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.
A self-expanding prosthesis for repairing an aneurysm, comprising: a bifurcated endovascular graft having a main body and first and second limbs extending therefrom, said main body including a main bore extending longitudinally therein and having a cranial orifice, said first limb including a first
A self-expanding prosthesis for repairing an aneurysm, comprising: a bifurcated endovascular graft having a main body and first and second limbs extending therefrom, said main body including a main bore extending longitudinally therein and having a cranial orifice, said first limb including a first bore extending longitudinally therein, communicating with said main bore, and having a first caudal orifice, said second limb including a second bore extending longitudinally therein, communicating with said main bore, and having a second caudal orifice; a first radio-opaque, imageable marker extending longitudinally along said first limb; a second radio-opaque, imageable marker extending longitudinally along said first limb and spaced at least a predetermined distance away from said first marker; a self-expanding stent positioned in said main bore about said cranial orifice; a tubular introducer sheath having a single wall and a sheath bore of a constant diameter extending longitudinally therethrough; and a central carrier coaxially positionable within said sheath bore of said sheath, said central carrier including a vascular dilator head region having a fixed shape, a portion mating with and approximating said constant diameter of said sheath bore, a shaft region approximating said constant diameter of said sheath bore, and a stem region positioned between said head and shaft regions and being smaller than said constant diameter of said sheath bore for positioning coaxially said self-expanding cranial stent, said main body and at least one of said first and said second limbs of said graft therearound and in said sheath bore.
