Bifurcated vascular graft and method and apparatus for deploying same
First Claim
1. A bifurcated vascular graft comprising:
- a hollow tubular body member having first and second open ends, said second open end defining a first opening, said hollow tubular body member comprising a first stent;
a first hollow tubular limb member having first and second open ends; and
a second hollow tubular limb member having first and second open ends wherein the first open end of each of said first and second hollow tubular limb members extends through said first opening and is connected to the hollow tubular body member at a circumference of the first open end of said hollow tubular body member such that a length of said limb members extends from the first open end to the second open end of said hollow tubular body member and is circumferentially contained within said hollow tubular body member;
wherein the first open ends of said first and second hollow tubular limb members have first circumferential portions that are attached to each other along a diameter of the first open end of the hollow tubular body member which divides the hollow tubular body member into first and second lumens, and second circumferential portions which are not attached to one another are connected to the circumference of the first open end of the hollow tubular body member;
wherein said first and second hollow tubular limb members extend beyond the second end of the hollow tubular body member; and
wherein said first hollow tubular limb member includes a second stent and the second tubular member includes a third stent, the second and third stents only encompassing portions of the first and second hollow tubular limb members that extend beyond the second end of the hollow tubular body member.

Abstract
A structurally supported bifurcated vascular graft is described having a hollow cylindrical body graft with a top end and bottom end and two hollow cylindrical limb grafts which are attached to the hollow cylindrical body graft near the top end of the body graft. One or more structural supports or stents are attached to either the interior or exterior of the body graft and limb grafts. Further, an apparatus and method for delivering a one-piece bifurcated vascular graft is also described which includes first and second hollow limb tubes for containing the limbs of a bifurcated graft, a third hollow body tube for containing the body of a graft, and a hollow delivery tube capable of encompassing the limb tubes and graft body tube.
