Spinal Cord Stimulator Lawsuit Status

Spinal cord stimulator lawsuits are being pursued on behalf of individuals who experienced serious complications after receiving a spinal cord stimulation (SCS) device for pain management. For many recipients, the procedure was recommended after years of chronic back pain or nerve pain, making the failure of the implanted device especially devastating.

In many of these cases, the spinal cord stimulator problems center on the lead wires, the thin insulated wires placed near the spinal cord that deliver electrical signals to block pain. Lawsuits allege that some of these lead components may have been improperly manufactured, leading to premature fracture, migration out of position, loss of pain relief or painful electrical shocks. When these failures occur, patients often require additional surgery to reposition or remove the device.

As the number of lawsuits continues to grow, plaintiffs have begun seeking to coordinate the litigation in federal court. On February 20, 2026, a motion was filed with the U.S. Judicial Panel on Multidistrict Litigation requesting that spinal cord stimulator lawsuits involving Abbott Laboratories and Boston Scientific be consolidated before one judge for coordinated pretrial proceedings. The filing indicates that at least 15 related cases are already pending in federal courts nationwide, each raising similar allegations involving device malfunctions, lead failures and neurological injuries. If the JPML grants the request, the cases would proceed as a multidistrict litigation, allowing discovery and other pretrial matters to be managed in a single court as additional claims are filed.

The spinal cord stimulator injury lawyers at Saiontz & Kirk are evaluating product liability claims against major medical device manufacturers including Abbott, Boston Scientific, Medtronic, Nevro, St. Jude Medical and others. Individuals who required revision or removal surgery, experienced worsening chronic pain or suffered electrical shocks after implantation may be eligible to pursue a spinal cord stimulator lawsuit if the device malfunction was linked to a manufacturing defect.

How Does a Spinal Cord Stimulator Work?

Your nerves carry pain messages from your back or legs up through your spinal cord to your brain. A spinal cord stimulator works by sending small electrical signals through the lead wires to “mask” or disrupt those pain messages.

The goal is not to fix the injury itself. Instead, the device is meant to reduce how much pain you feel so you can move better, sleep better and rely less on pain medication.

What Conditions Are Spinal Cord Stimulators Used to Treat?

Spinal cord stimulation devices are often used to treat severe injuries such as:

• Chronic back pain
• Chronic nerve pain
• Failed back surgery syndrome
• Complex regional pain syndrome
• Long-term pain after work injuries

Most people first go through a trial period where temporary wires are placed to see if the device helps reduce their pain. If the trial provides relief, a permanent spinal cord stimulator is implanted during surgery.

However, a growing number of reports have identified SCS lead wire fractures and migrations occurring after permanent implantation, sometimes requiring additional surgery to correct the problem.

Spinal Cord Stimulator Lead Wire Failures and Device Migration

Spinal cord stimulator lawsuits often center on problems involving the device’s lead wires. These thin, insulated wires are placed in the epidural space near the spinal cord and are responsible for delivering the electrical pulses that block pain signals.

Since the entire system depends on these leads functioning properly, even minor problems in how they are manufactured can cause the device to stop working correctly. When a lead fails, the stimulator cannot deliver consistent electrical impulses, and patients may immediately notice worsening pain or abnormal sensations.

Alleged Manufacturing Defects Involving Lead Components

According to allegations raised in complaints, certain spinal cord stimulator devices may not have been manufactured in strict compliance with required federal quality control standards. These cases do not claim that spinal cord stimulation therapy itself is defective. Instead, they focus on whether specific implanted devices failed because critical components, particularly the lead wires, did not meet approved manufacturing specifications.

When those lead components are not properly manufactured, the results can be mechanical failure inside the body.

For example, if an SCS lead wire fractures, it can interrupt the electrical pathway that delivers stimulation. If a lead migrates, meaning it shifts from its original position near the spinal cord, the electrical pulses may no longer target the intended nerves. Patients may then experience sudden loss of pain relief, jolting electrical shocks, burning sensations or worsening chronic pain.

Complaints have identified several types of alleged manufacturing problems involving spinal cord stimulator lead components, including:

• Structural weaknesses that may cause premature lead wire fracture
• Improper anchoring or stabilization that allows leads to migrate out of position
• Insulation defects that permit unintended electrical discharge
• Inconsistent internal conductivity resulting in therapy interruption
• Failures to properly validate or monitor manufacturing processes

Some complaints further allege that certain devices may have deviated from approved manufacturing processes governing firmware execution, electrical stability or component validation. In these situations, the stimulator may shut off unexpectedly, deliver inconsistent stimulation or require repeated reprogramming before ultimately failing.

These mechanical failures often lead to the spinal cord stimulator side effects and neurological symptoms described in the next section.

Spinal Cord Stimulator Side Effects and Symptoms

When a spinal cord stimulator malfunctions, individuals may experience serious side effects that go beyond normal post-surgical discomfort. These complications often occur when lead wires fracture, migrate or fail to deliver consistent electrical impulses to the spinal cord.

In many spinal cord stimulator cases, individuals report worsening symptoms months after implantation, particularly when the implanted device begins to malfunction.

Common Spinal Cord Stimulator Complications and Symptoms

Patients who experienced spinal cord stimulator complications have reported:

• Worsening chronic pain
• Severe nerve pain
• Debilitating back pain
• Sudden loss of pain relief
• Electrical shocks or jolting sensations
• Overstimulation or burning sensations
• Spinal cord compression
• Spinal nerve root irritation
• Muscle weakness
• Numbness or tingling in the limbs
• Infection at the implant site
• Swelling or inflammation near the spinal canal
• Developed chest pain related to device malfunction
• Headaches or neurological symptoms
• Abnormal device behavior during charging
• Therapy shutting off unexpectedly

In more serious cases, individuals have required revision surgery to reposition fractured leads or remove the device entirely. Some underwent multiple surgeries after continued malfunction.

Since spinal cord stimulators are intended to manage chronic intractable pain, the loss of therapy combined with worsening pain can significantly impact daily function, mobility and quality of life can decline quickly.

For some patients, spinal cord stimulator injuries have resulted in permanent nerve damage or long-term spinal cord complications.

Spinal Cord Stimulator Manufacturers Named in Lawsuits

Spinal cord stimulator lawsuits are being pursued against several major medical device manufacturers. Rather than focusing on general design concerns, many of these cases center on allegations that certain spinal cord stimulation devices were not manufactured in accordance with FDA-approved specifications and quality system requirements, particularly with respect to lead wire integrity and device performance consistency.

Abbott Spinal Cord Stimulator Lawsuit

Spinal cord stimulator lawsuits are being filed against Abbott Laboratories alleging that certain Abbott spinal cord stimulator devices, including systems marketed under the Eterna and Proclaim platforms, may have deviated from approved manufacturing standards.

While some of these devices were originally sold as St. Jude spinal cord stimulators, Abbott acquired St. Jude Medical in January 2026 for approximately $25 billion, assuming liability for failures linked to St. Jude SCS devices manufactured before the sale.

According to allegations raised in recent complaints, some Abbott systems and St. Jude systems failed to consistently deliver stable therapy and may have been manufactured in a way that did not comply with federal quality standards.

Plaintiffs claim the devices experienced problems involving internal firmware controls, lead components, and battery or charging systems. These alleged defects have been linked to loss of pain relief, painful electrical shocks, unexpected therapy shutdowns, and lead migration that required additional surgeries.
