This report is being supplemented to provide additional information based on the legal manufacturer's (lm) final investigation.The b5 was corrected to include the reportable malfunction found by olympus personnel during the device evaluation.A review of the device history record found no deviations that could have caused or contributed to the reported issue.It has been more than 5 years since the subject device was manufactured.Based on the results of the investigation, it is likely that "whiteout in image" and "peeling off coating of the insertion section" were both due to physical stress applied to the insertion section during user handling.The stress likely caused the charged coupled device (ccd) unit to become damaged affecting the image.However, a definitive root cause for the events could not be established.The "whiteout in image" event can be detected by handling the device in accordance with the following section of the instructions for use: "inspection of the endoscopic image." the "peeling off coating on insertion section" event can be detected by handling the device in accordance with the following section of the instructions for use: "inspection of the endoscope." in addition, both the events "whiteout in image" and "peeling off coating of insertion section" can be prevented by handling the device in accordance with the ifu which states: do not strike, bend, hit, pull, twist, or drop the endoscope¿s distal end, insertion tube, bending section, control section, universal cord, or endoscope connector with excessive force.The endoscope may be damaged and could cause patient injury, such as burns, bleeding, and/or perforation.It could also cause parts of the endoscope to fall off inside the patient.Olympus will continue to monitor field performance for this device.
