Manufacturer Narrative

The suspect medical device was not returned to the mfr for eval/investigation but to olympus medical systems corporation (omsc), (b)(4).The eval/investigation found the hf resection electrode with heavily deformed and twisted fork tubes.Furthermore, the loop wire is damaged/broken and also deformed.Causal for this damage and the subsequent breakage of the loop wire is mechanical overload by the application of excessive force.Therefore this incident was attributed to abnormal use/off-label use and the case will be closed from olympus side with no further actions.However, the incident will be recorded for trending and surveillance purposes and the user will be informed about the investigation results and pro re nata trained again on the correct usage of the olympus medical devices.Olympus submits this incident as a medical device report (mdr) in abundance of caution.
