Abstract
A tandem modular endograft includes a main elongate tubular graft body having at least one circumferential inflatable channel disposed towards a proximal portion of the graft body wall and a plurality of circumferential inflatable channels disposed towards a distal portion of the graft body wall. A proximal expansion anchor is disposed at or secured to a proximal neck portion of the graft body wall. First and second elongate tubular stent-graft extensions may be percutaneously disposed into a distal end of the tubular graft body. In combination, proximal portions of the first and second stent-graft extensions are conformable to a shape of the open lumen of the main graft body.

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.

- the graft body wall comprising a proximal portion disposed at the proximal open end;
- the graft body wall comprising at least one proximal circumferential inflatable channel disposed towards the proximal portion of the graft body wall near the proximal open end of the main tubular graft body and distally prior the proximal portion of the graft body wall;
- the graft body wall comprising a plurality of distal circumferential inflatable channels disposed towards the distal portion of the graft body wall near the distal open end of the main tubular graft body at least one of the plurality of distal circumferential inflatable channels disposed near but proximal to the distal open end of the main elongate tubular graft body;
- a first and second elongate tubular stent-graft extensions separate from the main graft body, percutaneously disposed into the distal end of the 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 a proximal portions, distal portions and open lumens therein between;
- wherein each of the plurality of distal circumferential inflatable channels 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 end of the tubular graft body, wherein the plurality of distal circumferential inflatable channels causes the first and second stent-graft extensions to be secured to each other and to the main graft body at the distal end of the tubular graft body when the plurality of the distal circumferential inflatable channels is in an inflated state.
