Manufacturer Narrative

The subject device was not returned to olympus for evaluation due to the single use device being discarded by the customer.A review of the device history record (dhr) found no deviations that could have caused or contributed to the reported malfunction.The dhr confirmed that the subject device was shipped in accordance with the specifications.A definitive root cause could not be determined.The exact cause of the "needle wouldn't go deep enough" could not be conclusively identified, because the device was not returned for evaluation and there were no abnormalities on the device in the device history record.Although the root cause cannot be conclusively identified, based on the investigation result in the past, a likely mechanism causing the reported phenomenon might be the following: probable cause of the failure: the stylet was withdrawn from the needle section before the needle section was inserted into the sheath section.The needle section was inserted into the sheath section with the stylet was being withdrawn from the needle section.The tube of the needle section bent due to a force when the needle section was inserted into the sheath section.The tube was bent.Therefore, a fluid could not inject.The instruction manual contains the following descriptions, and it warns against this event.(rk1157 rev.04).Before use, prepare and inspect the instrument as instructed below.Should any irregularity be observed, do not use the instrument.Use a spare instead.Do not withdraw the stylet before locking the sheath section and the needle section together by positioning the slider at the 1st click stop position.Otherwise the tube could buckle when the needle section is inserted into the sheath section.Operate the slider slowly.Otherwise, the tube could buckle.Be sure to use a fluid intended for patient use when inspecting injection.If other fluids are used, the fluids may remain in the instrument.This could pose an infection control risk or cause tissue irritation.Insert the instrument slowly.Abrupt insertion could damage the endoscope and/or instrument.Do not push in the slider abruptly.The needle may extend abruptly.This could cause patient injury, such as perforations, hemorrhages or mucous membrane damage.Olympus will continue to monitor field performance for this device.
