CYBERONICS, INC. LEAD MODEL 302 Back to Search Results
Model Number 302-20
Event Date 03/29/2010
Event Type  Malfunction  
Event Description

It was initially reported that diagnostics performed indicated that high lead impedance was present, but specifics were not available. It was also mentioned by the parent that the magnet activations were no longer being perceived for approx two months prior. The pt's seizures were also said to be "different", but no further details have been made on the issue. X-rays were taken and sent to the mfr for analysis. No gross lead fractures or discontinuities were visualized on the portions of the lead body that could be assessed. However, the image quality in the neck area was poor, and there was a portion of the lead body located behind the generator that could not be assessed. Based on the x-rays received, there were no gross lead discontinuities or anomalies observed that could be contributing to the high lead impedance event. However, a led discontinuity cannot be ruled out on the portions of the lead that could not be fully assessed. Good faith attempts to obtain additional info have been unsuccessful to date. A review of the mfr's programming history database indicated that the last known diagnostics were within normal limits.
