Event Description

It was reported that during interrogation an error code 6 was observed for the patient.Error code 6 involves unexpected device reboots resulting in disablement of therapy.Troubleshooting for the error code has not been attempted, and the patients generator remains disabled.Internal data from the generator was received and reviewed.The device history records of the generator was reviewed.The generator passed final functional tests prior to distribution.The generator was manufactured before the screening process was implemented to mitigate the potential for gc5 reboots.Internal investigation has identified that the root cause of the unexpected device reboot is related to a hardware bug within the microcontrollers used in these devices and interaction with the device firmware.No other relevant information has been received to date.
