Manufacturer Narrative

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.It has been over 1 year since the subject device was manufactured.Based on the results of the investigation, it is likely that this phenomenon occurred due to the compressive bucking on the needle tube.It was likely that the friction between the outer tube and the needle increased by the following factors.·the needle extended/retracted while the tube was coiled in inspection of operation.·the slider was abruptly pushed.·angle of the distal end of the endoscope a definitive root cause cannot be identified.The instructions for use (ifu) instruction manual state: ¿- ifu warns against this event as follows: ·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 the field performance of this device.Correction to g3 of the initial medwatch.The aware date should be 23-nov-2021.
