The device was returned, and an initial evaluation was conducted by olympus; however, investigation is ongoing.During the initial evaluation, the user¿s report was confirmed.A leak was present from the distal end.The adhesive at the distal end was found peeling.The image had fiber breaking present.The angulation as well as the control knob were booth off due to a deformed bending section.If additional information becomes available following the device evaluation, a supplemental report will be filed.

This report is being supplemented to provide additional information based on the legal manufacturer's final investigation.A review of the device history record found no deviations that could have caused or contributed to the reported issue.It has been over 4 years since the subject device was manufactured.Based on the results of the investigation, it is likely that the user manipulated the subject device, applying excessive force to the bending section causing the reported event.However, the root cause could not be determined.The event can be detected/prevented by following the instructions for use (ifu) which state: ¿precautions: perform a leakage test on the endoscope after each precleaning procedure.Do not use the endoscope if a leak is detected.Use of an endoscope with a leak may cause a sudden loss of the endoscopic image, damage to the bending mechanism, or other malfunctions.Use of a leaking endoscope may also pose an infection control risk." "inspection of the endoscope: inspect the external surface of the entire insertion section, including the bending section and the distal end for dents, bulges, swelling, scratches, peeling of coating, holes, sagging, transformation, bends, adhesion of foreign bodies, missing parts, protruding objects, or other irregularities.¿ ¿do not operate the angulation control lever with excessive force in a narrow space to the opposite direction from the bending direction while the distal end of the endoscope is not moved.The bending section may be damaged.Check the tip position of the endoscope and the shape of the bending section using fluoroscopy, etc.Do not insert the insertion tube with excessive force and twist.¿ ¿do not insert the insertion tube with excessive force into the ureter or calix.The bending section may be damaged.¿ olympus will continue to monitor field performance for this device.
