CYBERONICS, INC. PULSE GEN MODEL 103 Back to Search Results
Model Number 103
Event Date 08/17/2012
Event Type  Injury  
Event Description

The patient's explanting surgeon reported to the patient's mother that at the time of explant it was noted that there was a lot of scarring and thin, loose skin around the device, probably causing the patient to feel some pain since not enough fat to insulate the device. The patient did not report any pain events prior to their explant event. Prior to explant in (b)(6) 2012, the patient was having coughing and dysphagia with stimulation. The patient's surgeon reported that their explant was more related to a rejection to the implanted products not an infection. It was reported that the vns seemed to reduce the patient's seizures as was reported to have had only 1 big seizure (b)(6) 2012. The patient was having seizures again since their device was explanted. No further information has been received at this time.

Event Description

Additional information was received. The patient's surgeon reported that their explant was more related to a rejection to the implanted products, not an infection. It is possible that picking at the wound led to the eventual dehiscence, but the exuberant tissue overgrowth was likely the main problem and not related to the trauma or manipulation. Cultures were taken from the neck incision when the vns was explanted on (b)(6) 2012. They grew out staph aureas. The patient was treated with antibiotics starting (b)(6) 2012 and the extruded neck lead was reimplanted after re-exploration and thorough irrigation on (b)(6) 2012. Their infection has resolved. At this time they do not plan to re-implant it since i believe the patient's hypertrophic reaction is a rejection to the device material.

Event Description

A vns patient reported that they had their generator and lead explanted for an infection at the electrode site. The family wants device replaced if possible once their infection heals. Thus far no further information has been attained.

Manufacturer Narrative
