The branch portion is independently moveable relative to the main body.

Abstract: Methods and apparatus for placing a bifurcated aortic graft, with extensions, into a body lumen. An aortic graft is provided with a unique combination of self-expanding a balloon expandable wires. The aortic graft is bifurcated and includes ipsilateral and contralateral legs. Two extension grafts are provided for frictional engagement with the legs of the aortic graft. For placement of the bifurcated aortic graft with extensions, an introducer assembly including a dilator and a sheath assembly provides access for the introduction of a main catheter and a directional catheter. The main catheter is provided for deployment of the bifurcated aortic graft within the lumen of a vessel. A balloon is provided on the main catheter for expanding the balloon-expandable wires of the aortic graft. The directional catheter, which includes a deflecting spring portion, permits placement of a guidewire through the ipsilateral leg and into the contralateral leg of the aortic graft.

Abstract: Supplemental intraluminal graft extension achieved by cuff-means substantially fortify and enhance endovascularly emplaced systems, particularly for bridging aneurysms. Multiple embodiments based upon overlapping of at least two segments are taught. Cuff-means likewise have applications to restore patency to, or substantially enhance, prior failing emplacements of both home-made and other commercial devices.

Abstract: An intraluminal graft includes a tubular graft body extending along a cylindrical axis, a plurality of wires spaced apart from each other and arranged to circumferentially reinforce said tubular graft body along a substantial portion of its length, and a body surface including an inner surface region and an outer surface region. The body surface defines a plurality of apertures extending from an exterior space, and a first portion of a first wire is in the interior space while a second portion of the first wire is in the exterior space.

Abstract: A system for delivering and implanting a radially expandable endoluminal prosthesis within a body lumen (e.g., blood vessel). The system comprises a) an introducer/dilator assembly, and b) a delivery catheter/loader assembly. The introducer/dilator assembly comprises an elongate tubular introducer sheath which may be provided with a valving assembly mounted on the proximal end thereof. Such valving assembly may incorporate i) a hemostatic valve, ii) a first sealing valve and iii) a second sealing valve, positioned in series, to prevent leakage of body fluid out of the proximal end of the introducer and to permit two or more elongate members (e.g., catheters, guidewires) having differing outer diameters to be inserted through the introducer without leakage of body fluid therefrom. A dilator, which has regionalized differences in stiffness, is initially deployable within the lumen of the introducer to facilitate advancement of the introducer to its desired location within the body.
