CYBERONICS, INC. LEAD MODEL 302 Back to Search Results
Model Number 302-20
Device Problem Battery Impedance Issue
Event Date 05/01/2009
Event Type  Malfunction  
Event Description

Reporter indicated that high lead impedance readings were obtained during a follow up office visit following a generator revision surgery. The physician indicated that the pt did not have issues with high lead impedance prior to the date of the report and the diagnostic testing performed twice resulted in high lead impedance. Add'l info received from a company representative who was present during the generator revision surgery revealed that diagnostics were performed on the newly implanted generator and stated that high lead impedance readings were initially received; however, once the connector pin was reinserted the high lead impedance readings resolved. X-rays were taken and sent to the manufacturer for analysis; however, the quality of the images was not ideal. No anomalies were observed; however, the entire lead could not be viewed. This info was shared with the physician's office. It is likely that the pt will undergo revision or exploratory surgery to further investigate the issue; however, no date has been set.

Manufacturer Narrative

Manufacturer reviewed x-rays of implanted device. X-rays reviewed by the manufacturer, no gross lead discontinuities visualized. Device failure is suspected, but did not cause or contribute to a death or serious injury.
