(b)(4).The returned profile was analyzed, and a visual evaluation noted that the wire was kinked and the working length was ripped, torn and kinked making it impossible to extend and retract the loop.A continuity test was performed, and the device passed since the device's electrical resistance was within specification.No other issues with the device were noted.The reported events of loop failure to cut and wire kinked were confirmed.The investigation also found the working length to be ripped, torn and kinked.The product record review confirmed that this is not a new failure type and the risk is anticipated.There is no evidence of a manufacturing issue, design or user issue which could have caused the complaint.Upon product analysis it was observed that the wire was kinked and the working length was ripped, torn and kinked.These types of failures could get damage during its manipulation.Most likely procedural factors as handling the device, the technique used by the physician during initial use, set-up, power-up, or shortly thereafter could have affected its performance and its intended purpose, leading to the reported event.Based on the information available and the analysis of the returned device, the code selected as the most probable complaint cause is adverse event related to the procedure.A review of the manufacturing documentation for this device revealed that no anomalies or deviations related to the event occurred during manufacturing.
