Event Description

It was initially reported that the patient's generator was showing that it was near end of life. Later, the patient's mother stated the patient had experienced an increase in seizures, and now how voice changes with stimulation were not as intense, indicating the battery may be failing. The patient was sent for replacement surgery, where the near end of service indicator was seen; the battery was still supplying output current at this time. The patient's last known diagnostics showed the device to be properly functioning. Attempts for further information have been unsuccessful to date.

Event Description

Additional information was received on december 8, 2011 when the physician reported that the relationship of the increase in seizures to vns is unclear. No causal or contributory programming changes, medication changes, or other external factors preceded the onset of the increase in seizures. The patient's settings prior to battery replacement were listed as output=3. 25ma/frequency=30hz/pulse width=500usec/on time=30sec/off time=1. 8min/magnet output=3. 5ma/magnet on time=60sec/magnet pulse width=500usec/eri=yes on (b)(6) 2011. The physician also provided clinic notes dated (b)(6) 2011 that state the patient was doing well in terms of seizures and that his last seizures as about a year ago. After battery replacement, the patient was programmed back up to output=3. 25ma/frequency=30hz/pulse width=500usec/on time=30sec/off time=1. 8min/magnet output=3. 5ma/magnet on time=60sec/magnet pulse width=500usec during her follow up visit on (b)(6) 2011.
