Event Description

Olympus was informed that during a therapeutic transurethral ureteral stenosis dilation procedure, the hf electrode did not come out sufficiently from the sheath when the working element was operated and thus no electricity was applied.Since no spare electrodes had been prepared the intended surgery had to be aborted.No further information was provided.

Manufacturer Narrative

The suspect medical device has not yet been returned to olympus for evaluation/investigation.Therefore, the exact cause of the patient's outcome and the reported phenomenon could not be determined and is being judged as unknown.However, if the suspect medical device is returned for evaluation/investigation or additional significant information becomes available, this report will be updated.

Manufacturer Narrative

Device evaluation: the suspect medical device was returned to the manufacturer for evaluation/investigation.The investigation found the wire at the proximal end of the electrode to be bent in two areas and the electrode contact including the wire to be missing.The distal end of the electrode was found to be intact.Due to the dimensional deviation/deformation, the electrode no longer fits into the sheath.This type of damage is caused by improper handling during instrument preparation.Most likely, the electrode was not carefully and securely inserted into the working element as described in the instructions for use but handled with excessive force.Thus, the event/incident can be attributed to user error.A material or quality problem can be excluded since a manufacturing and quality control review was performed for the affected lot number of the hf resection electrode without showing any abnormalities.The case will be closed on olympus side with no further actions.The reported event/incident will be recorded for trending and surveillance purposes and the user will be informed about the investigation results.
