Manufacturer Narrative

The subject device was received and evaluated.Device evaluation found the customers reported issue was able to be replicated.Visual inspection on the received condition performed and noted white foreign residue lodged inside the insertion portion tube.The white residue inside of the tube is in various sections throughout.The handle section appears normal, and the needle was fully retracted upon being received.The device was not received with the original packaging.A functional inspection noted it was able to fully extend and retract the needle out of the sheath without using excessive force.Furthermore, the injection inspection was tested by filling a syringe with water and attaching it to the injection port.The water was unable to be injected, and the movement from the syringe was restricted.More force applied to the syringe and the white foreign residue did not expel out the distal end.Attempted to extend the needle from the distal end side of the insertion portion and test the injection of fluid in both pushed and pulled directions.The syringe was again attached to the complaint device and fluid from the syringe did not pass through when in a pulled position.The pushed position still did not allow the fluid to pass through.Investigation is ongoing.This report will be supplemented accordingly following investigation.

Corrected information: the correct aware date for initial medwatch report (medwatch# 71548, mfr# 8010047-2021-16098) is 05-november-2021.This report is being supplemented to provide additional information based on the legal manufacturer's final investigation.A review of the device history record found no deviations that could have caused or contributed to the reported issue.The investigation did not establish a definitive root cause for the reported event.However, it was thought that the product problem may have occurred due to the compressive bucking on the needle tube.The buckling likely occurred when the needle was extended from the great friction between the outer tube and the needle.The reported event can be detected/prevented by following the instructions for use (ifu) which state: ¿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.¿ olympus will continue to monitor field performance for this device.Investigation activities have been opened to manage the actions related to this issue and any required mdr reporting.
