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 having a smaller cross-sectional dimension than the first superior portion, and a first lumen through the first superior and first inferior portions, the first superior portion having a convexly curved first outer wall and a first septal wall that define a substantially D-shaped cross-section;
a second endograft device having a second superior portion, a second inferior portion having a smaller cross-sectional dimension than the second superior portion, and a second lumen through the second superior and second inferior portions, the second superior portion having a convexly curved second outer wall and a second septal wall that define a substantially D-shaped cross-section; and
wherein the first and second endograft devices are configured to self-expand into an expanded configuration via inherent hoop force of the first and second endograft devices such that 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.

12. A modular endograft system, comprising:
-
a first endograft device having a first superior portion with a first distal section, a first inferior portion, and a first lumen through the first superior and first inferior portions, the first superior portion having a convexly curved first outer wall and a first septal wall that define a substantially D-shaped cross-section; a second endograft device having a second superior portion with a second distal section, a second inferior portion, and a second lumen through the second superior and second inferior portions, the second superior portion having a convexly curved second outer wall and a second septal wall that define a substantially D-shaped cross-section; and wherein the first and second endograft devices are longitudinally staggered with respect to each other such that the first distal section of the first endograft device is positioned superiorly relative to the second distal section of the second endograft device. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A modular endograft system comprising:
-
a first endograft device having a first superior portion, a first inferior portion having a smaller cross-sectional dimension than the first superior portion, a first braided frame, and a first lumen through the first superior and first inferior portions, the first superior portion having a substantially D-shaped cross-section; a second endograft device having a second superior portion, a second inferior portion having a smaller cross-sectional dimension than the second superior portion, a second braided frame, and a second lumen through the second superior and second inferior portions, the second superior portion having a substantially D-shaped cross-section; wherein the first and second braided frames are configured to have substantially continuous longitudinal support along the superior and inferior portions of the first and second endograft devices, respectively; and wherein the first and second superior portions press against each other and form a septum between the first and second lumens. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)

29. A method of treating an aneurysm located in a primary vessel before a bifurcation into a first vessel and a second vessel, comprising:
-
positioning a first endograft device relative to the aneurysm such that at least a segment of a first superior portion of the first endograft device is positioned superior to the aneurysm and a first inferior portion of the first endograft device extends at least partially through the aneurysm, the first superior portion having a convexly curved first outer wall and a first septal wall that define a substantially D-shaped cross-section; positioning a second endograft device relative to an aneurysm such that at least a segment of a second superior portion of the second endograft device is positioned superior to the aneurysm and a second inferior portion of the second endograft device extends at least partially through the aneurysm, the second superior portion having a convexly curved second outer wall and a second septal wall that define a substantially D-shaped cross-section, and wherein the second endograft device is positioned independently of positioning the first endograft device; deploying the first endograft device from a first catheter and deploying the second endograft device from a second catheter such that the first and second superior portions self-expand to an expanded configuration in which the first and second septal walls press against each other via an inherent spring force to form a septum between the first and second lumens. - View Dependent Claims (30, 31, 32, 33, 34, 35)
