This report is being supplemented to provide additional information based on the legal manufacturer's final investigation, to update d8, and make corrections to b5 and h6 coding.A review of the device history record found no deviations that could have caused or contributed to the reported issue.Based on the results of the investigation, the root cause could not be determined.It is likely the user applied excessive stress to the bending section which resulted in the damage to the bending tube.The event can be detected and 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 any irregularities such as dents, bulges, swelling, scratches, peeling of coating, holes, sagging, transformation, bends, adhesion of foreign bodies, missing parts, and protruding objects." "-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.
