摘要：
A stent for placement in a blood vessel with a wall having an aneurysm including an endovascular graft having a first end, a second end, and a tubular body that is expandable and extends from the first end to the second end. The stent also includes a coagulation apparatus attached to the tubular body between the first and second ends. The coagulation apparatus has a frame and a coagulant attached to the frame. When the stent is deployed within the blood vessel, the tubular body extends across the aneurysm and expands at the first and second ends to seal against the wall of the blood vessel such that blood is channeled across the aneurysm through the tubular body such that a pocket of blood is defined external to the tubular body. The frame expands into the pocket to orient the coagulant therein and promote coagulation of blood within the pocket.
