Visual inspection was performed on the returned device.The reported proximal shaft separation could not be confirmed; however, the distal end of the device was returned separated and therefore, it is likely a misinterpretation of the device location.The reported failure to advance and difficulty removing the device could not be replicated in a testing environment as it was based on operational circumstances.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other similar incidents and/or complaints from this lot.The investigation determined the reported difficulties appear to be related to operational context.There is no indication of a product quality issue with respect to design, manufacture or labeling of the device.
