Boston Scientific Spinal Cord Stimulator Lawsuits

Boston Scientific spinal cord stimulator lawsuits are moving forward and our lawyers are taking calls from victims with claims every day.

What are these cases about? In September 2026, the FDA announced a Class I recall involving certain Boston Scientific Infinion CX leads after the manufacturer reported 1,081 serious injuries. 

That is a huge number, and product injuries like this are notoriously underreported.   Patients are now bringing lawsuits alleging that the stimulators that were meant to make them feel better instead caused electrical shocks, burning sensations, lead failures, neurological injuries, and, for too many patients, more surgery.

Boston Scientific now has its own federal multidistrict litigation, MDL No. 3181, before Judge Josephine L. Staton in California. Two separate FDA actions are at play here:  the 2026 Class I recall of certain Infinion CX leads and a 2024 Class II correction involving certain WaveWriter Alpha generators. Those are different problems involving different components. We will explain both, along with the actual lawsuits, what makes a strong claim, and what we think Boston Scientific spinal cord stimulator settlement amounts might eventually look like.

August 18, 2026: Court Authorizes Direct Filing

Judge Staton authorized direct filing of qualifying Boston Scientific lawsuits in the Central District of California under Pretrial Order No. 4. A plaintiff no longer necessarily has to file elsewhere and wait for transfer to the MDL. This simplifies one part of the process.

August 13, 2026: Plaintiffs’ Leadership Appointed

The court appointed plaintiffs’ leadership to organize common discovery and other pretrial work. It is a necessary step in building this litigation. Our real interest is what happens when the lawyers get access to design history, internal complaints, regulatory submissions, and information about the conduct of device representatives. The court maintains its pretrial orders here.

June 5, 2026: Boston Scientific MDL 3181 Created

The federal judicial panel centralized Boston Scientific spinal cord stimulator cases before Judge Staton in California. The panel declined to place every spinal cord stimulator manufacturer into one giant MDL.  It is hard to say whether this is a better path for plaintiffs. Certainly, the distinction makes some sense because the manufacturers have different devices, histories, and possible failures. But we have long been able to throw multiple products with similar injuries in the same MDL.

July 17, 2024: WaveWriter Alpha Generator Correction

Boston Scientific notified physicians about a charging-related reset affecting certain WaveWriter Alpha generators. The FDA classified the action as a Class II recall. The company offered a firmware update to address the brief interruption in therapy.

Boston Scientific Spinal Cord Stimulator Recalls

Boston Scientific has had two different FDA recalls involving spinal cord stimulation devices. One involves leads that can fracture. The other involves generators that temporarily stop delivering stimulation during charging. The distinction matters because the cause of the failure is central to determining whether a patient has a viable lawsuit.

2026 Class I Infinion CX Recall: Lead Fracture and High Impedance

The FDA’s Class I recall record Z-2879-2026 identifies two affected Infinion CX lead kits:

• SC-2317-50: Infinion CX lead kit, 50 cm.
• SC-2317-70: Infinion CX lead kit, 70 cm.

Boston Scientific reported that stress at the lead’s anchoring site can cause high impedance or fractures. So the electrical connection can stop working the way it should. A patient may lose stimulation, lose the pain relief the device once provided, or face another procedure to replace the lead. The FDA’s recall database lists device design as the determined cause for this action.

There is an especially maddening feature of this kind of injury. You can spend months getting used to a permanent implant, only to be told that something has gone wrong with a lead and the answer may be another operation. Patients often have a reasonable question: how did the device get from something that worked in a trial to a permanent problem that requires more surgery? That question deserves an answer backed by records and testing.

2024 WaveWriter Alpha Recall: Charging Problems and Firmware Correction

The earlier action involved a different component. The FDA’s Class II recall record Z-2617-2024 covers certain WaveWriter Alpha implantable pulse generators, models SC-1216 and SC-1232, within specified serial number ranges.

The problem was a system check that could occur while the generator was charging. The device could reset and interrupt stimulation for approximately 10 to 15 seconds before turning it back on. Boston Scientific made an in-field firmware update available to prevent that reset behavior.

Ten seconds sounds like nothing when you are reading a software description. But if an electrical implant suddenly stops delivering therapy and then starts again, and the patient experiences a painful sensation, it is considerably more memorable. The FDA notice acknowledges that the interruption could lead patients to request surgical revision or replacement. Whether it explains any particular patient’s symptoms is something we can investigate through the model, serial number, charging history, and programming records.

Which Boston Scientific Spinal Cord Stimulators Are Involved?

Boston Scientific has sold several spinal cord stimulator systems. Patients usually remember the company name, sometimes the product family, and almost never the precise model of the lead that was implanted. I do not blame them. A person has enough to think about before surgery without memorizing a parts catalog.

Boston Scientific systems include Precision Spectra, Spectra WaveWriter, Precision Montage MRI, WaveWriter Alpha, and WaveWriter Alpha Prime. The company’s MRI device information identifies these generator models:

• Precision Spectra: SC-1132.
• Spectra WaveWriter: SC-1160.
• Precision Montage MRI: SC-1200.
• WaveWriter Alpha: SC-1216 and SC-1232.
• WaveWriter Alpha Prime: SC-1416 and SC-1432.

Older Precision and Precision Novi systems also exist. The important distinction is that a generator name does not automatically identify the lead model. Infinion 16 and Infinion CX are different.  The 2026 lead recall specifically identifies Infinion CX models SC-2317-50 and SC-2317-70.

If you need an MRI, do not make assumptions based on the product name. MRI eligibility depends on the complete implanted system and the manufacturer’s requirements. Boston Scientific provides system-specific medical procedure guidance. Your treating clinician should verify the exact device and conditions before imaging.

Boston Scientific Spinal Cord Stimulator Problems and Injuries

There is a difference between a device that did not give a patient as much pain relief as hoped and one that created a serious new medical problem. The cases that interest us most are usually the second kind, particularly when the records show a malfunction, an additional procedure, or a lasting neurological injury.

Lead Migration, Fracture, and Loss of Pain Relief

Lead migration means an electrode lead moves away from where the surgeon positioned it. Lead fracture or another electrical failure can interrupt the circuit. Both problems may leave the patient with inadequate stimulation and/or pain in unexpected places. Often, revision surgery is needed to resolve it.

We have concrete questions in these cases.  Where was the lead when it was implanted? Where is it now? What do the device interrogation records show? Was there a fracture, an anchoring problem, or some other failure?

We need comparison imaging, and we need your doctor’s thoughts (usually in the medical records). If the answer is that a lead moved, we still have to examine why. The same result can have different causes, and the cause is where the lawsuit begins.

Painful Electrical Shocks and Burning Sensations

Some plaintiffs describe being jolted by sudden electrical sensations, sometimes repeatedly, or experiencing burning pain that did not respond to another round of programming changes.

If you have never had a stimulator, it is easy to regard those symptoms as just another entry on a list of device complications. For the patient, it is a much more intimate problem. Something inside your body is delivering electrical impulses, and you cannot simply get away from it.

We want the dates the shocks began, what happened during charging, whether turning the device off helped, what the representative or doctor did next, and whether the problem continued. Those details make a much stronger case than a generic allegation that the stimulator malfunctioned.

Revision Surgery, Explantation, and Infection

One operation may lead to a second to reposition a lead, replace a component, or move the generator. Sometimes a third operation is needed to remove the entire system. Doctors call these revisions and explantations. They are clinical terms that compress an extraordinary amount of awfulness into a few syllables: another surgery, more recovery, additional pain, missed work, and often the loss of the treatment the patient had hoped would help in the first place.

We also evaluate infection claims, particularly when the infection requires device removal, additional surgery, hospitalization, or another severe response. Infection is a recognized risk of implantation. But the fact that something is a known complication does not mean a manufacturer cannot be responsible for it. We want to know what caused the infection and whether a device defect or some other preventable failure contributed to it.

Permanent Neurological Injury and Paralysis

These are the most serious cases. Permanent weakness, impaired walking, loss of sensation, paralysis, or bowel and bladder dysfunction are life-changing.  These are horrible injuries. The medical investigation must identify what happened and when. Was there cord compression, bleeding, infection, a lead problem, an electrical event, or an injury associated with the procedure? We have to link the device back to the injury.

Some victims who call us had substantial spinal problems before implantation. That does not mean you cannot bring a claim. We need to know what they could do before surgery and what they could not do afterward. The difference, documented by examinations, imaging, treatment records, and credible testimony, is often the heart of the damages case.

What the Medical Studies Tell Us

A 2026 review of 117 studies involving 20,427 participants reported permanent lead displacement in 6.64% of the patients included in that analysis. A separate 2026 review of 33 studies involving 3,445 patients reported that 24% experienced at least one adverse event and 3% at least one serious adverse event.

Those are spinal cord stimulation studies across devices and manufacturers, not Boston Scientific failure rates. But they illustrate something that should not get lost in the marketing discussions: complications and repeat procedures are significant issues in this treatment. Whether a manufacturer should be held responsible for a particular failure is the next question.

Why the Programming History Matters So Much

A patient says the device is shocking them or has stopped providing relief. So they go back to the doctor. A company representative adjusts the programming. Maybe it is better for a while. Maybe it is worse the next day. So they go back again, and the settings are adjusted again, and eventually the patient has spent months revolving through appointments without anyone producing a satisfactory explanation.

Programming is a normal part of spinal cord stimulation treatment. We agree that a company representative can provide legitimate technical assistance. But they cannot come in and act as medical providers. So we want to know who was in the room, whether the doctor was making the treatment decisions, what the representative said, what the device recorded, and what the patient reported after each visit. We do not expect a smoking gun document. What you see is a bunch of ordinary appointments, a handful of messages, a strange impedance reading, and an operative report.

What Do the Boston Scientific Lawsuits Actually Allege?

One lawsuit discussed in our spinal cord stimulator litigation coverage involves a woman whose temporary trial allegedly provided substantial pain relief. After permanent implantation of a WaveWriter Alpha system, she says she experienced shocks and burning sensations. She also alleges cardiac symptoms after activation. Reprogramming did not resolve the problem, according to her complaint.

Another plaintiff alleges that a WaveWriter Alpha device failed to provide relief, that the leads migrated, and that she needed a revision followed by removal of the system. She describes continued shocks and other symptoms despite additional programming efforts.

What they show is the kind of timeline we look for: the successful trial, the permanent implantation, the first problem, the calls and adjustments, the imaging, the additional surgery, and what the patient was left dealing with afterward. A jury understands a sequence like that. It is also much harder for a defendant to wave away than an isolated complaint of pain.

Boston Scientific MDL 3181: What Happens Next?

The federal case is In re Boston Scientific Corporation Spinal Cord Stimulator Products Liability Litigation, MDL No. 3181, in the Central District of California. Judge Josephine L. Staton oversees coordinated pretrial proceedings. The court posts its MDL orders and scheduling information.

An MDL is not a class action lawsuit. Cases are grouped so that common discovery and legal motions can be handled efficiently. But, and this is a good thing for most plaintiffs, each plaintiff has an individual injury and an individual damages claim. (Boston Scientific is in MDL 3181, Abbott is in MDL 3194, and Nevro is in MDL 3195.)

The critical questions are straightforward, even if getting the answers will be anything but straightforward. What did Boston Scientific know about lead failures and other reported problems? What did its own testing and complaint records show? How did later product modifications compare with the devices that originally went through the FDA approval process? What warnings were given to physicians, and what were the company representatives saying to patients who kept coming back with trouble?

The Federal Preemption Defense

We think we get past preemption in these cases, but it is an issue.  Boston Scientific spinal cord stimulators are Class III medical devices with FDA premarket approval histories. Under Riegel v. Medtronic, federal law can prevent state law claims that would impose requirements different from or in addition to the federal requirements governing an approved device.

Manufacturers like this defense because they can ask a judge to dismiss a case before a jury ever hears it. Plaintiffs need legally sound claims that fit within the applicable federal and state law framework, including claims based on violations of federal requirements where state law recognizes a parallel duty. The precise approval history of the component, the alleged violation, and the cause of the injury all matter.

The frustration, from a plaintiff lawyer’s perspective, is that some of the best evidence about compliance may be in the manufacturer’s hands, yet the preemption argument can arrive before full discovery. That is why the November 20 motions to dismiss matter. We will learn what Boston Scientific is actually arguing and how plaintiffs intend to answer it. We should not pretend the plaintiffs have already won that fight.

A separate procedural track also involves claims against the FDA under the Administrative Procedure Act. Those claims concern agency action. The personal injury track concerns compensation from Boston Scientific. The court is handling the two tracks separately.

Boston Scientific Spinal Cord Stimulator Settlement Amounts

As we said in the beginning, a global spinal cord stimulator settlement is likely not in the cards in the near future.  But we are bullish on these cases, and we think after a lot of work, reasonable settlement amounts will likely be offered.

We can offer preliminary projections based on injury severity and the proof required to establish it. We use the same illustrative tiers as our broader spinal cord stimulator settlement discussion. These are our estimates if the plaintiffs can establish liability and causation.

It is extremely important to keep in mind that these are settlement projections at a very early stage of the litigation.  A lot will need to go right for these predictions to come to pass.  These are “best case scenario” predictions.

These ranges overlap for a reason. A patient who needed two straightforward lead revisions may have a less valuable case than someone who underwent one operation and suffered permanent neurological damage. Counting surgeries is the easy part. Evaluating the long-term consequences and proving who caused them is where the real work is.

We also have to account for the risk that these lawsuits face. An extremely serious injury does not produce a settlement if the case is dismissed or the evidence does not connect the injury to actionable misconduct.

Who May Qualify for a Boston Scientific Spinal Cord Stimulator Lawsuit?

Our firm is reviewing selected cases with strong injury evidence. The first question is not whether a person is unhappy with the stimulator. It is what happened medically, whether there is evidence connecting the problem to the device or its manufacturer, and whether a lawsuit can still be brought.

• Implant timing: Generally, a Boston Scientific spinal cord stimulator implanted within the last ten years.
• Shocks, burns, or hardware failure: Serious symptoms involving device wiring or operation, particularly when supported by programming records, abnormal impedance, or clinical findings.
• Lead migration or fracture: Documented movement, damage, or electrical failure, especially where revision surgery was necessary.
• Explantation or revision: Removal, replacement, or repositioning of hardware because of a significant problem.
• Severe infection: Infections involving revision or removal surgery or another serious medical response.
• Neurological injury: Lasting weakness, paralysis, bowel or bladder dysfunction, or another objectively documented serious injury.

Our filing-deadline screening: We generally are not accepting cases governed by a one-year statute of limitations, but some exceptionally serious cases warrant review. Paralysis is a good example. We also generally are not accepting cases with a filing deadline in the next six months unless the injuries are extreme. These are Miller & Zois intake decisions. They do not mean that somebody outside these guidelines has no legal claim.

Explantation is particularly useful to know about. If the stimulator has been removed, or removal is scheduled, tell us when you contact the firm. The medical and technical findings associated with that surgery can be central to determining what happened.

Seven Records We Would Want to See

1. Implant identification card: Manufacturer, model, serial number, and implant date.
2. Original operative report and implant log: Exact generator and lead models, placement, and any anchors or extensions.
3. Imaging: Studies showing where the leads were originally positioned and whether they later moved.
4. Programming and device interrogation records: Settings, changes, impedance readings, alarms, charging issues, and reported symptoms.
5. Revision or explant operative reports: Why another surgery was done and what the surgeon found.
6. Company representative communications: Emails, texts, portal messages, and notes documenting what was discussed during programming visits.
7. Injury and damages records: Hospital treatment, neurological testing, infection records, rehabilitation, work loss, and continuing limitations.

Do not worry if you do not have all of these records. Most patients do not. An attorney can help obtain the appropriate records. If a device was removed, it is worth asking whether the hospital or another party still has the hardware and whether its handling has been documented. Never delay necessary medical treatment to preserve evidence.

What If You Do Not Know Your Boston Scientific Model?

That is normal. Start with your implant card or the surgeon’s operative report. Hospital implant logs generally identify both the pulse generator and the leads. You can also review Boston Scientific’s patient device information. We need the exact components eventually, but you do not have to know their names before calling us.

What Should You Do If Your Stimulator Is Causing Problems?

Serious new weakness, bowel or bladder changes, rapidly worsening neurological symptoms, or signs of a significant infection require prompt medical attention. For painful or unexpected stimulation, contact your treating specialist and follow the device instructions for reducing or stopping stimulation when appropriate. Do not arrange removal surgery just because you saw a recall announcement.

Tell your doctor about the symptoms and ask that the device be evaluated. You or your clinician may also report suspected medical device problems to the FDA. Once the medical issues are addressed, preserve the records and communications that may help explain what occurred.

Boston Scientific Spinal Cord Stimulator Lawsuit FAQs

Is there a Boston Scientific spinal cord stimulator class action lawsuit?

There is a federal multidistrict litigation, MDL 3181, that coordinates related individual lawsuits. It is not a class action that awards the same amount to everyone. Each plaintiff has an individual claim and must prove individual injuries and damages.

Has Boston Scientific agreed to a spinal cord stimulator settlement?

No global Boston Scientific MDL settlement has been announced as of November 5, 2026. The settlement ranges on this page are preliminary estimates developed by our lawyers, not established payouts.

Was the Boston Scientific Infinion CX lead recalled?

Yes. The FDA classified the 2026 removal of unused Infinion CX lead kit models SC-2317-50 and SC-2317-70 as a Class I recall. The issue involves possible lead fracture or high impedance. The FDA did not recommend removal of leads already implanted solely because of this action.

Was the WaveWriter Alpha spinal cord stimulator recalled?

Certain WaveWriter Alpha generators, models SC-1216 and SC-1232 within specified serial ranges, were involved in a 2024 FDA Class II recall. Charging could trigger a brief reset and interruption of stimulation. Boston Scientific made a firmware update available to address the problem.

Can I sue if my Boston Scientific device was never recalled?

Possibly. A recall is useful evidence, but an individual case turns on the device, the alleged failure, the medical injury, and the applicable law. We evaluate serious problems even when the device model was not part of a particular recall.

What if repeated reprogramming never fixed my stimulator?

That history can be important, particularly where the patient also experienced painful shocks, lead problems, or later revision surgery. We want to review the programming logs and records showing what the patient reported before and after each adjustment.

Does FDA approval protect Boston Scientific from all lawsuits?

No, but federal preemption is a major defense for Class III devices approved through the FDA premarket approval process. Plaintiffs need legally viable claims supported by evidence of a violation or other actionable conduct under the applicable federal and state law framework.

How long do I have to file a Boston Scientific lawsuit?

Deadlines depend on state law, injury dates, discovery of the problem, and other facts. A revision or removal procedure does not necessarily restart the filing period. Our firm has additional intake screening for one-year limitations periods and deadlines within six months.

Talk to Our Lawyers About a Boston Scientific Spinal Cord Stimulator Injury

What happened after the implantation? Did the trial work and the permanent device fail? Were you shocked or burned? Did somebody keep adjusting the settings while your condition got worse? Did you need another surgery, or were you left with lasting weakness or another serious neurological problem?

Those are the questions we want to ask. We also want the records, because the most persuasive version of a patient’s story is the one in which the medical evidence and the timeline support what the patient has been saying all along.

Our lawyers are reviewing selected Boston Scientific claims involving serious injury, hardware failure, lead migration, revision or explant surgery, severe infection, and permanent neurological harm. We can evaluate whether the facts support a product liability claim and what steps would be involved in pursuing compensation.
