 6915
12

to establish that his opinion is reliable or why the other animal studies and the design files were

unnecessary for Quick to review.

For these reasons, Quick’s testimony is inadmissible, and Defendants’ motion is granted.

B. Donna-Bea Tillman, Ph.D., MPA, FRAPS

Defendants offer Dr. Tillman as an expert witness to testify regarding “the FDA’s medical

device regulatory standards, the FDA’s 510(k) clearance process, and postmarket safety.” (ECF

No. 134 at PageID #8654.) Plaintiff moves to exclude three opinions: (1) the meaning of the

Marlex MSDS related to polypropylene used in the Ventralight ST devices, (2) opinions regarding

the FDA’s quality system regulations, and (3) any testimony relating to FDA websites that discuss

hernia mesh. Dr. Tillman’s MSDS and FDA website opinions are inadmissible, but her opinion

regarding the FDA’s quality system regulations is admissible. Thus, Plaintiff’s motion is granted

in part and denied in part.

1. MSDS meaning

Plaintiff contends that Dr. Tillman is unqualified to offer opinions about the meaning of

MSDSs in the 510(k) process because she has no experience with the Occupational Safety and

Health Administration (“OSHA”), the federal agency that requires the creation of MSDSs, and

that her methods for reaching her MSDS opinions are unreliable. (ECF No. 113 at PageID #7690–

91.) However, the Court need not address Dr. Tillman’s qualifications or the reliability of her

opinion because the Court ruled earlier that the Marlex MSDS was only admissible as evidence of 

Defendants’ knowledge and inadmissible hearsay if offered to demonstrate that polypropylene was 

unsafe for permanent implantation in the human body. In re Davol, Inc./C.R. Bard, Inc., 2020 WL 

6603657, at *4–5. Dr. Tillman’s testimony as to the meaning of MSDSs, specifically that they are

not indicative of safety for consumers or end users of polypropylene devices, is irrelevant to what 

Case: 2:18-md-02846-EAS-KAJ Doc #: 528 Filed: 06/28/21 Page: 12 of 19 PAGEID #: 6916
13

Defendants actually thought the MSDS meant or what they otherwise knew about the risks of the 

polypropylene at the time the Ventralight ST was designed and marketed. This opinion is therefore 

inadmissible.

2. FDA’s quality system regulations

Next, Plaintiff asserts that Dr. Tillman’s background discussion about the FDA’s quality 

system regulations, particularly how it fits within the regulatory scheme, is unreliable because she 

does not intend to offer an opinion about Defendants’ quality systems. (ECF No. 113 at PageID 

#7692.) Defendants agree that Dr. Tillman does not purport to offer an opinion and posit that this 

portion of her expert report is background helpful to the trier of fact. (ECF No. 134 at PageID 

#8659–60.) To the extent that Dr. Tillman provides this testimony as background and not a 

description of law, she may testify by way of her experience.

3. FDA’s hernia mesh website

Plaintiff moves to exclude Dr. Tillman’s opinions related to the FDA’s hernia mesh

specific website. (ECF No. 113 at PageID #7692.) Specifically, Plaintiff challenges Dr. Tillman’s

following opinion as unreliable because she lacks knowledge about the FDA’s process with regard

to the hernia mesh website:

In my experience, if FDA had any questions or concerns about the safety or

effectiveness of hernia mesh products current on the market, these concerns

would have been expressed on this publicly available website page.

ECF No. 113-1 at PageID #7738.) Plaintiff contends that this opinion lacks “any foundation.” 

(ECF No. 113 at PageID #7692.) The Court agrees. Even if Dr. Tillman had experience and

knowledge related to the FDA’s vetting process for websites, she lacks any knowledge about the

FDA’s vetting for this particular website because she did not participate in the vetting process. 

Case: 2:18-md-02846-EAS-KAJ Doc #: 528 Filed: 06/28/21 Page: 13 of 19 PAGEID #: 6917
14

Accordingly, her opinion is simply speculation. Dr. Tillman’s opinion regarding the FDA website

is inadmissible.

C. Kimberly A. Trautman, M.S.

Plaintiff moves to exclude the opinions and testimony of Kimberly A. Trautman, M.S. 

(ECF No. 72.) Most of Trautman’s report is general, concluding that Defendants were compliant

with FDA QMS regulations based on her review of records from 2004 to 2017, though she makes

some specific references to certain FDA communications related to the Composix Kugel device. 

(ECF No. 72-1 at PageID #4539–42.) Before addressing any of the parties’ arguments, the impact

of prior motions in limine decisions on Trautman’s opinions and testimony must be noted. 

Evidence of FDA inspections and third-party audit evidence about other devices demonstrating

non-compliance with FDA regulations is inadmissible character evidence under Federal Rule of

Evidence 404 if offered to prove the Ventralight ST’s nonconformity with FDA regulations. In re

Davol, Inc./C.R. Bard, Inc., 2021 WL 81821, at *6–7. Likewise, evidence related to FDA

compliance, as opposed to noncompliance, with other devices if offered to show compliance with

the Ventralight ST is also impermissible propensity evidence. As this Court has explained,

“character or propensity evidence may be of bad or good character; Rule 404 makes no distinction. 

Therefore, Plaintiff would have no occasion to rebut evidence of Defendants’ general good

character because it would also be inadmissible propensity evidence.” Id. at *5 (discussing

evidence that Defendants have always manufactured devices in accordance with FDA guidelines

and regulations). Thus, Defendants cannot offer Trautman’s opinion or testimony regarding their

compliance with FDA guidelines and regulations for devices other than the Ventralight ST. For

the remainder of this analysis, the only opinions considered are those that can be construed as

addressing Defendants’ compliance in designing and manufacturing the Ventralight ST.

Case: 2:18-md-02846-EAS-KAJ Doc #: 528 Filed: 06/28/21 Page: 14 of 19 PAGEID #: 6918
15

Plaintiff argues that Trautman’s opinions and testimony should be excluded because she is

unqualified to offer opinions about what the FDA believed or considered and because those

opinions are unreliable. (ECF No. 72 at PageID #4518–21.) Plaintiff does not appear to contest

that Trautman is qualified to offer opinions regarding whether Defendants were in fact in

compliance with the FDA; instead, Plaintiff takes issue with Trautman’s interpretation of certain

actions or inactions of the FDA as indicating that the FDA believed they were in compliance. (Id.

at PageID #4517–18.) Trautman is qualified to opine whether Defendants complied with FDA

regulations, but she is not qualified to opine on the opinions and beliefs of the FDA. For this

reason, there is no need to address whether her method for reaching her FDA-belief opinions are

reliable.

Trautman is eminently qualified to opine on whether Defendants were in compliance with

the FDA. She has over 30 years of experience in medical device quality systems and international

regulatory compliance/affairs, including 20 years with the FDA. (ECF No. 72-1 at PageID #4555–

58.) Trautman worked for the FDA in the Center for Devices and Radiological Health, the division

responsible for ensuring the safety of medical devices used in the United States, from 1991 to

2016. (Id.) During her tenure, Trautman wrote the current QMS regulation. Currently, Ms.

Trautman is the Executive Vice President Medical Device International Services for NSF Health

Science, a division of NSF International. (Id. at PageID #5557.) Accordingly, Trautman may

offer opinions such as that Defendants appeared to be in compliance with the QMS regulations

during the design and manufacture of the Ventralight ST.5

However, Defendants fail to show that this translates the ability to opine on the beliefs of

5 Evidence of compliance with FDA regulations is not the standard of care that the jury will 

consider. Although such compliance is evidence that the standard of care is met under Utah law. In re 

Davol, Inc./C.R. Bard, Inc., 2020 WL 6603657, at *10 (citing Downing, 194 P.3d at 948). 

Case: 2:18-md-02846-EAS-KAJ Doc #: 528 Filed: 06/28/21 Page: 15 of 19 PAGEID #: 6919
16

the FDA. For example, Trautman opines in one instance that Certificates of Foreign Governments

(“CFGs”) is “evidence that the FDA considered Davol to be in substantial compliance of the

[QMS] regulation through the vast majority of the 14 years described above.” (ECF No. 72-1 at

PageID #4546.) Although Trautman may rely on her expertise to explain the meaning of receiving

a CFG, such as that a CFG is not issued when a manufacturer is not in substantial compliance, she

cannot opine as to what the FDA believed when it issued the CFG. Expert testimony “on the

intent, motives or states of mind of corporations, regulatory agencies and others have no basis in

any relevant body of knowledge or expertise.” In re Rezulin Prods. Liab. Litig., 309 F. Supp. 2d

531, 547 (S.D.N.Y. 2004); see also In re Fosamax Prods. Liab. Litig., 645 F. Supp. 2d 164, 192

(S.D.N.Y. 2009) (granting motion to exclude an expert who was a former FDA employee “from

testifying as to as to the knowledge, motivations, intent, state of mind, or purposes of Merck, its

employees, the FDA, or FDA officials” because “her regulatory expertise does not give her the

ability to read minds.”); Rheinfrank v. Abbott Labs., Inc., No. 1:13-CV-144, 2015 WL 13022172,

at *9 (S.D. Ohio Oct. 2, 2015) (same).

An individual who was part of those decisions at the FDA might in some limited

circumstances testify to the FDA’s motivations. Trautman does not purport to be one of those

individuals. Indeed, Trautman stated that she was not involved in any investigations or evaluation

at the FDA related to Defendants. (ECF No. 111-1 at PageID #7500, p. 144.) Moreover, this

testimony would not be expert testimony, i.e. technical or scientific. See Fed. R. Evid. 702. A 

jury is free to infer that the FDA harbored such beliefs based on the FDA’s actions, with the 

assistance of Trautman’s testimony, but Trautman herself may not make this inference. In re E. I.

du Pont de Nemours & Co. C-8 Pers. Injury Litig., 345 F. Supp. 3d 897, 914 (S.D. Ohio 2015).

Defendants offer no persuasive counterarguments. Defendants argue that Plaintiff “misses 

Case: 2:18-md-02846-EAS-KAJ Doc #: 528 Filed: 06/28/21 Page: 16 of 19 PAGEID #: 6920
17

the point” by pointing out that Trautman was uninvolved in the FDA decisions behind actions such 

as the CFG given her experience with the FDA’s QMS regulations. (Id. at PageID #7468.) 

Defendants collapse the two types of opinions that Trautman gives: one as to whether Defendants

were compliant with FDA regulations and one as to whether the FDA believed that Defendants

were complaint. The first is amenable to expert evaluation, including the document review 

undertaken by Trautman. The second is a determination that only those involved in the FDA

evaluation and decision-making process can know. 

For these reasons, Plaintiff’s motion is granted as to Trautman’s non-Ventralight-ST 

compliance opinions and Trautman’s testimony and opinion regarding the FDA’s beliefs. 

D. Marion J. Fedoruk, MD

Plaintiff challenges two opinions of Dr. Fedoruk’s: “(1) the FDA’s position on whether

Material Safety Data Sheets (MSDS) are a comprehensive source of information upon which to

make a chemical risk assessment or clinical decision; and (2) the motivation of medical use

statements made in MSDS issued by certain companies.” (ECF No. 43 at PageID #2422 (footnote

omitted).) Additionally, oral argument was held on this motion. (ECF No. 298 at PageID #16566–

79.) Both of these opinions are inadmissible.

Dr. Fedoruk’s first opinion is inadmissible because it is irrelevant. The Marlex

MSDS is admissible only to prove Defendants’ knowledge of the risks presented by 

polypropylene. In re Davol, Inc./C.R. Bard, Inc, No. 2020 WL 6603657, at *4–5. Dr. 

Fedoruk’s opinion about whether the FDA views the MSDS as evidence of safety is 

irrelevant to whether the MSDS put the Defendants on notice of the risks of 

polypropylene. Supra, Part III.B.1.

Even if this previous ruling were no bar, both of Dr. Fedoruk’s opinions would 

Case: 2:18-md-02846-EAS-KAJ Doc #: 528 Filed: 06/28/21 Page: 17 of 19 PAGEID #: 6921
18

still be inadmissible. He cannot opine on the FDA’s beliefs. Supra Part III.C. Nor may 

he opine on the reason the Medical Application Caution Statement was included in the MSDS. 

This is an issue of state of mind or intent of the manufacturer of the polypropylene MSDS, which 

is inappropriate for expert testimony. Wise v. C.R. Bard, Inc., No. 2:12-cv-01378, 2015 WL 

521202, at *23 (S.D.W. Va. Feb. 7, 2015); Tyree v. Bos. Sci. Corp., 54 F. Supp. 3d 501, 574–75 

(S.D.W. Va. 2014). To the extent that Dr. Fedoruk ruled out some bases for inclusion of the 

statement in the MSDS, he may not then draw the inference why the manufacturer included the 

statement—only a jury could. In re E. I. du Pont de Nemours & Co., 345 F. Supp. 3d at 914.

Accordingly, Plaintiff’s motion is granted.

E. Greg Richey, MS, CIH, CSP, FAIHA

Plaintiff challenges Richey’s opinions “related to the content of certain MSDS documents

prepared by the manufacturers of the raw polypropylene resin used in several hernia mesh devices”

on the basis that he is unqualified to offer them and that his opinions are unreliable. (ECF No. 97

at PageID #6999.) Defendants explain that Richey provides context regarding OSHA and the Profax 6523 MSDS. (ECF NO. 125 at PageID #8522.) These opinions are irrelevant as to whether

Defendants knew of the risks of permanently implanting polypropylene—the only issue the MSDS

is admissible to prove. In re Davol, Inc./C.R. Bard, Inc., 2020 WL 6603657, at *4–5. Therefore, 

Richey’s opinions are inadmissible, supra Parts III.B.1, III.D, and Plaintiff’s motion is granted.

F. Thomas Michael Galassi, MPH, CIH

Plaintiff challenges Galassi’s opinions on “issues related to the content of certain MSDS

documents prepared by the manufacturers of the raw polypropylene resin used in several hernia

mesh devices.” (ECF No. 138 at PageID #8899). The essence of Galassi’s opinion is that the

MSDS is required by OSHA regulations, which pertain to occupational safety, i.e. safety in the

Case: 2:18-md-02846-EAS-KAJ Doc #: 528 Filed: 06/28/21 Page: 18 of 19 PAGEID #: 6922
19

workplace, not consumer or patient safety. (ECCF No. 154 at PageID #9427.) As with other

regulatory experts, Galassi’s MSDS opinions are inadmissible because they do not speak to what 

Defendants knew about the risks of polypropylene from the Marlex MSDS. Supra Parts III.B.1, 

III.D, III.E. Accordingly, Galassi’s opinions related to MSDSs are irrelevant and inadmissible. 

Plaintiff’s motion is granted.

IV. Conclusion

For these reasons, Defendants’ motion to exclude Quick’s opinions and testimony (ECF 

No. 32) is GRANTED, Plaintiff’s motion to exclude Dr. Tillman’s opinions and testimony (ECF 

No. 113) is GRANTED IN PART and DENIED IN PART, Plaintiff’s motion to exclude 

Trautman’s opinions and testimony (ECF No. 72) is GRANTED IN PART and DENIED IN 

PART, Plaintiff’s motion to exclude Dr. Fedoruk’s opinions and testimony (ECF No. 43) is 

GRANTED, Plaintiff’s motion to exclude Richey’s opinions and testimony (ECF No. 97) is 

GRANTED, and Plaintiff’s motion to exclude Galassi’s opinions and testimony (ECF No. 138) is 

GRANTED.

IT IS SO ORDERED.
