It was reported to boston scientific corporation that a spyscope ds ii access & delivery catheter was used during cholangioscopy procedure in the bile duct performed on (b0(6), 2020.According to the complainant, during the procedure, it was noticed that the distal tip of the spyscope ds ii detached.The procedure was completed with another of the same device.There were no patient complications reported as a result of this event.The patient's condition at the conclusion of the procedure was reported to be stable.*additional information received on (b)(6), 2020* reportedly, "foreign material appeared in the bile duct." this was confirmed to be part of the spyscope ds ii.Additionally, the detached part of the spyscope ds ii was not retrieved as the papillotomy was big enough that the part could just fall out through the papilla by bile flow.

Correction - block d4 (catalog number): corrected from 1759-02 to 4661.Block a2: patient's exact age is unknown; however it was reported that the patient was over the age of 18.Block h6 (device codes): problem code 2907 captures the reportable event of detached catheter component.Block h10: the returned spyscope ds ii was analyzed, and a visual evaluation was performed.No elevator marks were noted along the shaft.No additional damage was noted.Witness marks were observed on the contacts of the umbilicus connector, indicating it was connected to a controller.An image assessment was performed.The device was plugged into the controller.A live, clear image was displayed.Real-time x-ray was used to image the distal tip, including the camera and wires.The x-ray showed no camera wire damage at the camera on the distal tip.In the handle, no damage was observed to the printed circuit board assembly (pcba).The camera wire was noted as suspicious in the breakout region.The handle was opened and the components within were visually inspected.No issues were noted with the internal components.The reported event was not confirmed.Upon analysis, there were no issues identified with the returned device.Catheter tearing is a failure mode that is accounted for in the design, and is mitigated by material specification of the shaft, braid, and tip; therefore, it is unlikely that the event was due to material defect.Interaction with the duodenoscope elevator during the procedure can damage the catheter, as handling of these devices in tortuous anatomy may result in more forces applied to the shaft of the catheter.Based on all gathered information, the most probable root cause of this complaint is no problem detected.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 directions for use (dfu) / product label.
