The recipient had a head trauma in the first half of 2021, in situ measurements from (b)(6) 2021 showed abnormal results and the user show poor auditory responses.No redness or swelling over the skin was reported.The recipient was re-implanted with a new device.
Additional Manufacturer Narrative
Conclusion: damage to the active electrode which is consistent with minute device mobility was determined to have led to device failure over time due to fatigue breakages.Also, an impact to the head might have weakened the fixation of the active electrode and could also be a factor for electrode mobility.The investigation results appear to match the problems mentioned in the recipient report.This is a final report.
