Additional Manufacturer Narrative
This report is being supplemented as a correction for information inadvertently left out of previous report: legal manufacturer's final investigation, device evaluation, d10, g2.The subject device was not returned to olympus for inspection, but a photo was provided.The customer's complaint was confirmed (the clip did not come off the applicator, the internal wire became loose and fell out of the metal catheter).The connecting rod was not broken from the clip.The devices from patient identifiers (b)(6) and (b)(6) were returned to olympus for inspection, and the customer's complaint was also confirmed (the clip did not come off the applicator, the internal wire became loose and fell out of the metal catheter).The connecting rods were not broken from the clip, but the control units were deformed.Olympus found the operating wires had come loose from the crimped parts.There were no signs of breakage at the tips of the operating wire.A review of the device history record (dhr) found no deviations that could have caused or contributed to the reported issue.The device was manufactured in november 2022, but the specific date is unknown.Based on the results of the investigation, it is likely the event (the clip did not come off the applicator) occurred because the operating wire came off from the caulking part due to the following mechanism: 1.I tried clipping when the shape and angle of the scope were strict.2.Due to the strict shape, the sliding resistance between the operation wire and the coil sheath increased.3.Due to the increased sliding resistance, the force was not transmitted to the tip side, and the slider could not be pulled until the connecting rod broke.4.The clip could not be released because the connecting rod did not break.Since the subject device could not be confirmed, and no abnormalities were detected in the dhr, the exact cause could not be determined.The event can be prevented by following the instructions for use which state: ·"do not pull out the rotary clip device until it hits the slider of this product and clipping is not completed.It may lead to perforation, major bleeding, mucous membrane damage, etc.·do not pull the slider of this product until it hits the end, and do not operate the angle of the endoscope before clipping is completed.It may lead to perforation, major bleeding, mucous membrane damage, etc.·if the clip does not come off from the rotating clip device, do not forcibly pull out the sheath.It may lead to perforation, major bleeding, mucous membrane damage, etc.·this product is intended to be used only when surgical operations are possible as an emergency measure.In the unlikely event that the clip does not come off the rotating clip device, see "chapter 4 emergency actions".·do not press the clip too much against the desired tissue.The intended performance may not be achieved, such as the clip being deformed and not closing completely." olympus will continue to monitor field performance for this device.
