Apparatus and methods for endoluminal graft placement
First Claim
1. A method for introducing a vascular graft into a primary artery which divides into first and second branch arteries, said method comprising:
- introducing and deploying a bifurcated structure including an anchor section and first and second connector sections so that the anchor section is disposed within the primary artery and the first and second connector sections extend toward the first and second branch arteries and thereafter;
introducing a first tubular graft into the first connector section and anchoring said first tubular graft to extend between the first connector section and the first branch artery to form a first continuous flow path from the primary artery to the first branch artery; and
introducing a second tubular graft into the second connector section and anchoring said second tubular graft to extend between the second connector section and the second branch artery to form a second continuous flow path from the primary artery to the second branch artery.

Abstract
A vascular graft comprises a perforate tubular compressible frame having a fabric liner disposed over at least a portion of the frames lumen. The graft may be used in combination with a base structure to form a bifurcated graft in situ. The base structure compresses a compressible frame having a fabric liner which defines a pair of divergent legs. The base structure is positioned within the aorta so that one leg enters each iliac. The tubular grafts can then be introduced into each leg to form the bifurcated structure. A graft delivery catheter includes a controllably flared sheath which facilitates recapture of a partially deployed graft.

15. A method for treating an aneurysm by introducing a vascular graft into a primary artery which branches into first and second branch arteries, said method comprising:
-
introducing into a patient'"'"'s vasculature an anchor section and first tubular graft of the vascular graft so that the anchor section is disposed within the primary artery and the first tubular graft is at least partially disposed within the first branch artery to form a first continuous flow path from the primary artery to the first branch artery; and securing a second tubular graft to the anchor section via a connector leg of the anchor section to form a second continuous flow path from the primary artery to the second branch artery, wherein each of the grafts comprises a tubular frame and a liner. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
