CYBERONICS, INC. LEAD MODEL 302 Back to Search Results
Model Number 302-20
Event Date 03/01/2010
Event Type  Malfunction  
Event Description

It was initially reported by the surgeon that the pt was taken into surgery for battery replacement due to end-of-service (eos). Surgeon also indicated that the device was turned off as pt was experiencing stabbing pain at the generator site. When pt was taken into surgery, preop diagnostics on the device showed high lead impedance and not eos. Diagnostics were performed twice and same results were obtained. The surgeon decided to replace the generator and the lead. Pt's neck was opened and the surgeon was able to visualize a complete lead break near the bifurcation of the old lead. New generator and lead were placed in the pt and post-op diagnostics showed everything working within normal limits. The surgeon accidentally nicked the left intra-jugular vein during surgery. A vascular surgeon was called to repair the vein and pt was closed up. No x-rays were taken prior to the surgery. Painful stimulation at the generator is likely related to the high lead impedance. Good faith attempts to obtain add'l info has been unsuccessful.
