Manufacturer Narrative

The subject device was returned to olympus medical systems corp.(omsc) for evaluation.The insertion portion was cut off at about 3 mm from the handle.The loop was caught outside the loop hanger which holds the loop.After removing the loop from the device, the movement of the loop cutter was examined.Foreign material was stuck on the loop cutter and the loop cutter could not be opened smoothly.There was no deformation found in the cutter and the loop hanger.The manufacturing record was reviewed and found no irregularities.Based on the past similar cases, it was known that the loop was caught in between the cutter and the loop hanger due to pulling the slider without positioning the loop vertically to the loop hanger.The above device handling has been warned in the instruction manual as follows; do not try to cut the loop that is not positioned on both edges of the loop hanger as plumb as possible for the blade.It may make cutting the loop impossible, or result in the loop getting caught in the distal end of the instrument, which could make it difficult or impossible to remove from the patient.In this case, use pliers to cut the insertion portion of the instrument where it extends from the biopsy valve of the endoscope.Remove the endoscope from the body, then reinsert the endoscope and cut the loop with a spare loop cutter.
