CYBERONICS, INC. LEAD MODEL 302 Back to Search Results
Model Number 302-30
Event Date 02/06/2015
Event Type  Malfunction  
Event Description

It was reported that device diagnostics resulted in high impedance (dc dc code - 7). The patient was referred for surgery. The patient underwent generator and lead replacement due to high impedance and end of service. The explanted generator and lead were received for analysis. Analysis is underway, but has not been completed to date.

Event Description

Analysis of the explanted devices was completed. The end of service condition of the generator was determined to be the result of normal battery depletion. There was no condition noted during the analysis that would suggest any anomaly with the device. Analysis of the returned lead portions confirmed discontinuity of positive quadfilar coil in the electrode region. Pitting and flat spots were observed on the coil surface on both sides of this lead discontinuity.
