The subject device was returned to omsc for evaluation.Omsc reviewed the manufacturing history (dhr) of the subject device and confirmed no irregularity.Omsc checked the subject device and found that the ultrasonic propagation fluid medium leaked from the distal end and that the insertion tube was torn.Based on the result of the omsc evaluation, omsc concluded that the reported phenomenon was caused by a tear of the insertion tube and the leakage of the ultrasonic propagation fluid medium leaking through the tear.The exact cause of the tear of the insertion tube could not be conclusively determined, but there was the possibility that it was attributed to the external force such as the hit against the instrument channel port of the endoscope, and so on.If additional information becomes available, this report will be supplemented.
