Model Number 104
Device Problems Pin; High impedance; Malposition of device ; Lead
Event Date 10/01/2009
Event Type  Malfunction  
Event Description

Reporter indicated that the patient had recently undergone a generator replacement surgery. At the patient's first visit to the neurologist, it was noted that the device was registering high impedance. X-rays were taken and sent to the manufacturer for analysis, which found that there may have been an issue with proper insertion of one of the lead pins into the generator. The patient was taken into surgery to reseat the lead pin to see if the high impedance resolved. Once the lead pin was removed and reinserted properly, the high impedance resolved. Attempts for information as to whether diagnostics were performed at the original replacement surgery, were unsuccessful, thus the cause for the lead pin not being properly connected to the generator cannot be determined.
