CYBERONICS INC LEAD MODEL 303 Back to Search Results
Model Number 303-20
Event Date 08/29/2011
Event Type  Malfunction  
Event Description

Additional information was received that the patient went for a lead revision but it was unable to be completed due to adhesions. The office was unsure if the lead was left connected or not. It is unknown what the plan forward will be.

Event Description

It was initially reported that the patient had high impedance on a recent systems diagnostics. It is unknown want interventions will be taken but surgery is likely but has not occurred to date. There was not known trauma or manipulation that would have contributed to the patient's high impedance. X-rays were taken and provided to the manufacturer. X-rays did not show any discontinuities in the lead. There was a suspect issue that one of the electrodes may not be on the nerve as the electrodes did not appear to be aligned with each other. This has not been confirmed and may be due to the patient's anatomy. It was also unable to be confirmed that the pin was fully inserted based on the available images and the image quality of the x-rays. Good faith attempts for more information have been unsuccessful to date.
