The U.S. Food and Drug Administration (FDA) has issued an Early Alert regarding certain Boston Scientific ENROUTE Transcarotid Neuroprotection System (NPS) and ENROUTE Transcarotid Neuroprotection System Plus (NPS Plus) devices after reports that the arterial sheath tip can separate or partially separate during use. Because these devices are used during procedures involving the carotid arteries, a device failure may expose patients to life-threatening complications, including stroke, embolism, thrombosis, and the need for emergency surgical intervention.
Unlike many recalls involving consumer products, this alert concerns a sophisticated medical device used during procedures intended to reduce the risk of stroke in patients with carotid artery disease. Patients undergoing these procedures are already facing serious cardiovascular conditions. A malfunction occurring inside a major blood vessel can transform a carefully planned treatment into a medical emergency requiring immediate action.
Boston Scientific has instructed healthcare facilities to stop using the affected products immediately, remove them from inventory, and return them to the company. The FDA continues to evaluate the issue and has indicated it will provide additional updates as more information becomes available.
Medical device failures involving vascular systems can have devastating consequences. Even when patients survive the initial complication, they may experience permanent neurological injuries, prolonged hospitalization, additional surgeries, rehabilitation, and significant financial losses. For patients and families affected by this issue, understanding the nature of the device, the reported defect, and potential legal rights is an important first step.
The FDA’s Early Alert involves specific lots of two medical devices manufactured by Boston Scientific:
These systems are used during transcarotid artery revascularization (TCAR) procedures. Rather than functioning as permanent implants, these devices help physicians perform minimally invasive treatment of carotid artery disease while attempting to reduce the risk of debris traveling to the brain.
Boston Scientific notified customers on July 9, 2026, recommending immediate removal of affected products from use. Hospitals, surgery centers, and medical facilities were instructed to:
These actions reflect the seriousness of the reported device issue and the potential consequences if an affected catheter is used during a patient procedure.
The ENROUTE Transcarotid Neuroprotection System is designed to reduce the risk of stroke during treatment of carotid artery disease.
Carotid arteries deliver oxygen-rich blood from the heart to the brain. When plaque builds inside these arteries, patients face an increased risk of stroke because plaque fragments or blood clots may travel to the brain and block blood flow.
During carotid artery procedures, physicians manipulate plaques and narrowed blood vessels. This process can release tiny particles known as emboli.
The ENROUTE system works by temporarily reversing blood flow away from the brain during portions of the procedure. By redirecting blood flow, the system is intended to capture or divert embolic material before it reaches the brain.
Because these devices function inside major blood vessels supplying the brain, their structural integrity is critical. Any component failure occurring inside an artery can immediately create additional risks beyond the patient’s underlying vascular disease.
According to Boston Scientific, the affected devices may experience arterial sheath tip separation or partial tip separation during use.
This means part of the catheter tip may detach while inside a patient’s blood vessel.
When a foreign object separates inside an artery, physicians must determine how to retrieve it safely. Retrieval may require additional endovascular procedures or open surgery. Both options expose patients to increased procedural risks.
A retained catheter fragment can also interfere with normal blood flow or become a source of dangerous complications.
Potential complications identified by Boston Scientific include:
Each of these complications carries the potential for permanent injury.
A stroke occurs when blood flow to part of the brain becomes interrupted. Brain cells deprived of oxygen begin dying within minutes. Depending upon the affected brain region, patients may experience paralysis, speech impairment, cognitive deficits, vision loss, memory problems, or death.
An embolism occurs when material traveling through the bloodstream blocks a blood vessel. A detached catheter fragment or clot may obstruct circulation to the brain or other organs.
Often referred to as a “mini-stroke,” a transient ischemic attack temporarily interrupts blood flow to the brain. Although symptoms may resolve, TIAs significantly increase the future risk of a major stroke.
Restenosis refers to the re-narrowing of a treated blood vessel. Additional interventions may become necessary if adequate blood flow cannot be maintained.
Blood clots forming around retained catheter fragments or damaged blood vessels can obstruct circulation and increase the risk of stroke or tissue injury.
One of the most concerning aspects of this device issue is that separated catheter tips may require retrieval.
Retrieving a foreign object from inside an artery is rarely straightforward.
Depending on the location of the retained fragment, physicians may attempt minimally invasive retrieval using specialized instruments inserted through blood vessels. If these efforts fail, open vascular surgery may become necessary.
Additional procedures increase exposure to:
Patients who entered the hospital expecting a planned vascular procedure may suddenly face a far more complicated medical situation because of device failure.
Unlike finalized recalls, FDA Early Alerts notify healthcare providers and the public when regulators believe a potentially high-risk medical device issue requires immediate attention.
These alerts provide important information while the FDA continues evaluating available evidence.
In this case, the FDA is advising healthcare providers not to use affected products while additional review continues.
As of July 9, 2026, Boston Scientific reported:
The absence of reported deaths should not be interpreted as evidence that the device issue is minor. Serious vascular complications can permanently alter a patient’s quality of life even when they survive.
Early warnings often allow hospitals to prevent additional injuries before broader corrective actions are completed.
Medical device manufacturers have a responsibility to design, manufacture, test, and monitor products intended for patient care.
When devices allegedly fail during normal use, injured patients may pursue legal claims depending upon the specific facts.
Potential legal theories may include:
If the catheter tip design created an unreasonable risk of separation during ordinary use, injured patients may allege the device contained a design defect.
Some failures occur because of production errors affecting certain manufacturing lots rather than the overall product design.
Manufacturers must provide physicians with appropriate warnings regarding known risks associated with medical devices. If information concerning potential failures was incomplete or delayed, that issue may become part of later litigation.
Investigations frequently examine product development, testing, quality control, post-market surveillance, complaint investigations, and the manufacturer’s response after learning of potential safety issues.
Medical device litigation often requires extensive review of engineering records, regulatory submissions, manufacturing documentation, adverse event reports, physician testimony, and expert medical analysis.
A catheter failure during a carotid artery procedure can create lasting consequences extending well beyond the operating room.
Depending upon the complication, patients may require:
Serious neurological injuries may interfere with employment, independence, driving, and daily activities.
Families often experience significant emotional and financial burdens while helping loved ones recover from permanent disabilities.
Compensation in medical device cases may include medical expenses, future treatment costs, lost income, diminished earning capacity, pain and suffering, permanent disability, rehabilitation expenses, and other legally recoverable damages.
Patients should not assume that every procedure involving an ENROUTE system resulted in a device failure.
However, individuals who underwent transcarotid artery revascularization procedures during the affected timeframe may wish to discuss the issue with their treating physician.
Patients experiencing new neurological symptoms, unexplained complications, or unexpected follow-up procedures should seek prompt medical evaluation.
Medical records identifying the specific device used during treatment may become important if questions later arise concerning affected product lots.
Patients should not discontinue prescribed medical care without guidance from their healthcare providers.
Possibly. If medical evidence indicates that catheter tip separation or another device malfunction contributed to your stroke or other complications, you may have grounds to pursue a product liability claim. Every case requires an individual review of medical records, imaging studies, operative reports, and other evidence to determine whether the device played a role in your injuries.
Patients may have legal claims if they experienced complications such as stroke, embolism, thrombosis, transient ischemic attack, emergency vascular surgery, prolonged hospitalization, neurological injury, or other serious medical problems allegedly connected to a defective medical device. The specific circumstances surrounding the procedure and resulting injuries are important when evaluating a claim.
An FDA Early Alert is intended to notify healthcare providers and the public about a potentially high-risk device issue while the agency continues its evaluation. In this situation, Boston Scientific instructed customers to stop using affected devices and return them. The FDA continues reviewing the matter and may issue additional updates as more information becomes available.
Depending on the facts of the case, compensation may include medical expenses, future healthcare costs, rehabilitation, lost wages, diminished earning capacity, pain and suffering, permanent disability, and other damages recognized under applicable law. Families may also have legal rights if a patient dies from complications related to an allegedly defective medical device.
Your hospital or treating physician should have records identifying the medical devices used during your procedure. Operative reports, implant logs, and hospital records often contain product names, lot numbers, and other identifying information that may help determine whether an affected device was involved.
Patients should keep copies of medical records, hospital discharge summaries, imaging studies, operative reports, follow-up treatment records, insurance information, prescription records, and documentation showing lost income or additional expenses. This information may assist attorneys and medical professionals evaluating a potential claim.
Patients trust medical devices used during vascular procedures to function safely and reliably. When an alleged device defect results in a stroke, emergency surgery, or other serious complications, the physical, emotional, and financial consequences can be overwhelming.
