MODULAR ENDOGRAFT DEVICES AND ASSOCIATED SYSTEMS AND METHODS
First Claim
1. A modular endograft system, comprising:
- a first endograft device having a first superior portion, a first inferior portion, and a first lumen through the first superior and inferior portions, wherein the first superior portion has a first superior terminus, a first outer wall, and a first septal wall;
a second endograft device having a second superior portion, a second inferior portion, and a second lumen through the second superior and inferior portions, wherein the second superior portion has a second superior terminus, a second outer wall, and a second septal wall;
wherein the first and second septal walls of the first and second endograft devices press against one another and form a septum; and
wherein the first superior terminus of the first endograft device is superior to the second superior terminus of the second endograft device such that the first and second endograft devices are longitudinally staggered and a free end portion of the first superior portion is positioned distally beyond the second superior terminus.

Abstract
Modular endograft devices and associated systems and methods are disclosed herein. In several embodiments, an endograft system can include a first endograft device and a second endograft device that each include an integrated frame, a cover and a lumen within the cover. Each endograft device further includes a superior portion and an inferior portion. The superior portion can have a convexly curved outer wall and a septal wall. The first and second endograft devices can be configured to extend into a low-profile configuration with a first cross-sectional dimension and a first length and self-expand into an expanded configuration with a second cross-sectional dimension greater than the first cross-sectional dimension and a second length less than the first length. In the expanded configuration, the septal walls can press against each other and form a septum between the lumens of the first and second endograft devices.

17. A modular endograft system, comprising:
-
a first endograft device having a first frame, a first cover attached to the first frame, and a first lumen within the first cover, wherein the first frame and the first cover have a first superior portion and a first inferior portion, and the first superior portion has a convexly curved first outer wall and a first septal wall; a second endograft device having a second frame, a second cover attached to the second frame, and a second lumen within the second cover, wherein the second frame and the second cover have a second superior portion and a second inferior portion, the second superior portion having a convexly curved second outer wall and a second septal wall; wherein the first and second endograft devices are configured to be extended into a low-profile configuration with a first cross-sectional dimension and expand to an expanded configuration with a second cross-sectional dimension greater than the first cross-sectional dimension such that in the expanded configuration opposing portions of the first and second septal walls press against each other and form a septum between the first and second lumens; and wherein the first and second endograft devices are longitudinally staggered with respect to the each other in the expanded configuration such that the first frame includes a first free end portion projecting distally beyond the second superior portion of the second endograft device. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)

26. A method of repairing an aneurysm in a primary blood vessel before a bifurcation into a first blood vessel and a second blood vessel, comprising:
-
advancing a first endograft device through the first blood vessel to a target site in the primary blood vessel before the aneurysm; advancing a second endograft device through the second blood vessel to the target site independently of advancing the first endograft device through the first blood vessel; deploying the first and second endograft devices at the target site by separately expanding the first and second endograft devices to an expanded configuration such that opposing portions of first and second septal walls of the first and second endograft devices, respectively, press against each other to form a septum between the first and second endograft devices; and wherein a first superior portion of the first endograft device is longitudinally staggered relative to a second superior portion of the second endograft device such that a free end portion of the first superior portion projects distally beyond a terminus of the second endograft device. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
