1. A modular endovascular graft assembly comprising:
a main elongate tubular graft body having a proximal open end and an opposed distal open end, defining a graft body wall having a proximal portion, a medial portion, a distal portion, and an open lumen therein between;
a proximal expansion anchor disposed at or secured to a proximal neck portion disposed at the proximal portion of the graft body wall;
a first and second elongate tubular stent-graft extensions percutaneously disposed into the distal open end of the main tubular graft body, the first and second stent-graft extensions having respective proximal open ends and opposed distal open ends, defining graft body walls having proximal portions, medial portions, distal portions, and open lumens therein between;
wherein, in combination, the proximal portions of the first and second stent-graft extensions are conformable to a shape of the open lumen of the main graft body; and
wherein the graft body wall of the main tubular graft body further comprises:
at least one circumferential inflatable channel disposed near but proximal to the distal open end of the main tubular graft body, wherein each of the at least one circumferential inflatable channel surrounds both the first and second elongate tubular stent-graft extensions when the first and second elongate tubular stent-graft extensions are percutaneously disposed into the distal open end of the main tubular graft body, causing the first and second stent-graft extensions to be secured to each other and to the graft body wall at the distal open end of the main tubular graft body when the at least one circumferential inflatable channel disposed near the distal portion of the main tubular graft body is in an inflated state.
