Manufacturer Narrative

This report is being supplemented to provide additional information based on the legal manufacturer's final investigation.The device lot number was not received however, the device history records (dhrs) for the past year prior to the aware date of this event were inspected and no abnormalities were found that could have lead to the reported event.The age of the device is unknown since the lot number was not received.Based on the results of the investigation, the exact cause could not be conclusively identified since the device was not retuned.It is likely that the phenomenon occurred due to the compressive bucking on the needle tube.The ifu warns the following: "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.": the event may have been prevented by following the instructions for use which states: ·straighten out the instrument before inspecting it.The instrument can be damaged if it is coiled while the handle is operated.·operate the slider slowly, otherwise the tube could buckle.·when inserting the instrument into the endoscope, retract the needle into the sheath, hold the instrument close to the biopsy valve, and keep it as straight as possible relative to the biopsy valve.Otherwise, the instrument could be damaged.·insert the instrument slowly.Abrupt insertion could damage the endoscope and/or instrument.·stop using the instrument if the insertion portion bends excessively during use.This could result in malfunction, such as failing to extend the needle or inject a fluid.E2 / e3: multiple attempts were made to obtain information.If additional information is received, a supplemental report will be filed.Olympus will continue to monitor field performance for this device.
