Visual and functional analysis was performed on the returned device.The reported difficulty advancing the guide wire was confirmed.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 complaints.The investigation determined that the reported difficulties were likely related to procedural circumstances.It is likely that the difficulty encountered advancing the guide wire was the result of the severe kink/tear noted on the returned unit.Although a cause for the damage could not be determined, it may be possible that inadvertent mishandling during removal from the packaging or during preparation caused shaft to kink preventing the guide wire from advancing.Additional handling and the continued attempt to advance the guide wire with the shaft kinked may have caused the shaft to tear preventing any further advancement of the guide wire.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
