Manufacturer Narrative

(date of event): the exact date of the event is unknown.The provided event date (b)(6) 2020 was chosen as a best estimate based on the date of receipt.(b)(4).The returned autotome rx 44 was analyzed, and a visual evaluation noted that the cutting wire was broken.Additionally, the working length was twisted at the distal section and kinked at 53cm from the proximal section and 110cm from the distal tip.The device was observed under magnification and the cutting wire was blackened, and the cut of the cutting wire was not smooth.A functional evaluation was performed by loading a test guidewire through the guidewire port using short and deliberate movements and it advanced through the tome.Bowing and continuity tests were not performed due to the condition of the device.Leakage test was performed by injecting water through the injection hub port and it flowed as intended.No other problems with the device were noted.The product analysis revealed that the cutting wire was broken 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 generated if there was no constant contact with the tissue when electrocautery current was applied or if voltage exceeded the maximum voltage rating.Additionally, the working length was twisted and kinked.This condition could be generated upon manipulation of the device and multiple attempts to rotate the device.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.
