Additional Manufacturer Narrative
This report is being supplemented to provide additional information based on the device evaluation and the legal manufacturer's final investigation.New information added to the following fields: d9, h3, h4, h6, h10.Correction to e1 (the complete facility name should be (b)(6) hospital") a review of the device history record found no deviations that could have caused or contributed to the reported issue.The device was returned, and an evaluation was completed for it.During inspection, olympus confirmed the reported event: "the knife ware was damaged".Based on the investigation results, a definitive root cause could not be determined.However, it is likely that the cutting wire, where the wire coating was torn, came into contact with the distal end of the endoscope when the forceps elevator was raised.This activated an electrical conduction, causing the cutting wire to heat up instantly at the contact point, which resulted in the cutting wire breaking.One attempt was made to obtain additional information regarding the reported event, but no response was received from the customer.The event can be prevented by following the instructions for use which state: " since the cutting wire is very thin, it may break off in the following cases: the distance between the papilla of vater and the cutting wire is very short, the output is too high or activated while the cutting wire touches metal parts of the endoscope, or the cutting wire is tightened too strong.When the cutting wire breaks off, its proximal end will be retracted toward the endoscope if the slider is pulled.If the slider is pushed, the cutting wire will be pushed out toward the papilla or move sideways.If the cutting wire breaks off, stop the output immediately and pull the slider completely to retract the broken cutting wire into the tube.Then withdraw the sphincterotome from the papilla.Otherwise, patient injury, such as perforations, bleeding, or lacerations within the biliary duct, and/or damage of the endoscope could result.When inserting the instrument into the endoscope, be sure that the cutting wire is parallel to the tube.Otherwise, the metal part of the forceps elevator may contact the cutting wire and peel off the coating material.Do not activate output while tissue is in contact with the torn or damaged coated portion of the distal end.If output is activated while tissue is contacting the torn or damaged coated portion due to insertion into or withdrawal from an endoscope, leakage current, decreased output, and/or thermal injury could result.If you feel the cutting is blunt, withdraw the device from the scope to examine if there is any peel off and tear at the coating portion." olympus will continue to monitor field performance for this device.
