摘要:
The present invention provides apparatus and methods for treating a vascular condition by restoring patency to a vessel while reducing the likelihood that emboli become dislodged into the bloodstream. In a first embodiment, the apparatus comprises a graft having proximal and distal regions, a first support member attached to the distal region of the graft, and a second support member attached to the proximal region of the graft. The first and second support members may comprise first and second stents, respectively. The first stent is deployed distal to a vascular condition, and the second stent is deployed proximal to a vascular condition, such that the graft spans the length of the vascular condition to entrap emboli during treatment of the vascular condition. In an alternative embodiment, the first stent is adapted to be deployed within a vessel at a location distal to the vascular condition, and the graft is adapted to be everted to form a pocket adapted to entrap emboli dislodged during treatment of the vascular condition. The second stent then may be subsequently deployed proximal to the vascular condition, such that emboli trapped within the graft pocket are effectively sealed off from the bloodstream.
