A vascular graft for a primary vessel adapted to bridge a side branch. The graft is especially useful for providing a support tube for a primary graft in the primary vessel on one side of the side branch. The graft includes first and second tubular sections separated by a gap. A bridging member connects the first and second tubular sections across the gap and may include a relatively rigid strut to prohibit relative axial movement of the two sections. There may be one, two or more bridging members to define one, two or more apertures through which blood can flow from within the graft through to the vessel side branch. The graft may include a flexible, desirably fabric, body supported by a wireform stent that is either self- or balloon-expandable. The graft may be deployed within the abdominal aorta on both sides of the renal arteries and have two apertures for blood to flow from the aorta to the renals. The infra-renal section provides a uniform tubular anchoring surface for a trunk portion of a bifurcated graft used to repair an abdominal aneurysm extending to the iliac arteries.

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. In turn, a second introducer sheath and a second catheter assembly are provided contralaterally for introduction of a graft extension.

606192, 606194, 604 9601

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. Thereafter, the dilator may be removed from the introducer sheath and the delivery catheter/loader assembly may be attached to the introducer, such that the delivery catheter having the prosthesis mounted thereon may advanced through the introducer, to a desired location within the body.

A transfer device usable in a system for intraluminal treatment of a selected site in a body of a patient in which the transfer device comprises an integral pump for pressurizing and circulating fluid through a fluid path defined by the transfer device and associated catheter. A removable fluid cartridge is provided including a reservoir from which fluid is drawn by the pump and into which fluid is returned after being circulated through the fluid path. The pump may be a peristaltic pump and the fluid cartridge may include an elongated fluid pick-up having an inlet through which fluid is introduced into the transfer device. The fluid pick-up is sized in length so that the inlet is always submerged in the fluid regardless of the orientation of the transfer device.

A woven vascular graft having a texturized outer surface to promote tissue ingrowth into the graft. The outer surface of the graft is equipped with a plurality of threads that are woven into, and extend from, the outer surface. The threads may be arranged in rows, lines or a geometric pattern. Alternatively, the threads may be towel-like. Such towel-like threads may be arranged in the form of a cuff at each end of the graft, or may cover larger portions of the exterior of the graft. The graft may be equipped with only one texture, or with a plurality of different textures.
