Additional Manufacturer Narrative
The device was not returned to olympus for evaluation as it was discarded.As the device was not returned to the manufacturer the investigation was carried out based on the available information.Three attempts were performed to obtain additional information, but no response was received from the customer.Based on the results of the investigation, a definitive root cause cannot be identified.It can be inferred that friction resistance has increased between the outer tube and the needle tube due to buckling of the tube causing the reported event.A bending force might have been applied to the tube when the device was inserted into the endoscope, removed from the sterile package or during pre-inspection.This might have caused the tube to buckle.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.This issue is addressed in the instructions for use (ifu): the instruction manual contains the following descriptions, and it warns against this event.(gk6631 rev.11) "before use, prepare and inspect the instrument as instructed below.Should the any irregularity be observed, do not use the instrument; use a spare instead.Damage or irregularity may compromise patient or user safety, for example: posing an infection-control risk, causing tissue irritation, perforation, bleeding or mucous membrane damage, and may result in more severe equipment damage.Straighten out the instrument before inspecting it.The instrument can be damaged if it is coiled while the handle is operated.Do not coil the insertion portion with a diameter of less than 15 cm.This could damage the insertion portion.Before use, confirm that the needle and the insertion portion are not damaged.If any abnormalities such as significant deformations or excessive bends are found, do not use the instrument.Otherwise, it may cause perforation, bleeding, mucous membrane damage.Confirm that the needle extends in the endoscopic image are normal.If any abnormalities are found, do not use the instrument.Otherwise, it may cause perforation, bleeding or mucous membrane damage.When inserting the instrument into the endoscope, retract the needle into the tube, 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.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.Do not push the slider abruptly, otherwise the needle will be rapidly extended from the distal end of the tube.This could result in patient injury, such as perforation, bleeding or mucous membrane damage.It could also damage the instrument." olympus will continue to monitor the field performance of this device.
