(b)(4).The device was not returned for evaluation.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 of the reported lot revealed no other similar complaints reported from this lot.It should be noted that the absolute pro self-expanding stent system utilizes a 0.035¿ (0.89 mm) guide wire as indicated on the product label and in the instruction for use (ifu).Additionally, the absolute pro instruction for use states: use of an undersized guide wire, with insufficient support, may cause kinking in the stent delivery system.Based on the reported information, it is likely that inadequate support for the shaft due to use of an undersized guidewire caused restriction to the distal shaft lumens in the anatomy (possibly over the aortic bifurcation), preventing movement of the shaft lumens and causing the thumbwheel to lock up resulting in deployment difficulty.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
