Filing a Lawsuit for Defective Medical Implants and Devices in New Hampshire

Undergoing painful revision surgery at Dartmouth Hitchcock Medical Center in Lebanon or Catholic Medical Center in Manchester because a surgical implant degraded inside your body is a devastating ordeal. When an orthopedic joint replacement leaches toxic metal ions into your bloodstream, a surgical mesh erodes through internal tissue, or an implanted cardiac defibrillator suffers premature battery depletion, the legal remedy does not involve suing your surgeon for medical malpractice. Instead, injured patients pursue strict product liability lawsuits directly against the biomedical corporations that designed, manufactured, and marketed the faulty hardware.

New Hampshire occupies a prominent position in national medical device litigation. Not only did the U.S. District Court for the District of New Hampshire, Concord serve as the federal multidistrict litigation hub for thousands of hernia mesh lawsuits against Merrimack-based Atrium Medical Corporation, but New Hampshire state law also offers extraordinarily favorable consumer protections. Because the New Hampshire Supreme Court invalidated the state's 12-year product liability statute of repose in Heath v. Sears, Roebuck & Co., 123 N.H. 512 (NH Supreme Court 1983), patients whose hip implants, knee prosthetics, or pelvic mesh fail 10 or 15 years after their original implantation surgery are not time-barred by an arbitrary device-age cutoff.

Specific Defective Medical Implants and Devices Litigated in New Hampshire

Under N.H. Rev. Stat. Ann. § 507-D:1, biomedical manufacturers are subject to product liability actions for design defects, manufacturing contamination, and inadequate warnings to treating physicians. In New Hampshire, design defect claims are evaluated under the consumer-friendly risk-utility balancing test articulated in Vautour v. Body Masters Sports Industries, Inc., 147 N.H. 150 (NH Supreme Court 2001), which asks whether the magnitude of the implant's danger outweighs its clinical utility.

Defective Hip and Knee Replacements (Metallosis)

Orthopedic joint prosthetics are engineered to withstand decades of biomechanical load, yet numerous hip and knee systems have failed within a few years of implantation. Metal-on-metal hip implants-where both the femoral head ball and the acetabular cup liner are forged from cobalt-chromium alloys-can grind together during normal walking, releasing microscopic metallic debris into surrounding hip tissue. This triggers metallosis, pseudotumors, bone necrosis, and systemic cobalt-chromium toxicity. Similarly, defective knee replacement systems have been recalled or litigated due to premature polyethylene tibial insert wear and high-viscosity bone cement debonding, forcing patients to undergo invasive surgical extraction and bone reconstruction.

Transvaginal and Hernia Mesh Complications

Surgical mesh devices made from synthetic polypropylene or coated with biological oils (such as the omega-3 fatty acid coating at issue in the New Hampshire federal litigation against Atrium Medical Corp.) frequently trigger severe chronic foreign-body reactions. Once implanted for hernia repair or pelvic organ prolapse, defective polypropylene mesh can oxidize, contract, shrink, and harden inside the abdomen or pelvis. This mechanical deformation leads to nerve entrapment, chronic debilitating pain, mesh migration, bowel perforation, fistulas, and dense internal adhesions requiring multi-stage explant surgeries.

Recalled Pacemakers and Defibrillators

Implantable cardioverter-defibrillators (ICDs), pacemakers, and spinal cord stimulators are life-sustaining Class III electronic devices. Biomedical lawsuits involving cardiac hardware typically center on fractured lead wires that deliver inappropriate high-voltage shocks to the heart, defective lithium-cluster batteries that short-circuit without warning, or moisture intrusion caused by faulty hermetic sealing during the manufacturing process.

FDA Preemption vs. State Law Claims in NH

Whether and how you can sue a medical device manufacturer in New Hampshire depends heavily on the regulatory pathway the U.S. Food and Drug Administration, Silver Spring used to allow the device onto the market under the 21 U.S.C. § 360k(a).

• 510(k) Substantial Equivalence Clearance (No Federal Preemption): The vast majority of hip implants, knee replacements, and hernia or transvaginal mesh products enter the market through the FDA's fast-track 510(k) clearance process by claiming they are substantially equivalent to an older predicate device. Under the U.S. Supreme Court's ruling in Medtronic, Inc. v. Lohr, 518 U.S. 470 (US Supreme Court 1996), 510(k) clearance is not a federal safety determination, meaning New Hampshire state law strict liability, design defect, and failure-to-warn claims are not preempted.
• Class III Premarket Approval (PMA) and Parallel Claims: High-risk life-supporting devices like pacemakers and defibrillators undergo rigorous Premarket Approval (PMA). Under Riegel v. Medtronic, Inc., 552 U.S. 312 (US Supreme Court 2008), federal law expressly preempts state tort claims that impose requirements different from or in addition to federal PMA mandates. However, injured New Hampshire patients can still pursue parallel state law claims by proving the manufacturer violated specific FDA Current Good Manufacturing Practice (CGMP) regulations under 21 C.F.R. § 820.1, such as failing to sterilize components properly or deviating from approved PMA specifications.

Step-by-Step Process for Filing a Medical Device Lawsuit in New Hampshire

If you live in Manchester, Nashua, Concord, Dover, or anywhere in New Hampshire and face complications or revision surgery from a faulty implant, following these steps preserves critical evidence.

Step 1: Preserve the Explanted Hardware Before Revision Surgery

Hospitals routinely discard removed orthopedic prosthetics and pathology specimens as biohazardous medical waste unless instructed otherwise. Before undergoing revision or explant surgery, sign a written directive instructing your surgeon and the hospital pathology department to preserve the explanted device in a dry, sterile container (without destructive formalin fixatives if polymer analysis is needed) and release it directly to you or your product liability attorney.

Step 2: Obtain Operative Reports and Product Identification Stickers

Request the intraoperative nursing chart and implant log from your original implantation surgery. Every surgical implant comes with peel-off manufacturer stickers containing the exact Brand Name, Reference/Catalog Number, Lot Number, and Unique Device Identifier (UDI). You cannot sue a biomedical company without proving which exact company manufactured your hardware.

Step 3: Check FDA MAUDE Reports and File a MedWatch Report

Your attorney will cross-reference your device's lot number against the FDA's Manufacturer and User Facility Device Experience (MAUDE) database and Class I or Class II recall notices. Patients or their physicians can also document the failure by submitting Form FDA 3500B, FED, Food and Drug Administration, MedWatch Consumer Voluntary Reporting.

Step 4: File in New Hampshire Superior Court, Federal Court, or an Active MDL

Individual state lawsuits seeking over $25,000 are filed using Form NHJB-2688-Se, New Hampshire, Judicial Branch, Civil Complaint in county venues such as the Hillsborough County Superior Court, Northern District, Manchester, the Grafton County Superior Court, North Haverhill, or the Merrimack County Superior Court, Concord. Frequently, defective implant cases are filed directly in the U.S. District Court for the District of New Hampshire, Concord using Form JS 44, FED, U.S. Courts, Civil Cover Sheet or transferred into a consolidated federal Multidistrict Litigation (MDL) under 28 U.S.C. § 1407 for coordinated pretrial discovery.

How Much Does it Cost in New Hampshire?

Biomedical device lawsuits require metallurgists, biomaterials pathologists, and regulatory experts whose fees can reach tens of thousands of dollars. By hiring a New Hampshire product liability lawyer from our directory, all litigation expenses are advanced on a contingency basis.

• New Hampshire Superior Court Filing Fee: $325.00 for original entry of a civil complaint (waivable for qualifying low-income residents via Form NHJB-2849-S, New Hampshire, Judicial Branch, Application for Waiver of Superior Court Fees and Costs).
• U.S. District Court Filing Fee (Concord / MDL): $405.00 civil filing fee under 28 U.S.C. § 1914(a).
• Pathology Preservation and Retrieval Costs: Independent laboratory storage and non-destructive scanning of explanted prosthetics or mesh specimens typically cost $500 to $2,500, paid upfront by your legal counsel.
• Contingency Attorney Fees: Standard legal fees range from 33.3% to 40% of the final settlement or judgment, with zero out-of-pocket fees owed if the case is unsuccessful.

How Long Does the Process Take?

Under New Hampshire's discovery rule codified in N.H. Rev. Stat. Ann. § 508:4(I), the 3-year statute of limitations does not begin to run on the day the device was implanted; rather, it begins when you discover-or in the exercise of reasonable diligence should have discovered-that your injury was causally linked to a defective implant (such as when a doctor diagnoses metallosis, mesh erosion, or lead fracture, or when a recall notice is issued). Once filed, individual lawsuits or federal MDL bellwether tracks typically take 2 to 4 years to resolve through global settlement matrices or trial.
