VNS Therapy, SenTiva, Model # 1000, (01)05425025750405, Rx Only for vagal nerve stimulation (VNS) therapy

Sentiva generators may reset and become disabled within 60 days of enabling. Physicians can re-enable but devices will continue to be susceptible to resets. If a device experiences this issue, this may lead to additional surgery (premature replacement of generator), or patients may return to baseline seizure frequency or depressive symptoms due to cessation of intended stimulation.

On 08/22/19, Urgent Medical Device Correction notices were sent to customers including Neurosurgery, Risk Management, Neurology, and doctors. Doctors were asked to do the following: 1) Monitor the patient frequently and continue to perform diagnostic testing at each visit per labeling. Information and recommendations regarding device checks, resets and monitoring of clinical symptoms can be accessed in the physician's manual. 2) If the initial interrogation of the generator is found to be disabled unexpectedly (0mA output current), contact Customer Quality at (866) 882-8804 (Monday to Friday, 8 AM to 5 PM CST) or e-mail at [email protected]. 3) Ensure the patient does the following: a. (Epilepsy only) For patients that are able to do so and have Magnet Mode enabled, continue using their magnet regularly to verify that stimulation is felt as described by the labeling; and b. Notify their physician if there is a change in perceived clinical symptoms (e.g., increase in seizures/depressive symptoms, loss of perception of stimulation, etc.). 4) Please complete and return the attached Customer Response Form. Please return all potentially affected devices that remain in the hospital/facility inventory to the recalling firm. Further, a device update to resolve the issue in patient's devices is currently under development. The recalling firm will contact you as more information becomes available regarding this update.
