The device was returned for analysis.The reported activation failure and the reported noise were unable to be replicated in a testing environment due to the condition of the returned device.The reported difficult to advance was unable to 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 did not indicate a lot specific quality issue.The investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that resistance was met with the very strong angulation and the highly tortuous anatomy resulting in the reported difficult to advance.Interaction and/or manipulation of the device resulted in the noted device damages (sheath chatter mark indentations and scratches, wrinkled sheath, kinked jacket stabilizer, outer member and inner member) resulting in preventing the shaft lumens from moving freely; thus resulting in the reported activation/deployment failure.Further manipulation in attempts to deploy the stent resulted in the reported noise/noted both proximal spool pegs smashed.The treatment appears to be related to the operational context of the procedure as reportedly the handle was disassembled in an attempt to fully deploy the stent and the device was removed from the anatomy and a non-abbott device was used to complete the procedure.There is no indication of a product quality issue with respect to manufacture, design or labeling.
