It was reported that during pre-surgery it was observed that the drive shaft of the perforator driver device was bent.During in-house engineering evaluation it was observed that the driver device was locked up and would not rotate.There were no delays to the surgical procedure as an identical spare device was available for use.There was no patient involvement reported.There were reports of injuries, medical intervention or prolonged hospitalization.All available information has been disclosed.If additional information should become available, a supplemental medwatch report will be submitted accordingly.

The actual device was returned for evaluation.Reliability engineering evaluated the device and the reported condition was confirmed.An assessment was performed which found that the device had a bent driveshaft and was locked up and would not turn.It was determined that this was due to mishandling (user error) by dropping or hitting the device against something and from not using the protective cap.The assignable root cause was determined to be due to misuse, abuse, and/or user error.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.
