Patent ID: 8021413

Claim:
An intraluminal medical device comprising: a bifurcated main graft having a compressed configuration and an expanded configuration and comprising a proximal end, a distal end, and a body portion; the main graft body portion having an axial length from the proximal end to the bifurcation of the main graft; the distal end comprising a first branch and a second branch; a first extension graft and a second extension graft, each of the extension grafts having a compressed configuration and an expanded configuration and comprising at least one stent and having a body reinforcing portion having an axial length and a branch reinforcing portion; where, in the expanded configuration, each of the body reinforcing portions have a larger expanded dimension than the expanded dimension of the respective branch reinforcing portion; where, in the expanded configuration, the body reinforcing portions, together, have an expanded dimension that is generally equal to the expanded dimension of the main graft body; where, in the expanded configuration, the body reinforcing portions contact one another and sealingly engage one another within the main graft body to prevent fluid leakage; and where, in the expanded configuration, the axial length of the body reinforcing portion is substantially equal to the axial length of the main graft body portion.
