The following information was reported to gore: on (b)(6) 2018, a patient underwent treatment of a total stenotic occlusion of the right superficial femoral artery with a gore® viabahn® endoprosthesis with heparin bioactive surface proximally and a zilver ptx stent distally.On (b)(6) 2019, a device occlusion of gore® viabahn® endoprosthesis with heparin bioactive surface was reported to gore.The occlusion was observed from just below the sfa bifurcation to the popliteal artery.On (b)(6) 2019, the patient underwent thrombectomy using a fogarty catheter from just below a sfa bifurcation to the origin of the popliteal artery to treat the occlusion.Thrombus was confirmed in the previously implanted stents and progression was noted distal to the implanted stents.During the thrombectomy, the thrombectomy catheter became stuck on the stent, and the stent became bent.To correct the stent bending and to press the thrombus to the vessel wall, an additional viabahn was implanted inside the stent.The patient tolerated the procedure.
