The olympus representative reported on behalf of the customer that during the colonoscopy with lesion removal and after the ligation, the endoloop on the single use ligating device deployed correctly however, it remained attached to the spring.The emergency loop cutters were used to cut the string externally and the scope was removed over the endoloop catheter.The colonoscope was then reinserted and the loop cutter was used again to cut the endoloop from the spring/catheter, which was later completely removed.The user was able to use the emergency cutter to detach the loop and the procedure was completed.The loop stayed with the patient and eventually passed.The procedure lasted 79 minutes and was not prolonged.The anesthesia/sedation was extended approximately five to seven minutes to troubleshoot the device.The condition of the patient was not impacted by the failure.No further medical intervention was required as a result of the reported problem.
