    • A delivery system (10) for implanting a medical device (30) such as a venous valve into the vasculature of a patient. The delivery system includes a delivery catheter (11) having a device-containing portion (15) adjacent to the distal end (14) thereof, and an inner member (16) extending through the catheter and beyond the distal end thereof, to an atraumatic distal tip portion (17) forward of the catheter distal end. The inner member extends through the medical device in the device-containing region, includes a proximal portion (18) with sufficiently large diameter to prevent longitudinal movement of the device as the catheter is retracted during deployment, and centers the device upon release from the distal catheter end during deployment. The inner member is preferably radiolucent underlying the device for contrast with radiopaque markers (43) of the device. The inner member preferably includes a flat portion (35) extending from the device-containing portion to the proximal end (22) to form a passageway or lumen (21) with the delivery catheter to transmit hydrating fluid to a device such as a valve containing lyophilized tissue requiring hydration immediately prior to patient implantation.

    • 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.
    • 本发明提供了通过恢复对血管的通畅来治疗血管病变的装置和方法,同时降低栓塞进入血流的可能性。 在第一实施例中,该装置包括具有近端区域和远端区域的移植物,附接到移植物的远侧区域的第一支撑构件和附接到移植物的近端区域的第二支撑构件。 第一和第二支撑构件可以分别包括第一和第二支架。 第一个支架部署在血管状态的远端,第二个支架部署在血管状态附近,使得移植物跨越血管状态的长度,以在治疗血管疾病期间截留栓塞。 在替代实施例中,第一支架适于在位于远离血管状态的位置处的血管内展开,并且移植物适于被转动以形成适于在治疗血管状况期间阻塞栓塞移出的口袋。 然后第二支架随后可以部署在血管状态附近,使得捕获在移植物袋内的栓塞被有效地从血流中密封。
