Spinal Cord Stimulator Litigation Expands: Is Your Firm’s Mass Tort Inventory Ready?

Spinal cord stimulators (SCS) are implanted medical devices designed to help manage chronic pain. However, ongoing mass tort litigation alleges that certain devices have caused severe complications, including electrical shock sensations, lead migration, new or worsening chronic pain, and severe injuries requiring surgical revision or explantation.

Because causation must be evaluated based on specific device records and medical histories, the litigation landscape is moving rapidly across multiple venue tracks. On October 2, 2026, the Judicial Panel on Multidistrict Litigation (JPML) issued transfer orders establishing two new manufacturer-specific Multidistrict Litigations (MDLs).

For law firms managing growing dockets, early device identification, rigorous claimant record collection, and operational readiness are now critical to navigating these proceedings.

Current Litigation Landscape: Three Distinct MDL Tracks

Initial efforts to consolidate all spinal cord stimulator claims into a single industrywide MDL were rejected by the JPML in June 2026 due to differences in regulatory histories, product designs, and corporate conduct across manufacturers. Litigation has now fractured into distinct, manufacturer-specific MDL proceedings:

Core Allegations Across the Proceedings

While each MDL focuses on specific product designs, common factual allegations underpin these cases:

• Regulatory & Premarket Approvals: Plaintiffs allege manufacturers relied on published literature regarding competitor devices to secure initial FDA premarket approvals, subsequently introducing major design modifications via successive approval supplements.

• Failure to Warn & Noncompliance: Claims cite regulatory noncompliance, insufficient post-market surveillance, and failure to disclose known failure rates to physicians and patients.

• Preemption Defense Focus: Centralization in each venue aims to streamline discovery and address dispositive preemption motions regarding FDA regulations.

Courts have already reached differing conclusions on early dismissal motions—such as a Minnesota federal court dismissing claims against Medtronic and the FDA, while a Maryland federal court allowed core claims against Nevro to proceed. Dismissal briefing on threshold legal issues remains a primary focus across all dockets.

FDA Recall Update: Boston Scientific Infinion CX Leads

Complicating the litigation environment are active safety alerts and device recalls. In September 2026, the FDA issued a recall notice regarding unused Boston Scientific Infinion CX Leads.

• The Defect: Mechanical stress near the anchor site can cause high impedance or lead fractures, leading to loss of therapeutic stimulation or requiring surgical intervention to remove or replace the lead.

• Reported Adverse Events: As of May 27, 2026, Boston Scientific had reported 1,081 serious injuries associated with the issue.

• FDA Guidance: The recall instructs healthcare facilities to remove unused affected leads from inventory. The FDA notes that this recall does not direct patients with existing implants to undergo prophylactic removal, though affected patients requiring revision must be closely tracked.

Critical Documentation Requirements for Law Firms

With litigation divided across distinct federal districts, early claimant profiling and record verification dictate where a claim proceeds, which legal defenses apply, and whether a case meets upcoming MDL census or profile form deadlines.

To maintain inventory readiness, law firms must systematically gather and verify:

1. Device Identification & Product ID: Exact manufacturer, model number, serial number, and lead lot numbers.

2. Implant & Revision Records: Operative reports detailing the initial implantation, anchor sites, programming history, and any subsequent revision surgeries.

3. Explant Records & Device Preservation: Surgical notes confirming explantation and chain-of-custody documentation for explanted hardware.

4. Symptom & Treatment Timelines: Detailed logs correlating device programming adjustments with the onset of shocks, lead migration, or new pain symptoms.
