Block e1 (initial reporter facility name): (b)(6).Block h6 (device codes): medical device problem code a0401 captures the reportable event of cutting wire broken.Block h10: the returned ultratome xl was analyzed, and a visual evaluation noted that the cutting wire was broken, blackened, and bent/kinked, consistent with the findings when the device was observed under magnification.The working length was free from obvious kinks and bends.No other problems with the device were noted.The reported event of cutting wire break was confirmed.Upon analysis, it was found that the cutting wire was broken, blackened, bent/kinked.The cutting wire being blackened indicates that the device was energized.Based on the condition of the device, the problem found could have been caused if the cutting wire was activated before use which may cause premature cutting wire fatigue and compromise the cutting wire's integrity.Not verifying that the cutting wire has exited the endoscope while electrical current is applied and not maintaining direct and constant contact with tissue when applying electrocautery current could also contribute to wire breakage.Also, excessive power may damage the integrity of cutting wire.The kinked cutting wire could have been generated if there was resistance felt at the cutting wire with the scope.Based on all gathered information, the most probable root cause of this complaint is adverse event related to procedure.A review of the manufacturing documentation for this device revealed that no anomalies or deviations related to the event occurred during manufacturing.A labeling review was performed and, from the information available, this device was used per the instructions for use (ifu) / product label.
