The Boston Scientific spinal cord stimulator proceedings turn on federal preemption for FDA-approved implanted devices. A spinal cord stimulator — a totally implanted system that sends electrical pulses to reduce chronic pain — usually cannot be challenged on design or warnings when the FDA set device-specific safety requirements. According to the Judicial Panel's transfer order, ten actions from four districts were centralized as MDL No.
3181 before Judge Josephine L. Staton in the Central District of California on June 5, 2026. Centralization covers pretrial work only, so surviving cases return to their home courts for trial.

Where will these cases move next?
The Judicial Panel says centralization under 28 U.S.C. §1407 needs common fact questions plus convenience and just conduct. It avoids duplicate discovery and conflicting pretrial rulings.
For injured patients, this means one judge manages records, experts, and early motions. Settlement talks, if any, also happen in one place. Trial still happens in the original court if the case survives.
Why does FDA approval matter so much?
FDA AccessData records show Boston Scientific's Precision system held premarket approval P030017 from April 2004, with later WaveWriter supplements. These totally implanted stimulators sit in Class III, which needs reasonable assurance of safety and effectiveness.
Class III is the strictest device class. FDA approval there sets federal requirements for design, manufacture, and labeling. Those federal requirements trigger the preemption fight.
Which injury claims does federal law block?
The express-preemption statute bars states from adding device requirements that differ from federal safety requirements. The text published by Cornell's Legal Information Institute in 21 U.S.C. §360k controls this boundary. Under Riegel v. Medtronic, 552 U.S.
312, courts ask two questions. First, did FDA impose device-specific requirements through premarket approval. Second, would the state tort claim add a different safety requirement. A yes to both means the claim is expressly preempted. That test often blocks design-defect and failure-to-warn claims for approved stimulators. A jury cannot demand a safer design or stronger warning than FDA approved.
What narrow path can still survive?
A Reed Smith analysis published by Medical Device Online explains that only narrow parallel claims survive. The plaintiff must allege violation of an identifiable FDA or approval requirement that matches a traditional state duty, such as building outside approved specifications. The same analysis explains the second shield from Buckman Co. v.
Plaintiffs' Legal Committee, 531 U.S. 341. Private fraud-on-FDA or pure federal-enforcement claims are impliedly preempted because 21 U.S.C. §337(a) reserves enforcement to the United States. A usable complaint therefore must tie injury to a concrete federal breach:.
- identify the approval specification or manufacturing rule at issue
- show how this device departed from that rule
- link that departure to the injury under normal state law
Does the Infinion CX recall create a claim?
FDA's recall notice of Sept. 3, 2026 says Boston Scientific removed unused Infinion CX lead kits SC-2317-50/70. The reason was anchor-site stress that could cause high impedance or fracture.
FDA counted 1,081 serious injuries and no deaths reported by May 27, 2026. A recall alone does not prove a parallel violation. A patient still needs proof that an implanted lead broke or lost function from that defect, plus medical records tying revision surgery or harm to it.
- keep the implant card, operative reports, and programming records
- ask the surgeon whether the lead will be saved after removal
- get legal review before signing a device-return or release form
