(b)(4).A visual evaluation of the returned device found that the working length of the needle and sheath were kinked near the distal end of the handle and the distal section of the needle was also found to bent.Functional test was performed and the needle was able to extend and retract however, resistance was felt when the handle was actuated due to the kinked found in the device.The reported event of needle would not extend was confirmed.Due to operational and anatomical factors encountered during the procedure including the needle bent in the distal section, this condition limited the overall performance of the device causing resistance due to the friction between the needle and sheath during the handle actuation.Therefore, the most probable root cause classification for the reported failure is operational context.A dhr (device history record) review was performed and no deviation was found.A search of the complaint database confirmed that no similar complaints exist for the specified batch.
