CYBERONICS, INC. LEAD MODEL 302 Back to Search Results
Model Number 302-20
Event Date 11/20/2009
Event Type  Malfunction  
Event Description

It was reported that high lead impedance readings were obtained during generator revision surgery when the new generator was connected to the existing lead. Upon observation of the lead body, the surgeon noted a clean cut in the silicone tubing directly above the generator pocket. The old leads were cut at the midpoint due to excessive scar tissue around the nerve. A new lead was not implanted at that time due to the scar tissue. No x-rays were taken prior to surgery and there were no reports of pt manipulation or trauma that could have caused or contributed to the reported event. A new lead was implanted on the right vagus nerve at a later date and the high lead impedance readings resolved. The explanted lead has been returned to the mfr and device eval is in process.
