Abbott Spinal Cord Stimulator Lawsuit Alleges Defects Caused Lead Migration, Electric Shocks

Abbott Spinal Cord Stimulator Lawsuit Lead Migration, Electric Shocks, Incontinence

Three women have filed a joint lawsuit indicating they suffered serious injuries from defective Abbott spinal cord stimulator systems, indicating that the manufacturer misrepresented the safety of the devices and risk they may pose to the health of patients.

The complaint (PDF) was filed by Dorothy Furia of California, Roseann Maroulis of Indiana and Anita McClellan of Oklahoma in the U.S. District Court for the Northern District of California on March 5. The lawsuit names both Abbott Laboratories and the U.S. Food and Drug Administration (FDA) as defendants.

All three plaintiffs were implanted with an Abbott Spinal Cord Stimulator, a medical device surgically placed in patients suffering from severe, chronic back pain. The system works by delivering electrical pulses to the spinal cord, which are intended to interrupt pain signals before they reach the brain.

The implant is designed to remain permanently inside the patientโ€™s body. Each system includes a small battery powered pulse generator implanted beneath the skin, thin electrical leads positioned along the spinal cord, and an external controller that allows physicians or patients to adjust the level of stimulation.

Spinal Cord Stimulator Injuries

First introduced in the early 2000s, manufacturers have continued to refine and revamp the design of SCS devices, releasing multiple updated versions. Many of those updated versions were approved through the FDAโ€™s 510(k) fast-track approval process, allowing devices to be approved without full clinical trials as long as they are deemed โ€œsubstantially equivalentโ€ to previous existing models.

The program has faced significant criticism over the years due to vague and inconsistent interpretations of what qualifies as โ€œsubstantially equivalent.โ€ Critics argue the FDA often takes a lenient approach and does not adequately verify whether newer devices include major changes in operation, materials or other design features compared to the original product.

Plaintiffs in a growing number of spinal cord stimulator lawsuits say SCS devices have undergone significant design and programming changes with limited independent testing. They report incidents involving sudden electrical shocks, burning sensations, worsening pain, neurological problems, lead fractures and lead migrations, and ineffective pain relief. In some cases the patients have to undergo revision or removal surgeries.

All three plaintiffs in this latest lawsuit experienced similar complications and injuries after being implanted with the Abbott Proclaim XR SCS, both related to the design of the implant and the actions of Abbottโ€™s sales representatives. In addition, all three say the FDA should have prevented the device from hitting the market without adequate testing.

Electric Shocks and Bladder Incontinence

Furia was implanted with an Abbott Eterna SCS in 2024 after being told by Abbott sales representatives that the implant would relieve most of her back pain. 

Instead, she indicates the device not only gave minimal pain relief but also caused her to suffer bladder incontinence and electric shocks.

Revision Surgery After Leads Protrude Through Skin

In the case of Maroulis, she first underwent a routine trial implantation of an Abbott spinal cord stimulator in January 2023. These temporary test implants are commonly used to determine whether the therapy provides sufficient pain relief before surgeons proceed with a permanent device.

After the short trial period, the temporary device was removed and Maroulis received a permanent spinal cord stimulator implant in March. However, less than two months later she required revision surgery after discovering the deviceโ€™s electrical leads were protruding through her skin. When the revision procedure failed to correct the problem, doctors ultimately removed the spinal cord stimulator entirely.

Nerve Damage, Electric Shocks and Worsening Pain

The third plaintiff, McClellan also says she was first implanted with a trial device before receiving the permanent version in June 2021. However, she indicates that the trial device was more effective at preventing pain than the permanent one.

McClellan suffered numbness, loss of feeling in extremities, bladder incontinence, electric shocks, burning sensations around the implant and worsening pain. While the device was removed due to health complications, McClellan reports still suffering pain and symptoms that may have been worsened by the failed device.

All three plaintiffs indicate that there was heavy involvement of Abbott sales representatives, who often met with patients outside of the presence of their doctors, and made adjustments to the programming of the devices without proper medical training.

The women present claims of manufacturing defect, failure to warn, negligence per se, breach of warranty, negligence, negligent misrepresentation, fraudulent concealment, violation of consumer protection laws, unauthorized practice of medicine, and a claim of violations of the Administrative Procedure Act against the FDA.

SCS Injury Lawsuits

Last month, a group of plaintiffs filed a motion to transfer with the U.S. Judicial Panel on Multidistrict Litigation (JPML), calling for all SCS injury lawsuits to be consolidated into a multidistrict litigation, or MDL, in the Northern District of Illinois for coordinated discovery and pretrial proceedings.

To date, spinal cord stimulator lawsuits have been filed against Abbott, Boston Scientific and Medtronic, who all have SCS models on the market. Litigation is expected to grow against those companies and other SCS manufacturers for individuals who suffered injuries such as:

  • Lead wire fracture or migration
  • Electrical shocks or overstimulation
  • Sudden loss of pain relief
  • Worsening chronic back or nerve pain
  • Revision surgery or device removal
  • Permanent nerve damage
  • Long-term spinal cord complications

All spinal cord stimulator injury lawsuits are handled on a contingency-fee basis, meaning there are no upfront costs, and attorney fees are only paid if compensation is obtained through a settlement or trial verdict.
