摘要： A transluminal grafting system for grafting a prosthesis to the wall of a lumen includes a tubular graft provided with spring assemblies and anchoring barbs. The prosthesis is mounted on an apertured tubular carrier and a central control means is inserted into the bore of the apertured carrier. Mooring loops are attached to the prosthesis, pass through the apertures of the tubular carrier, and engage the central control means. An introducer sheath covers the system for smooth insertion into a lumen. When the graft has been positioned, the central control means maintains the axial position of the prosthesis. When the introducer sheath is pulled, the prosthesis is exposed and the spring assemblies return to an expanded state and anchor the graft against the internal wall of the lumen.

摘要： An improved prosthesis assembly for placement at an aneurysm in the bifurcated lumen of the aorta and the common iliac arteries extending therefrom. The prosthesis assembly includes a single lumen graft or a bifurcated lumen graft having a main body and ipsilateral and contralateral limbs extending therefrom. The main body and ipsilateral and contralateral limbs each have a spring assembly about their orifices for conforming that portion of the graft to the wall of the vessel lumen. The main body spring assembly has an improved barb with first and second attachment arms for securely anchoring the spring assembly to the vessel wall. The improved barb includes two forms of mechanical attachment such as, for example, a helical coil body positioned around a spring assembly arm and, secondly, a bonding material such as, for example, solder for fixedly attaching the coil and spring assembly arm. The attachment arms of the barb are positioned longitudinally along the spring assembly arm for engagement with the vessel wall without engaging each other when the spring assembly is in a collapsed condition. The ipsilateral and contralateral spring assemblies also include the improved barb with only a single attachment arm for anchoring the spring assembly to the vessel wall.

摘要： A stent graft for use in a medical procedure to treat a dissection of a patient's ascending thoracic aorta. The stent graft includes bare alignment stents at least at a proximal end, and often with a stent at both ends, each stent having opposing sets of curved apices, where the curved section of one broader set of apices has a radius of curvature that is greater than the curved section of the other narrower set of apices. The proximal stent is flared in a manner such that its broad apices occupy a larger circumference around the stent than do its narrower apices, where this flared feature provides for anchoring engagement near the aortic root in a manner not interfering with the coronary arteries or the aortic valve.

摘要： The present embodiments provide a valve for implantation in a patient, for example, an aortic valve. The valve comprises a proximal region comprising a cylindrical shape, and a distal region having a generally rectangular shape comprising opposing flat surfaces that are separated by narrower flat sides. A tapered region is disposed between the proximal and distal regions, where the tapered region comprises two opposing flat surfaces that transition into the opposing flat surfaces of the distal region. The opposing flat surfaces of the tapered region are angled relative to the proximal and distal regions. The opposing flat surfaces at the distal end of the valve allow fluid flow therethrough during antegrade flow and are generally adjacent to one another to inhibit blood flow through the valve during retrograde flow. Optionally, at least one reinforcement member may be coupled to the valve to prevent prolapse of the valve during retrograde flow.

摘要： A transluminal arrangement for positioning a prosthesis assembly at an aneurysm in the bifurcated lumen of the aorta and the common iliac arteries extending therefrom. The prosthesis assembly includes a bifurcated endovascular graft having a main body and ipsilateral and contralateral limbs extending therefrom. The assembly also includes main, ipsilateral, and contralateral spring assemblies each having a compressed state. When released from its compressed state, each spring expands a portion of the graft to substantially conform that portion of the graft to the wall of the bifurcated lumen. The transluminal arrangement comprises an elongated member extending through the main and ipsilateral bores of the graft and includes attachment sutures and an inner catheter extending therethrough for temporarily attaching the main and ipsilateral spring assemblies to the elongated member. An outer sheath contains the attached prosthesis assembly, whereas stent boots consisting of short length sheaths contain the ipsilateral and contralateral spring assemblies. A control limb delivery catheter and attachment sutures maintain the contralateral graft limb and spring assembly in the stent boot for placement in the contralateral iliac artery.
