CYBERONICS, INC. LEAD MODEL 302 Back to Search Results
Model Number 302-20
Event Date 08/11/2014
Event Type  Malfunction  
Event Description

Analysis of the returned lead portion was completed which confirmed discontinuity of negative quadfilar coil in the body region. Scanning electron microscopy images of the negative coil show that pitting or electro-etching conditions have occurred at the break location. Abraded openings were observed on both the outer and inner tubing near the break location. The lead assembly has dried remnants of what appear to have once been body fluids inside the inner and outer silicone tubing. No obvious point of entrance was noted other than the identified tubing opening and the cut end of the returned lead portion. Incisions in the silicone tubing of the lead were necessary to perform proper inspection of the lead coils.

Manufacturer Narrative

Device failure occurred, but did not cause or contribute to death or serious injury.

Diagnostic results showed lead impedance within normal limits prior to surgery and high impedance was first observed during the procedure. The surgeon elected the replace the patient¿s lead and stated that the explanted lead was kinked. The explanted generator and lead have not been returned to date.
