Abstract: An implantable, varied-diameter graft is seamlessly flat-woven to provide a seamless, varied-diameter graft. The graft includes a flat-woven tubular portion having opposed first and second tubular ends with a contiguous bulbous woven section therebetween. The bulbous woven section has opposed first and second open ends with the first bulbous end being contiguous with the first tubular end. The second bulbous end is contiguous with the second tubular end. The first tubular end has a first number of warp yarns interlaced with a plurality of fill yarns in a woven pattern to define a first flat-woven tubular diameter. The second end has a second number of warp yarns interlaced with a plurality of fill yarns in a woven pattern to define a second flat-woven tubular diameter. The bulbous section has a third number of warp yarns interlaced with a plurality of fill yarns in a woven pattern to define a third flat-woven tubular diameter.

Abstract: A stent-graft is provided that includes a bifurcated stent adapted for placement at the bifurcation of a bifurcated body lumen. The stent-graft further includes a graft that lines or covers at least part of the bifurcated stent. The graft defines a fluid passageway from the unbifurcated portion into one of the bifurcated stent branches. A closure prevents fluid from flowing through the second of the branches and into the other branch of the body lumen.

Abstract: A stent-graft is provided for defining a prosthetic fluid passage within a body lumen. The stent-graft includes a graft having a forward section, and a pilot stent located within the forward section of the graft. The pilot stent has an expanded diameter less than that of a lumen in which it is to be deployed to permit fluid flow within the lumen during deployment of the stent-graft. Means are provided for subsequently expanding the pilot stent and the graft to the full diameter of the lumen.
