摘要： 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. Upon balloon-expansion, the graft extension is frictionally engaged with the contralateral leg of the aortic graft. A third catheter assembly including a second extension graft is provided for introduction of the extension graft and balloon-expansion thereof for frictional engagement with the ipsilateral leg of the graft.

摘要： 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. Thereafter, the radial expandable endoluminal prosthesis mounted on the delivery catheter is deployed and implanted by an expansion device (e.g., balloon) formed on the delivery catheter. The delivery catheter may incorporate one or more outflow apertures at specific location(s) to facilitate injection of radiographic contrast medium in a manner which will check for leakage around the endoluminal prosthesis, after the endoluminal prosthesis has been radially expanded and implanted.

摘要： An intraluminal catheter for directing a guidewire and/or catheter in a desired direction within a bodily vessel or cavity. The intraluminal catheter has a first elongate tubular member and a support means which can comprise a second elongate tubular member that can pass over a main support guidewire. The catheter acts as a platform as the guidewire is passed through the first elongate tubular member and is deflected transversely outwardly by an angled surface through an aperture. A second intraluminal catheter has a first elongate tubular member and a support means comprising a second elongate tubular member. The first elongate tubular member has a main portion and an end portion, with the end portion being deflectable relative to the locus of the main portion so as to direct the guidewire passing through the end portion in a desired direction in the bodily vessel.
