Manufacturer Narrative

Device was returned for evaluation. Evaluation of the device found a foreign object stuck inside the biopsy channel. An olympus boroscope was used to check the device biopsy channel and found that a broken piece of the foreign object was found lodged inside the biopsy channel approximately 40mm from the distal end side of the device. A brush or forcep was not able to pass through the biopsy channel due to the foreign object stuck inside. The foreign object was not able to be removed. In addition, leaking was observed in the channel. Based on evaluation findings, the reported issue was confirmed. The root cause of the issue was due to the wrong brush used to clean the scope, which became stuck in the device biopsy channel. The root cause of the issue was attributed to use error. In addition, as a preventive measure and as stated on the ifu : the channel cleaning brush is a consumable item. If the brush head is bent or kinked during use, the distal end of the brush may be damaged or come off. Confirm that the brush is free from any damage or irregularities before and after each use. Should a part of the brush come off, immediately retrieve it and carefully confirm that no parts are left inside the channel of the endoscope by passing a new cleaning brush or other endo-therapy accessory through it. Any parts left in the channel may drop into the patient during the procedure. Depending on the location, the missing part may not be recoverable by passing a new brush or other endo-therapy accessory through the channel. In this case, contact olympus.

 
Event Description
