Event Description

This report pertains to one of two truetome 44 used in the same procedure.It was reported to boston scientific corporation that a truetome 44 was used in the bile duct during an endoscopic retrograde cholangiopancreatography (ercp) procedure performed on (b)(6) 2022.During the procedure, while endoscopic sphincterotomy (est) was performed to make papillary incision, the cutting wire of the truetome 44 "ruptured" when the device was energized.A second truetome 44 was used to make an incision; however, the cutting wire also "ruptured." the procedure was completed with another of the same device.There were no patient complications reported as a result of this event.No further information has been obtained despite good faith efforts.The reported event may suggest that the cutting wire broke.

Note: this report pertains to one of two truetome 44 used in the same procedure.It was reported to boston scientific corporation that a truetome 44 was used in the bile duct during an endoscopic retrograde cholangiopancreatography (ercp) procedure performed on april 25, 2022.During the procedure, while endoscopic sphincterotomy (est) was performed to make papillary incision, the cutting wire of the truetome 44 "ruptured" when the device was energized.A second truetome 44 was used to make an incision; however, the cutting wire also "ruptured." the procedure was completed with another of the same device.There were no patient complications reported as a result of this event.No further information has been obtained despite good faith efforts.The reported event may suggest that the cutting wire broke.

Manufacturer Narrative

Block h6: medical device problem code a0401 captures the reportable event of cutting wire broken.Block h10: the returned truetome 44 was analyzed, and a visual evaluation noted that the cutting wire was broken and kinked from the proximal pierced hole, which are consistent with the findings when the device was observed under magnification.Additionally, the ends of the broken cutting wire were blackened.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 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 contact between the device and the scope during energization or if the generator exceeded the maximum of voltage during the procedure.Also, energizing the device prior to performing sphincterotomy can compromise the cutting wire's integrity and cause a premature cutting wire fatigue.Once the cutting wire breaks, any attempt to remove the device from the scope can lead to the broken section hitting the working channel of the scope.This can kink/bend the cutting wire.It is most likely that procedural or anatomical factors encountered during the use of the device could have affected the device performance and its integrity.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.
