(b)(4).The returned jagtome rx 44 was analyzed, and a visual evaluation noted that the cutting wire was broken, kinked and blackened.The device was observed under magnification and the cut of the cutting wire was not smooth, indicating it was not a mechanical cut.No other problems with the device were noted.The product analysis revealed that the cutting wire was broken.Additionally, the cutting wire was kinked and blackened.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 there was contact between the device and the scope during energization or if the device exceeded the maximum rating of voltage during procedure.Also, kinking the cutting wire as a result or interaction with the scope and/or additional devices can contribute to a break in the cutting wire.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.
