MODULAR ENDOGRAFT DEVICES AND ASSOCIATED SYSTEMS AND METHODS
First Claim
1. A modular endograft system, comprising:
- a first endograft device having an integrated first frame (“
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 first outer wall and a first septal wall;
a second endograft device having an integrated second frame (“
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 second outer wall and a second septal wall; and
wherein the first and second endograft devices are configured to be extended into a low-profile configuration with a first cross-sectional dimension and a first length and self-expand to an expanded configuration with a second cross-sectional dimension greater than the first cross-sectional area and a second length less than the first length such that in the expanded configuration the first and second septal walls press against each other and form a septum between the first and second lumens.

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.

36. A method of repairing an aneurysm in a primary blood vessel before the primary blood vessel bifurcates into a first blood vessel and a second blood vessel, the method comprising:
-
advancing a first endograft device through the first blood vessel to a target site in the primary blood vessel to a target site before the aneurysm, wherein the first endograft device includes a first frame, a first cover, 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, the first superior portion having a first outer wall and a first septal wall; advancing a second endograft device through the second blood vessel to the target site, wherein the second endograft device includes a second frame, a second cover, 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, and the second superior portion having a second outer wall and a second septal wall; deploying the first and second endograft devices at the target site such that the first and second endograft devices self-expand to an expanded configuration via inherent hoop forces in the first and second frames such that the first and second septal walls press against each other to form a septum between the first and second lumens, the first and second outer walls press against a vessel wall of the primary blood vessel; and wherein the first and second endograft devices are positioned independently of one another. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44)
