Manufacturer Reason
for Recall		 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.
