consideration because briefing is complete.
case resides in one of seven MDLs assigned to me by the
Judicial Panel on Multidistrict Litigation concerning the use
of transvaginal surgical mesh to treat pelvic organ prolapse
(“POP”) and stress urinary incontinence
(“SUI”). In the seven MDLs, there are more than
60, 000 cases currently pending, approximately 28, 000 of
which are in this MDL, which involves defendants Johnson &
Johnson and Ethicon, Inc. (collectively
“Ethicon”), among others.
MDL, the court's tasks include “resolv[ing]
pretrial issues in a timely and expeditious manner” and
“resolv[ing] important evidentiary disputes.”
Barbara J. Rothstein & Catherine R. Borden, Fed. Judicial
Ctr., Managing Multidistrict Litigation in
Products Liability Cases 3 (2011). To handle motions to
exclude or to limit expert testimony pursuant to Daubert
v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579
(1993), the court developed a specific procedure. In Pretrial
Order (“PTO”) No. 217, the court instructed the
parties to file general causation Daubert motions in
the main MDL and specific causation Daubert motions,
responses, and replies in the individual member cases. To the
extent that an expert is both a general and specific
causation expert, the parties were advised that that they
could file a general causation motion in the main MDL 2327
and a specific causation motion in an individual member case.

the parties should be intimately familiar with Rule 702 of
the Federal Rules of Evidence and Daubert, so the
court will not linger for long on these standards.
testimony is admissible if the expert is qualified and if his
or her expert testimony is reliable and relevant. Fed.R.Evid.
702; see also Daubert, 509 U.S. at 597. An expert
may be qualified to offer expert testimony based on his or
her “knowledge, skill, experience, training, or
education.” Fed.R.Evid. 702. Reliability may turn on
the consideration of several factors:
(1) whether a theory or technique can be or has been tested;
(2) whether it has been subjected to peer review and
publication; (3) whether a technique has a high known or
potential rate of error and whether there are standards
controlling its operation; and (4) whether the theory or
technique enjoys general acceptance within a relevant

(4th Cir. 2001) (citing Daubert, 509 U.S. at
592-94). But these factors are neither necessary to nor
determinative of reliability in all cases; the inquiry is
flexible and puts “principles and methodology”
above conclusions and outcomes. Daubert, 509 U.S. at
595; see also Kumho Tire Co. v. Carmichael, 525 U.S.
137, 141, 150 (1999). Finally, and simply, relevance turns on
whether the expert testimony relates to any issues in the
case. See, e.g., Daubert, 509 U.S. at
591-92 (discussing relevance and helpfulness).
context of specific causation expert opinions, the Fourth
Circuit has held that plaintiffs may use “a reliable
differential diagnosis[, which] provides a valid foundation
for an expert opinion.” Westberry v. Gislaved Gummi
AB, 178 F.3d 257, 263 (4th Cir. 1999).
A reliable differential diagnosis typically, though not
invariably, is performed after ‘physical examinations,
the taking of medical histories, and the review of clinical
tests, including laboratory tests, ' and generally is
accomplished by determining the possible causes for the
patient's symptoms and then eliminating each of these
potential causes until reaching one that ...
