The user's hearing performance with the device is affected.The user was re-implanted (b)(6) 2025.
Additional Manufacturer Narrative
Additional information: based on the received information, a damage to the active electrode due to device minute mobility appears very likely.Reportedly a trauma occurred which was the onset of the reported issue.The impact might have weakened the fixation of the implant.Re-implantation was carried out, but the device has not been received for investigation yet.
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.Other damage found during device investigation are most likely related to the explantation surgery.This is a final report.
Event or Problem Description
The user's hearing performance with the device is affected.The user was re-implanted on (b)(6) 2025.
