The suspect medical device was not returned to olympus for investigation/evaluation.Therefore, the investigation/evaluation was performed exclusively on the basis of the information provided by the customer.The reported failure is a known fault pattern.Wear and tear due to frequent use in connection with repeated great bending and/or tensile loads most likely caused individual or all wires inside the cable to break.When the generator was activated, this led to the reported short circuit and voltage flashovers in the damaged area, which then caused the cable to burn through.According to the article¿s lot number, the hf-cable was manufactured in december 2019.It is therefore assumed that the hf-cable was used longer than the 12 months the cable is designed for.Thus, this event/incident can most likely be attributed to age-related wear and tear in connection with improper handling by the customer and thus 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-cable without showing any abnormalities.The case will be closed on olympus side with no further actions.However, the reported event/incident will be recorded for trending and surveillance purposes and the user will be informed about the investigation results.
