The device was not returned to olympus for evaluation.The root cause of the reported event cannot be determined at this time.The instruction manual warns users ¿do not insert the instrument into the endoscope if the stopper is not attached to the tube sheath between the tube joint and control section.Otherwise, the clip will extend from the tube sheath.It may also cause the insertion portion of the instrument to extend from the distal end of the endoscope abruptly.This could cause patient injury, such as perforation, bleeding, or mucous membrane damage.It could also damage the endoscope and/or instrument.¿.

Olympus was informed that during an unspecified procedure, the first clip didn't engage from the endoscope and was pulled off the patient¿s tissue.The physician inserted a second to stop the bleeding; however, by the time the clip advanced from the sheath it was bent.It was reported that the bleeding had slowed and the physician decided another clip was not needed.
