    摘要： A generally tubular intraluminal vascular graft having a linear shape that may be radially expanded from a compressed state to an expanded state within a body vessel is disclosed. The graft includes a plurality of stent portions which take the form of undulating filaments extending circumferentially along the tubular body and forming a generally ring-shaped configuration. The graft may further be equipped with a plurality of specifically-configured engagement members disposed on the outer surface of the graft which are configured to frictionally engage an inner wall of a vessel so as to inhibit longitudinal movement of the tubular body without piercing the vessel wall.

    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： A delivery system and method for delivering a prosthetic heart valve to the aortic valve annulus. The system includes a balloon catheter having a steering mechanism thereon for delivering a balloon-expandable prosthetic heart valve through an introducer in an antegrade fashion to the aortic annulus. The balloon catheter passes through an introducer that accesses the left ventricle through its apex and a small incision in the chest wall. The balloon catheter includes a deflecting segment just proximal to the distal balloon to facilitate positioning of the prosthetic heart valve in the proper orientation within the aortic annulus. A slider in a deflection handle may be coupled to a deflection wire that actuates the deflecting segment. The method includes using two concentric rings of purse-string sutures around the puncture in the left ventricular apex to maintain a good seal around instruments passed therethrough. The prosthetic heart valve may be installed over the existing calcified leaflets, and a pre-dilation valvuloplasty procedure may also be utilized.

    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： An cardioplegic fluid delivery catheter includes an expandable member for occluding the ascending aorta of a patient. A length of the catheter allows the distal end to be within the ascending aorta while the proximal end extends from a peripheral artery. The delivery catheter has a multi-lumen construction with a primary lumen extending configured to allow a cardioplegic fluid to be delivered to the aorta. Secondary lumens provide for balloon inflation and aortic root pressure monitoring. The delivery catheter includes a shaft having a pre-determined curve profile at a distal end of the delivery catheter. The pre-determined curve profile generally corresponds to the curve of the bottom surface of the aortic arch. The shaft may be eccentric to the expandable member such that retraction of the shaft causes a distal tip to be parallel within the ascending aorta.
