    摘要： A device for deploying a mechanical closure device for closing a passageway in a body, for example a patent foramen ovale (PFO) in a heart. The deployment device has a first tubular structure having proximal and distal ends. A second tubular structure is substantially coaxial to and slideably engaged within the first tubular structure. The second tubular structure has a first substantially linear shape when constrained within the first tubular structure, and a second curvilinear shape when telescopically extended from the distal end of the first tubular structure. A third tubular structure is substantially coaxial to and slideably engaged within the second tubular structure. The third tubular structure is configured to provide sufficient rigidity to push the mechanical closure device from the distal end of the second tubular structure, and provide sufficient flexibility to assume a curvilinear shape when deflected by the second tubular structure.

    摘要： An endoprosthetic device for treating abdominal aortic aneurysms using suprarenal fixation. A stent ring is anchored in an area above the renal arties using self-flaring barbs that project during the nitinol expansion process. Sutures extend from the stent ring to an area below the renal arties to a bifurcated trunk portion comprising a nitinol fabric on a non-kinking frame. The bifurcated trunk is sealed proximal the iliac arteries and includes iliac leg holders having self-flaring retention struts for non-traumatic holding of iliac leg prosthetics. Suprarenal fixation and collapsible cells having retention projections and barbs that only flare during the nitinol expansion process assist in lowering the devices profile and sheathability for percutaneous delivery and may provide for recapturing the anchored device.
