Abstract
Abstract A endovascular graft having at least two thin wall graft members, with at least one of the thin wall graft members configured to be deployed within a lumen of another thin wall graft member. The thin wall graft members may be coupled or connected to each other so as to allow relative axial displacement of the sections, or they may be separate members that have dimensions and a configuration to allow coaxial deployment within inner lumens of each other. By having multiple thin wall graft member, the graft may be built up within a patient's vasculature in steps through a delivery catheter system that is smaller in profile and more flexible than a delivery catheter system configured to deliver a single component graft. The graft of the invention may be delivered percutaneously or intraoperatively.

Claim 9
Dependent Claim
69 words
8 . The graft of claim 1 wherein each thin wall graft member further comprises an anchoring mechanism at both ends and at least two of the thin wall graft members have a longitudinal length sufficient to span the preselected length of the patient's body lumen and engage tissue of sufficient integrity to support the anchoring mechanisms at both ends of the at least two thin wall graft members.
Claim 10
Dependent Claim
134 words
9 . A method of deploying an endovascular graft within a body passageway of a patient comprising: a) providing an endovascular graft comprising at least two thin wall graft members configured to be layered in a deployed state; b) percutaneously delivering a first thin wall graft member through a low profile delivery catheter system to a desired site within a passageway of a patient's body and deploying the first thin wall graft member at the desired site; c) percutaneously delivering a second thin wall graft member through a low profile delivery catheter system and positioning the second thin wall graft member within a longitudinal lumen of the deployed first thin wall graft member; and d) deploying the second thin wall graft member within the longitudinal lumen of the deployed first thin wall graft member.
Claim 11
Dependent Claim
134 words
9 . A method of deploying an endovascular graft within a body passageway of a patient comprising: a) providing an endovascular graft comprising at least two thin wall graft members configured to be layered in a deployed state; b) percutaneously delivering a first thin wall graft member through a low profile delivery catheter system to a desired site within a passageway of a patient's body and deploying the first thin wall graft member at the desired site; c) percutaneously delivering a second thin wall graft member through a low profile delivery catheter system and positioning the second thin wall graft member within a longitudinal lumen of the deployed first thin wall graft member; and d) deploying the second thin wall graft member within the longitudinal lumen of the deployed first thin wall graft member.
