    摘要： An expandable stent prosthesis is disclosed in which the apices of the bends located at at least one end of the stent are individually twisted at an angle to the circumference of the stent to form a fan blade-like arrangement when viewed from that end. The fan blade-like arrangement allows the stent to expand from the compressed condition during deployment such that likelihood of a strut or bend of the stent become entangled with a barb or adjacent strut or bend, is reduced. In one embodiment of the invention, the fan blade-like arrangement results from plastically deforming the individual apices, while in another embodiment, the apices are twisted into the fan blade-like arrangement during the loading process, such as by use of a suture thread to pull the apices into alignment.

    摘要： An improved prosthesis assembly for placement at an aneurysm in the bifurcated lumen of the aorta and the common iliac arteries extending therefrom. The prosthesis assembly includes a single lumen graft or a bifurcated lumen graft having a main body and ipsilateral and contralateral limbs extending therefrom. The main body and ipsilateral and contralateral limbs each have a spring assembly about their orifices for conforming that portion of the graft to the wall of the vessel lumen. The main body spring assembly has an improved barb with first and second attachment arms for securely anchoring the spring assembly to the vessel wall. The improved barb includes two forms of mechanical attachment such as, for example, a helical coil body positioned around a spring assembly arm and, secondly, a bonding material such as, for example, solder for fixedly attaching the coil and spring assembly arm. The attachment arms of the barb are positioned longitudinally along the spring assembly arm for engagement with the vessel wall without engaging each other when the spring assembly is in a collapsed condition. The ipsilateral and contralateral spring assemblies also include the improved barb with only a single attachment arm for anchoring the spring assembly to the vessel wall.

    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.

    摘要： A medical grasping device (1) has an elongate control member (9) with a grasping member (17) proximal to its distal tip. An outer sheath (3) with a passageway therethrough surrounds the elongate control member and is relatively movable with respect to the control member. A control assembly (2) disposed at a proximal end of said outer sheath has a fixed handle (5) and a sliding handle (7) and the proximal end of the elongate control member is fixed to the sliding handle to move the control member. The grasping member (17) has a plurality of pre-formed wire loops (50, 52, 54, 56) which self-deploy transversely upon emerging from said distal end of said outer sheath. Each wire loop is fastened to substantially opposite sides of the elongate control member so that each of said wire loops is substantially semi-circular upon full deployment and the respective ends (27, 29) of each wire loop extend substantially in opposite directions from the elongate control member.
