On (b)(6) 2018, the patient was implanted with two gore® viabahn® endoprostheses with heparin bioactive surface (jhjr050502j/16466569 and jhjr052502j/18397400) to treat an occlusion of the right superficial femoral artery.On an unknown date in (b)(6) 2019, follow-up examination reportedly revealed occlusion in one gore® viabahn® device (it is unknown which device was occluded).There was reported collateral circulation approximately 7cm distal to the originally implanted stent graft.It was reported that the collateral circulation resulted in a competing blood flow, causing the occlusion.On (b)(6) 2019, the patient underwent endovascular treatment using an additional gore® viabahn® endoprosthesis with heparin bioactive surface and thrombectomy to treat the occlusion.The additional stent graft was placed to cover the collateral circulation.The patient tolerated the procedure.
