H6- medical device problem code 2017 - failure to follow steps / instructions.The device was not returned for analysis.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 incidents from this lot.Reportedly, a.018 guide wire was used.It should be noted the absolute pro ll peripheral self-expanding stent system instructions for use (ifu) states: one 0.035¿ (0.89 mm) diameter guide wire.The investigation determined the reported difficulties appear to be related to deviation of the instructions for use and subsequent circumstances of the procedure as it is likely that use of the undersized.018¿ guide wire resulted in the distal shaft to be bent in the anatomy resulting in preventing the shaft lumens from moving freely; thus resulting in the reported mechanical jam and the reported activation/deployment failure.Manipulation of the compromised device in attempts to deploy the stent by pushing the thumbwheel resulted in the reported noise/snap sound heard as the thumbwheel gears were binding.As reported, the stent only partially deployed and was removed from the anatomy, noting some stent fragments remain in the patient.There is no indication of a product quality issue with respect to manufacture, design or labeling.
