APPARATUS AND METHOD OF PLACEMENT OF A GRAFT OR GRAFT SYSTEM
First Claim
1. An endoluminal prosthesis, comprising:
- a first stent portion and a second stent portion;
a main graft body comprising a first portion, a second portion, and a third portion, the second portion having a cross-sectional size that is significantly larger than a cross-sectional size of the first portion or the third portion, and also significantly larger than a cross-sectional size of the target vessel; and
one or more openings formed in the second portion of the main graft body;
wherein;
the first portion of the main graft body is attached to the first stent portion and wherein the third portion of the main graft body is attached to the second stent portion; and
the second portion of the main graft body is not directly attached to the first stent portion, the second stent portion, or any other internal support structure.

Abstract
Some embodiments relate to endoluminal prostheses having a first stent portion and a second stent portion, a main graft body comprising first, second, and third portions, the second portion having a cross-sectional size that is significantly larger than a cross-sectional size of the first or third portions, and also significantly larger than a cross-sectional size of the target vessel. In some embodiments, the first portion of the main graft body can be attached to the first stent portion and the third portion of the main graft body can be attached to the second stent portion. The prostheses can be configured such that the second portion of the main graft body is not directly attached to the first stent portion, the second stent portion, or any other internal support structure. In some embodiments, one or more openings can be formed in the second portion of the main graft body.

21. An endoluminal prosthesis, comprising:
-
a main graft body comprising a first portion, a second portion, and a third portion, the entirety of the second portion having a cross-sectional size that is significantly larger than a cross-sectional size of the first portion or the third portion, and also significantly larger than a cross-sectional size of the target vessel; a support member positioned within the main graft body, the support member having a first support portion, a second support portion, and a third support portion; and one or more openings formed in the second portion of the main graft body; wherein; the first portion of the main graft body is attached to the first support portion of the support member at a first number of attachment points; the second portion of the main graft body is attached to the second support portion of the support member at a second number of attachment points; the third portion of the main graft body is attached to the third support portion of the support member at a third number of attachment points; and the third number of attachment points is less than the first number of attachment points and the third number of attachment points. - View Dependent Claims (22, 23, 24, 25, 26)

27. A method of deploying an endoluminal prosthesis, comprising:
-
advancing a catheter supporting the endoluminal prosthesis therein through a patient'"'"'s vasculature to a target vessel location, wherein; the prosthesis has a main graft body comprising a first portion, a second portion, and a third portion; and the second portion of the main graft body has a cross-sectional size that is significantly larger than a cross-sectional size of the first portion and the third portion, and also significantly larger than a cross-sectional size of the target vessel; advancing one or more catheters through one or more fenestrations formed in the main graft body and into one or more branch vessels in the patient'"'"'s vasculature; at least partially expanding at least the second portion of the main graft body; and substantially aligning the one or more fenestrations formed within the second portion of the main graft body with the one or more branch vessels by moving the one or more fenestrations in a circumferential and/or axial direction toward an ostium of the one or more branch vessels. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35)
