Expandable transluminal graft prosthesis for repair of aneurysm
DCFirst Claim
1. A self-expanding prosthesis delivery system comprising:
- a tubular introducer sheath having a sheath bore of a substantially 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 and a portion mating with and approximating said substantially constant diameter of said sheath bore, a shaft region approximating said substantially constant diameter of said sheath bore, and a stem region positioned between said head and shaft regions and being smaller than said substantially constant diameter of said sheath bore for positioning coaxially a self-expanding prosthesis therearound and in said sheath bore.

Abstract
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.
