CYBERONICS, INC. LEAD MODEL 302 Back to Search Results
Model Number 302-20
Event Date 09/29/2014
Event Type  Malfunction  
Event Description

It was reported that device diagnostics resulted in high impedance (dc dc code - 7). The patient was referred to neurosurgery. No additional relevant information has been received to date.

Manufacturer Narrative

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

Event Description

It was reported that during surgery device diagnostics showed high impedance with the new generator attached to the existing lead. The generator was tested with the test resister which showed the generator was within normal limits. The surgeon then dissected the lead coils off of the nerve and placed a new lead. An implant card was received confirming that both the generator and lead were replaced and that lead impedance with the new system was within normal limits. The explanted lead was received for analysis. Analysis of the lead was completed on (b)(4) 2014. A break was identified in the positive coil. Scanning electron microscopy images of the positive coil broken ends show that pitting or electro-etching conditions have occurred at the break location. However, due to metal dissolution and surface contamination the fracture mechanism cannot be determined. Other than the above mentioned observations and typical wear and explant related observations, no other anomalies were identified in the returned lead portion.

Manufacturer Narrative

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