CYBERONICS, INC. LEAD MODEL 302 Back to Search Results
Model Number 302-20
Event Date 06/28/2011
Event Type  Malfunction  
Event Description

The patient had full revision surgery on (b)(6) 2013, and their explanted products have at this time not been returned for analysis.

Event Description

The explanted generator and lead will not be returned for analysis.

Event Description

It was reported that the patient's vns is indicating high lead impedance. The physician believes the vns may have been damaged during cardiac surgery for valve replacement and aneurysm repair on (b)(6) 2011. However, the vns had not been checked since (b)(6) 2011. Both of the cardiac events are reportedly not related to vns therapy. Attempts for additional information have been unsuccessful to date. Surgery to replace the vns lead and generator is likely. No adverse events have been reported.

Manufacturer Narrative

Device failure is suspected but did not cause or contribute to a death or serious injury.

Event Description

Additional information was received indicating no x-rays were taken to evaluate for a lead fracture. The physician confirmed that the high impedance is believed to be a result of damage incurred during open heart surgery. The patient has had increased seizures since the time of the surgery that was originally believed to be related to the surgery however the increased seizures did not resolve after some time leading to the physician suspecting an issue. The seizures were noted as slightly improved following surgery and the overall increased seizure frequency was noted as being below the pre-vns baseline. The physician disabled the patient's vns when the high impedance was discovered on (b)(6) 2012.
