Manufacturer Narrative

*h4: the device was manufactured in may 2019.This report is being supplemented to provide additional information based on the legal manufacturer's final investigation.During testing, the returned tube had compressively buckled and was torn.The grasping portion was unable to retract into the tube when the ring was pulled.The grasping section was unable to close even though this portion was not torn.However, when the ring was operated by holding the broken area after the tube was straightened, the grasping portion was able to open and close.A review of the device history record (dhr) found no deviations that could have caused or contributed to the problem described above.The dhr confirmed that the subject device was shipped in accordance with the specifications.A definitive root cause for this issue was not established.However, it is probable that the issue occurred because a compressive force beyond the standard value was applied to open and close the basket.The repetitive excessive force was thought to have caused the proximal end of the tube to buckle and eventually tear/break.The occurrence of the reported problem can be prevented by adhering to the instructions for use (ifu) which states the following: ¿·do not coil the insertion portion with a diameter of less than 15 cm.This could damage the insertion portion.·never use excessive force to open or close the grasping portion.This could damage the instrument.·when the grasping portion does not open and/or close smoothly, do not apply force but set the scope¿s angle back, or move the position of the grasping portion until the basket opens and closes smoothly.If the action is forced, the tube may stretch and the resistance of the handle may increase.Also the calculus may not be retrieved, and/or the grasping portion with calculus engaged may not be removed from the body.¿ olympus will continue to monitor field performance for this device.
