CYBERONICS, INC. LEAD MODEL 302 Back to Search Results
Model Number 302-20
Event Date 12/23/2014
Event Type  Malfunction  
Event Description

It was reported that the patient was referred for generator and lead replacement due to high impedance. X-rays were taken, but did not reveal any lead discontinuities. It is unknown if any patient manipulation or trauma occurred that may have caused or contributed to the high impedance. No known surgical interventions have been performed to date.

Manufacturer Narrative

Device failure is suspected, but did not cause or contribute to a death or serious injury.

Event Description

Additional information was received stating that the vns patient underwent generator and lead replacement surgery on (b)(6) 2015 due to lead discontinuity. The explanted devices were returned to the manufacturer for analysis. No abnormal performance or any other type of adverse condition was found with the returned pulse generator. The device performed according to functional specifications. Analysis of the returned lead confirmed discontinuity of positive quadfilar coil in the body region of the returned lead portions. Scanning electron microscopy images of the positive coil show that pitting or electro-etching conditions have occurred at the suspected broken end of the coil. However, due to metal dissolution, a conclusive determination of the fracture mechanism of the coil cannot be made. Though it is difficult to state conclusively the most likely cause for the observed pitting condition is that the generator was not programmed off at the time of explant. The lead assembly has punctures in the outer silicone tubing and the inner tubing. The lead assembly has dried remnants of what appear to have once been body fluids inside the inner and the outer silicone tubing. No obvious point of entrance was noted other than the identified tubing openings and the end of the returned lead portion.

Manufacturer Narrative

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