CYBERONICS, INC. BIPOL LEAD MODEL 300 Back to Search Results
Model Number 300-20
Event Date 01/01/2009
Event Type  Malfunction  
Event Description

Reporter indicated that the pt was in the hosp due to a fluid build-up around his generator. The pt had both the generator and lead removed. During the procedure, what appeared to be pus was found inside of the lead, and the negative electrode had "disintegrated" as per the company representative's account. During the procedure, cultures of the site were taken and were negative for an infection, but the surgeon still believed that the fluid build-up could be due to an infection that started during the pt's previous prophylactic generator replacement surgery, as the pt had been on multiple antibiotics since the beginning of the hospitalization. During the removal procedure, it was noted that there were metallic bits within the fluid that was surrounding the generator. Attempts for more info were unsuccessful. The lead has been returned to the manufacturer, along with the metallic bits found in the fluid surrounding the generator, for analysis, but analysis has not yet been completed.

Manufacturer Narrative

Device manufacturing records were reviewed. Review of manufacturing records confirmed sterilization of both the generator and lead prior to distribution. Device failure suspected.
