Manufacturer Narrative

This is a supplemental report to provide additional information.The subject device was returned to olympus medical systems corp.(omsc) for evaluation.The operation wire of the subject device broke off near the handle.The coil sheath, the tube, and the operation wire broke off near the tip.The fracture surface was shaped as if it was severed by a mechanical tool.The severed loop and the hook were not returned to omsc.The manufacturing record was reviewed and found no irregularities.The exact cause of the reported event could not be conclusively determined since the reported event could not be confirmed from the device.Based on the past similar cases, omsc assumes that this event occurred since the loop was caught between the hook and the coil sheath after the loop was released in the tube sheath for an unspecified reason.The above device handling has warned in the instruction manual as follows.*do not try to forcibly withdraw the instrument from the endoscope when the loop cannot be detached from the instrument.Forcibly withdrawing the instrument could cause patient injury such as punctures, hemorrhages or mucous membrane damage.If the loop cannot be detached from the instrument, follow the procedures described in this section.If there are any deviations or crushed sections on the distal end of the coil sheath, it may not be possible to detach the loop from the instrument.*do not remove the loop from the hook while the coil sheath is not extended from the tube sheath.Otherwise, the loop may be tangled with the hook and become impossible to be removed.
