The following information was reported to gore: on (b)(6) 2018 a patient was undergoing treatment of a superficial femoral artery occlusion with a gore® viabahn® endoprosthesis with propaten bioactive surface.The lesion was pre-dilated with a pta balloon.The gore® viabahn® endoprosthesis with propaten bioactive surface was advanced over a wire through a short 6fr sheath and positioned for deployment.Device deployment was initiated.Approximately one third of the deployment line was pulled when the deployment line became stuck, and deployment would not continue.The endoprosthesis was expanded halfway at this point.Deployment was attempted again, but was not successful.The procedure was converted to cut down with open repair under general anesthesia to remove the partially expanded endoprosthesis from the vessel.The patient did well following the open repair.

The engineering evaluation stated the following: an introducer sheath was returned but was not evaluated as it is not a gore product.Approximately 56 cm of deployment line connected the hub to the deployment knob.The endoprosthesis appeared compressed towards the tip end of the device.There was 7 cm of exposed distal shaft, upon which the endoprosthesis is mounted, at the transition.The endoprosthesis was partially expanded a total of 4 cm at the tip end.There was also partial expansion at 5.5, 6, and 19 cm from the tip end of the endoprosthesis.The deployment line nearest to the 4 cm of partial expansion appeared normal at 9 cm from the tip end of the device there is a single fiber from the deployment line that was looped around the constrained endoprosthesis.At 11 cm from the transition end, there were broken fibers.Based on the device examination performed, no manufacturing anomalies were identified.
