Hernia mesh litigation is one of the largest ongoing mass tort actions in the United States. Polypropylene mesh devices implanted during inguinal, ventral, and incisional hernia repairs have been associated with a pattern of serious defects — including mesh shrinkage, migration, erosion into adjacent organs, bacterial colonization, and nerve entrapment — that manufacturers knew about for years before disclosing to physicians or patients. The primary defendants include Davol Inc. and its parent C.R. Bard (now part of Becton Dickinson), Ethicon (a Johnson and Johnson subsidiary), Atrium Medical, and Covidien (now part of Medtronic). The federal multidistrict litigation MDL 2846 in the Southern District of Ohio has consolidated thousands of Davol/C.R. Bard claims for coordinated pre-trial proceedings. Separately, Ethicon mesh cases are coordinated in New Jersey Superior Court (MCL 616). Patients who underwent hernia repair surgery and subsequently experienced complications are urged to seek legal evaluation immediately — statutes of limitations are running and evidence must be preserved.
Litigation Timeline
Claim Resolution — Settlement or Trial
Mass tort hernia mesh claims resolve through one of two pathways: global or individual settlement negotiated based on the injury tier grid established through bellwether trials and MDL discovery, or remand to the plaintiff's home district for individual trial. Most claimants resolve through settlement. Settlement funds are distributed after attorney fees, case expenses, and any applicable Medicare or Medicaid liens are deducted. Patients who received government-funded treatment (Medicare, Medicaid) must resolve those liens as part of the settlement process. Final net recovery is typically distributed within 6-12 months of global settlement announcement.
legalMDL Consolidation and Case Filing
Attorney files the plaintiff's complaint in federal court, which is then transferred by the Judicial Panel on Multidistrict Litigation to MDL 2846 in the Southern District of Ohio (for Davol/C.R. Bard claims) or the applicable MDL/state coordination for other defendants. The plaintiff must complete a Plaintiff Fact Sheet (PFS) and produce all medical records. Discovery in the MDL includes defendant document production, expert depositions, and plaintiff depositions. Bellwether trials are selected and tried to inform global settlement negotiations. Individual cases are not tried in the MDL — they are either resolved by settlement or remanded to home districts for trial.
legalRevision or Explantation Surgery
Surgeon performs revision surgery to address the mesh complication — which may involve adhesiolysis, partial mesh removal, complete mesh explantation, bowel resection, or hernia re-repair with biological mesh. The operative report from this surgery, along with pathology reports from tissue samples, provides the most powerful evidence in the legal claim. Patients should request all operative notes, pathology reports, and implant identification records from both the original implant surgery and the revision surgery. Revision surgery typically causes significant additional recovery time and expense, both of which are compensable damages.
medicalComplications Develop — Seek Medical Evaluation
Patient begins experiencing symptoms that may indicate mesh failure — persistent pain at the surgical site, signs of infection (redness, drainage, fever), recurrence of hernia bulge, or gastrointestinal symptoms suggesting bowel adhesion. The critical legal moment is when a physician first attributes symptoms to the mesh implant, as this often triggers the discovery rule statute of limitations clock. Patients should document all symptoms in a journal, keep all medical appointment records, and request copies of all imaging studies (CT scans, MRIs, ultrasounds) taken during this period.
medicalHernia Surgery with Mesh Implantation
Patient undergoes inguinal, ventral, or incisional hernia repair surgery. Surgeon implants synthetic polypropylene or composite mesh to reinforce the hernia defect. The operative report and implant sticker document the exact mesh product, manufacturer, lot number, and catalog number. This record is the foundation of any future legal claim and must be obtained from the hospital. Patients are typically discharged within 1-3 days for open repairs or the same day for laparoscopic procedures and advised of expected recovery timelines.
medicalNotable Verdicts & Settlements
Trevino v. C.R. Bard Inc. (S.D. Ohio — MDL 2846 Bellwether)
Jury VerdictPlaintiff received Davol Composix E/X mesh for ventral hernia repair in 2016. Developed mesh migration and dense bowel adhesions requiring two revision surgeries and partial small bowel resection. Jury found C.R. Bard liable on design defect and failure to warn theories. Award included $1.8M compensatory and $3.4M punitive damages based on evidence Bard concealed known complication rates from the FDA and prescribing surgeons.
Bellwether v. Davol Inc. (S.D. Ohio — MDL 2846)
Jury VerdictMale plaintiff received Bard 3DMax mesh for bilateral inguinal hernia repair in 2018. Developed severe inguinodynia and testicular pain within 8 months, ultimately requiring left-side mesh explantation and neurectomy. Chronic pain persisted post-explantation. Jury awarded $1.2M for past and future medical expenses, $800K pain and suffering, and $800K for loss of enjoyment of life. Defense challenged causation; plaintiff's biomaterials expert established mesh shrinkage causation.
Morrison v. Ethicon Inc. (NJ Superior Court, Bergen County)
Jury VerdictPlaintiff implanted with Ethicon Physiomesh in 2014 developed multiple mesh-related complications requiring four revision surgeries over six years, including colostomy that was later reversed. Jury found Ethicon engaged in fraudulent concealment of Physiomesh complication data from independent registry studies that showed higher-than-reported failure rates. Compensatory award of $10M plus $25M punitive damages. Case is under appeal but remains the highest reported hernia mesh verdict.
Patterson v. C.R. Bard Inc. (D. Del.)
SettlementPlaintiff received Bard Ventralex ST mesh for umbilical hernia repair. Developed surgical site infection 14 months post-implant that failed to clear with two antibiotic courses. Complete mesh explantation required; hernia recurred after explantation requiring repair with biological mesh. Total medical expenses exceeded $140K. Settlement reached during trial after plaintiff's infection expert testified regarding mesh biofilm formation.
Nguyen v. Davol Inc. (S.D. Ohio — MDL 2846)
SettlementFemale plaintiff received Composix E/X mesh for incisional hernia repair following C-section. Developed chronic pelvic pain and mesh erosion into bladder requiring cystoscopic and open surgical intervention. Single revision surgery with partial mesh removal. Settled prior to bellwether selection based on MDL discovery record and comparable bellwether outcomes. Plaintiff was 38 at time of original surgery.
Russo v. Atrium Medical Corp. (D.N.H.)
SettlementPlaintiff received Atrium C-QUR mesh for inguinal hernia repair. C-QUR's omega-3 fatty acid coating was alleged to degrade inconsistently, leaving exposed polypropylene against bowel. Plaintiff developed adhesion-related small bowel obstruction requiring emergency surgery and 12-day hospitalization. Case resolved favorably after plaintiff's biomaterials expert testified on C-QUR coating failure mechanisms documented in Atrium's internal testing data.
Watkins v. Ethicon Inc. (MCL 616, NJ Superior Court)
SettlementPlaintiff received Ethicon Proceed mesh for ventral hernia repair in 2017. Developed hernia recurrence and mesh contracture causing significant chronic pain. Single revision surgery with mesh removal and re-repair. Settlement reached through MCL 616 case management process. Plaintiff's damages were primarily chronic pain and lost wages during 14 weeks of post-revision recovery.
Sullivan v. C.R. Bard Inc. (D. Mass.)
SettlementPlaintiff received Bard Marlex mesh for inguinal hernia repair in 2019. Developed post-operative infection treated successfully with 6 weeks of oral antibiotics. No revision surgery required. Moderate groin pain resolved substantially within 18 months. Case settled for nuisance value based on absence of revision surgery and documented full clinical recovery. Illustrates the impact of injury severity on settlement value.
