Patent ID: 7122051

Claim:
A bifurcated graft for repairing vasculature capable of being assembled in-situ, comprising: a trunk portion having a graft component with a proximal end and a distal end, the graft component supported by a self-expanding stent structure comprising at least one longitudinal strut that provides longitudinal support substantially the length from the proximal end to the distal end and a plurality of said stent structure extending circumferentially less than 360° around the circumference of the distal end; at least one limb portion, each limb portion having a graft component with a proximal end and a distal end, the graft component supported by a self-expanding stent structure comprising at least one longitudinal strut that provides longitudinal support substantially the length from the proximal end to the distal end and a plurality of stent cells along the longitudinal strut that provides at least partial radial support at the proximal and distal ends; wherein the graft is assembled by inserting each limb portion proximal end into the trunk portion distal end such that the limb portion proximal end and trunk portion distal end overlap a variable distance between a minimum and maximum amount.
