Nevro Spinal Cord Stimulator Lawsuits

The Spinal Cord Stimulator Lawsuit Is An Active Lawsuit

See If You Qualify

Nevro spinal cord stimulator lawsuits claim that some patients who had Senza, Senza Omnia, or Senza HFX iQ spinal cord stimulators implanted experienced serious complications. Problems listed in Nevro spinal cord stimulator lawsuits include device failures, infections, lead migration, lead malfunction, nerve damage, failed pain relief, and improper device programming. Some lawsuits also claim that Nevro developed new spinal cord stimulator devices by changing the originally FDA-approved device more than 60 times. According to the complaints, those changes effectively created new versions of the device and may have compromised patient safety.

About the Nevro Spinal Cord Stimulator Lawsuits

Fast Facts About Nevro Spinal Cord Stimulators & Lawsuits

Which Nevro Spinal Cord Stimulator Devices Are Involved in Lawsuits?

Nevro spinal cord stimulators that have been named in lawsuits include the following:

• Senza
• HFX iQ
• HFX Trial
• Omnia
• Senza II

As more cases are filed, patients may include different Nevro spinal cord stimulators in their legal complaints. Not every Nevro device is defective just because it has been part of a lawsuit.

How Are Nevro’s Spinal Cord Stimulators Different From Other Manufacturers’ Devices?

Nevro’s spinal cord stimulators rely on a technology called HF10™ therapy. Some patients choose Nevro’s SCS devices because they are different from many of the other SCS devices on the market. Using HF10™, patients may be able to avoid paresthesias, which are stimulation-induced sensations that include tingling or pins-and-needles. According to Nevro, its SCS technology has been confirmed by the FDA to be superior to traditional SCS therapy , which is delivered at a much lower frequency. Nevro has said its devices have “paresthesia-free indication from the FDA” and “an equivalent safety profile to traditional SCS therapy.”

How HF10™ Therapy May Be Relevant in Nevro SCS Lawsuits

Because of the claims made around the HF10™ technology, some patients may have felt that Nevro’s devices would provide a higher level of care with fewer side effects. However, even if patients experienced fewer paresthesias, they may still have experienced other severe side effects, similar to those patients with other brands of spinal cord stimulators.

Nevro Spinal Cord Stimulator Side Effects

Spinal cord stimulators made by Nevro have known risks and side effects, just like any medical device. The patient manual for the Senza, Senza II, and Omnia spinal cord stimulator warns about the following potential side effects:

• Battery overheating during charging
• Interference with MRIs, CT scans, and other imaging
• Lead overheating during some medical procedures
• Tingling sensations from certain settings
• Lead migration due to the patient moving suddenly or sharply
• Infection
• Device failure
• Tenderness at the site of implantation
• Paralysis
• Death
• Loss of pain relief or increase in pain
• Jolting or shocking sensations
• Weakness
• Numbness
• Allergic reaction to what the device is made of
• Lead fracture
• Pressure sores

The manual lists other types of side effects (adverse events) that some patients could experience with these Nevro SCS devices.

The HFX iQ spinal cord stimulator manual given to patients does not list adverse events . Instead, the manual tells patients that they can learn about side effects by asking their doctors for a copy of the Nevro spinal cord stimulator manual that Nevro made for doctors. The Nevro spinal cord stimulator manual given to doctors includes the following on the list of side effects from the implant surgery or device:

• Infections
• Paralysis
• Death
• Lead migration (read more about signs of SCS lead migration)
• Loss of pain relief
• Electrocution
• Undesirable sensations
• Worsening pain
• Allergic reaction to device materials
• Lead fracture

Some patients who had the Nevro spinal cord stimulator implanted say they were not properly warned about these potential side effects or that Nevro representatives made them believe these events were much less common than they are.

What Problems Have Been Reported for Nevro Spinal Cord Stimulators?

People with Nevro SCS devices have reported multiple injuries to their doctors and the FDA. Some of the problems reported by people with Nevro spinal cord stimulators include:

• Infection or pain at the incision site
• Burns
• SCS lead migration or fracture
• New or worsening pain
• Inconsistent or inadequate pain relief
• New mobility issues

Some of these issues necessitate an SCS removal (explant) or replacement (revision) surgery, which comes with risks. Some patients’ injuries were not fully remedied by device removal.

The FDA tracks medical device adverse event reports in the Manufacturer and User Facility Device Experience (MAUDE) Database (MAUDE). MAUDE reports about Nevro SCS devices are relatively common. For example, according to a MAUDE database search, there were 48 adverse event reports submitted for Nevro’s Senza SCS devices between June 1, 2026, and June 30, 2026.

Injuries Listed in Adverse Event Reports for Nevro SCS Devices

According to the MAUDE database, injuries that have been reported with the Nevro SCS systems on MAUDE include infections, device malfunction, worsening pain, numbness, tingling, lead migration, and burning sensations.

Here are some of the reports and associated injuries for Nevro SCSs reported via MedWatch and recorded in the MAUDE database.

*It is important to note that reported injuries have many causes, including patient error, doctor error, device malfunctions, or other causes. The MAUDE database may include reports that have not been investigated or verified. So, not all issues reported to MAUDE are due to how the Nevro spinal cord stimulator device was implanted, designed, or reprogrammed.

How Can Nevro Patients Find Medical Device Safety Reports About Their SCS Device?

If a patient experienced a severe side effect after having a Nevro SCS implanted, they can submit an FDA safety report through MedWatch. Patients can also search for MAUDE reports about their Nevro spinal cord stimulator devices by entering “Nevro” in the manufacturer field and the model of their SCS in the “Brand Name” field.

Have Nevro Spinal Cord Stimulators Been Recalled?

Nevro spinal cord stimulator devices have not been recalled. Nevro has not issued broad safety notices about its spinal cord stimulators, either. However, patients and medical providers have submitted numerous adverse event reports in the MAUDE database. Nevro may issue recalls or safety notices in the future.

What Are the Allegations Against Nevro?

Here are some of the allegations against Nevro because of its spinal cord stimulator devices or the conduct of its representatives:

• Legal complaints say that Nevro allegedly used the FDA’s PMA supplement process to update the firmware, batteries, leads, and other features of its original Senza spinal cord stimulator device, and then used those updates to create new models (such as the Senza, which was rebranded as the Omnia model) without going through the pre-market approval process for those models.
• Legal complaints claim that the Nevro spinal cord stimulator devices have a high rate of lead failure and malfunction, which may cause stimulation to be too high or to reach unintended areas of the body.
• Patients have also accused Nevro representatives of misleading patients about the risks and potential benefits of the spinal cord stimulator device.
• Nevro spinal cord stimulator patients have also alleged that Nevro representatives engaged in the unauthorized practice of medicine by attending or assisting in patient surgeries, reprogramming devices, giving patients medical advice, and other misconduct.
• Nevro SCS patients have also said they should have been told that the external trial version of the Nevro spinal cord stimulator does not work as well or the same way as the fully implantable version. Many patients say they experienced pain relief and minimal symptoms from the trial version of the Nevro device, but they had a much different experience when they had the permanent spinal cord stimulator device implanted.

Examples of Lawsuits Against Nevro

Here are examples of lawsuits that have been filed against Nevro:

• One patient claimed the Nevro spinal cord stimulator device caused overstimulation and nerve damage.
• A Nevro spinal cord stimulator patient alleged that they experienced numbness, worsening pain, weakness, blood clots, and an inability to control their bladder after having the device implanted.
• A patient says they suffered from weakness, pain, shocking sensations, and the death of bone tissue in their thigh bones because of the Nevro spinal cord stimulator device.
• Another Nevro patient alleges that they suffered from unexpected blood blots, new and worsening pain, weakness in extremities, pressure ulcers, and trouble swallowing after having the device implanted.
• A patient claims they had a Nevro spinal cord stimulator device implanted and sustained nerve damage, weakness, and other complications due to the device and lead malfunctioning.

Nevro’s Response to Lawsuits and Allegations

According to court records, Nevro has denied wrongdoing and filed documents to dismiss some of the legal complaints against it. Nevro has also claimed that it gave patients proper warnings about the potential side effects of spinal cord stimulator devices. It also contends that it has followed all FDA requirements for PMA supplements, use of non-physician representatives, and medical device labeling.
