Patent ID: 7691135

Claim:
A method of transluminally deploying a bifurcation graft at the bifurcation of a main vessel into a first and second branch vessels, comprising: providing a bifurcation graft having a main portion, a first branch portion, and a second branch portion, the bifurcation graft supported by a single delivery catheter with the main portion, the first branch and the second branch portion constrained in a radially compressed state by one or, the main portion having a diameter greater than a diameter of the first branch portion or the second branch portion; introducing distally the delivery catheter and the bifurcation graft through a first access site in the first or second branch vessel; transluminally advancing the bifurcation graft to the bifurcation; manipulating the delivery catheter to position the bifurcation graft such that the main portion is in the main vessel, the first branch portion is positioned at least partially in the first branch vessel, and the second branch portion is positioned at least partially in the second branch vessel; proximally retracting the bifurcation graft until the bifurcation of the graft is positioned in contact with the bifurcation between the first and second branch vessels, wherein the bifurcation of the graft is the juncture of the first branch portion and the second branch portion; expanding the main, first branch and second branch portions from their radially compressed states; and withdrawing the delivery catheter and each of the one or more restraints through the first access site; wherein the bifurcation prevents distal migration of the bifurcation graft.
