The device has not been returned to omsc but was returned to (b)(4) for evaluation.From the inspection result of the device by (b)(4), omsc confirmed the following: omsc determined that the bending tube had a pinhole which was evidence of laser miss-irradiation within the instrument channel by the user.The bending section rubber had broken near the pinhole of the bending tube.The exact cause of the reported event could not be conclusively determined, because the device has not been returned to omsc.However, based upon the past similar cases, omsc concluded that the reported event may have been caused by the user misfiring a laser in the instrument channel, which melted a portion of the bending tube and bending section rubber.The instruction manual provides preventive measures against the reported failure mode.Device history record (dhr) review indicates that the product was manufactured and tested in accordance with all applicable procedures and met all final product release criteria.If additional information becomes available, this report will be supplemented.
