1. A modular endovascular graft assembly, comprising:

  • a bifurcated main graft member formed from a supple graft material including a main fluid flow lumen therein, an ipsilateral leg with an ipsilateral fluid flow lumen in communication with the main fluid flow lumen, a contralateral leg with a contralateral fluid flow lumen in communication with the main fluid flow lumen and a network of inflatable channels disposed on the main graft member including the ipsilateral and contralateral legs which is configured to accept a hardenable fill material to provide structural rigidity to the main graft member when the network of inflatable channels are in an inflated state and which includes at least one inflatable cuff disposed on a proximal portion of the main graft member configured to seal against an inside surface of a patient'"'"'s vessel;

    a proximal anchor member which is formed from a single piece of material, which is disposed at a proximal end of the main graft member, which is secured to the main graft member and which includes a self-expanding proximal stent portion, a self-expanding distal stent portion, and struts that are disposed between adjacent crowns of respective proximal stent portions and distal stent portions, said struts including a cross sectional area that is the same as or greater than a cross sectional area of either proximal stent portions or distal stent portions adjacent each strut and configured to avoid stress and strain concentrations at junctions between the self-expanding distal stent portion and the self-expanding proximal stent portion;

    at least one ipsilateral graft extension including a fluid flow lumen disposed therein with the fluid flow lumen of the graft extension sealed to and in fluid communication with the fluid flow lumen of the ipsilateral leg of the main graft member; and

    at least one contralateral graft extension including a fluid flow lumen disposed therein with the fluid flow lumen of the graft extension sealed to and in fluid communication with the fluid flow lumen of the contralateral leg of the main graft member.
