CYBERONICS - HOUSTON LEAD MODEL 304 Back to Search Results
Model Number 304-20
Device Problem Detachment of Device or device Component
Event Date 10/11/2018
Event Type  Malfunction  
Event Description

The patient was reported to have pain in their neck. The physician believes that there was curling of the lead and that the electrode is off of the nerve. The physician believed that the pain was due to the electrode coming off of the nerve. The pain was described as intense pain when laying on their left side or leaning their head to the left, and that it would resolve when the patient¿s head was turned to the right. Per an xray report received, there was some change in the lead configuration, but it was not specified what was different. No discontinuities were seen. X-rays were reviewed. The x-rays did not capture the generator and no assessment can be made on the position, lead wires, or feed through wires. In the portions of the lead visible, no gross lead fractures or other anomalies were observed. Based on the images provided, there is no obvious confirmation of the electrode coming off of the nerve. The device was interrogated and diagnostics were within normal limits. No additional or relevant information has been received to date.
