CYBERONICS, INC. LEAD MODEL 302 Back to Search Results
Model Number 302-20
Event Date 01/01/2013
Event Type  Malfunction  
Event Description

It was reported that the patient was having the vns generator and lead explanted due to the generator being at end of service since 2014 and the patient being a non-responder when the generator was on. The explanted generator and lead were returned for product analysis. Product analysis on the generator found that it was at end of service and could not be communicated with. The battery's voltage was 0. 6v, the generator will no longer communicate after the battery reaches 1. 8v. Product analysis on the lead identified fractures of the quadfilar coils and abraded openings of the outer and inner tubings. It was also noted that the quadfilar coil had signs of pitting which appeared to be the result of stimulation being provided after the fracture had occurred. Review of the internal programming history database contained data up until (b)(6) 2012 where diagnostic results were within normal limits. Therefore it is known that the lead fracture occurred after (b)(6) 2012. Due to the pitting that was observed it is likely that the fracture occurred prior to the generator's end of service condition.
