Method for deploying bifurcated graft using a multicapsule system
First Claim
1. A system for providing support to a wall of a graft that has a first end, a second end, a medial portion and devices that attach the graft within vasculature, comprising:
- a support system having a compressed configuration and an expanded configuration, said support system configured to act independently of the devices that attach the graft within vasculature and to be permanently placed within the medial portion of the graft to resist kinking of the graft; and
a catheter configured for transporting said support system through a patient'"'"'s vasculature and for delivering said support system within an interior of the medial portion of the graft that has been implanted within vasculature.

Abstract
An intraluminal grafting system having a balloon catheter assembly, a capsule catheter assembly and capsule jacket assembly is used for deploying in the vessel of an animal body a bifurcated graft having a plurality of attachment systems. The deployment catheters contain an ipsilateral capsule assembly, a contralateral capsule assembly and a distal capsule assembly, wherein the attachment systems of the bifurcated graft are disposed within the three capsule assemblies. A removable sheath of the capsule jacket assembly covers the bifurcated graft and capsule assemblies to provide a smooth transition along the length of the deployment catheters. The bifurcated graft is comprised of a main tubular member and two tubular legs, having attachment systems with wall engaging members secured to the superior end of the main tubular member and the inferior ends of the tubular legs. An inflatable membrane configured on the balloon catheter is used to firmly implant the attachment systems within the vessel. The bifurcated graft and attachment systems are configured to remain in the vessel after the deployment catheters are withdrawn. The method of use of the present intraluminal grafting system is also disclosed, for example, for deploying a bifurcated graft proximate the abdominal aortic bifurcation.

22. A method for providing support to a wall of a graft, comprising the steps of:
-
implanting a graft within a patient'"'"'s vasculature at a repair site, the graft having a medial portion and devices that attach the graft within vasculature;
subsequent to implanting the graft within vasculature, advancing a catheter carrying a support system within the patient'"'"'s vasculature and to the repair site;
causing the catheter to release the support system within an interior of the graft; and
configuring the support system to be permanently placed within the medial portion of the graft so that the support system acts independently of the devices that attach the graft within vasculature.
