1. A branched prosthesis comprising:
- a tubular body of biocompatible graft material having,a first end,a first portion,a second end,a second portion,a lumen between the first and second ends,a sidewall between the first and second ends,a first fenestration in the side wall in the first portion and having an internal branch attached to the side wall at the fenestration and extending from the fenestration into the lumen, the internal branch having a first end communicating with the fenestration and a second end having an opening extending toward the first end;
at least one second fenestration in the sidewall spaced axially from the first fenestration and having an external branch attached to the side wall at the fenestration and extending from the side wall with a first end communicating with the fenestration and a second end extending toward the second end; and
a plurality of stents attached along the length of the tubular body.

Abstract
An endoluminal prosthesis comprises a prosthetic trunk having a trunk lumen and a trunk wall, a first prosthetic branch having a first branch lumen and a branch wall, and a second prosthetic branch having a second branch lumen. The first branch lumen and the second branch lumen are both in fluid communication with the trunk lumen through the trunk wall and the second branch lumen is in fluid communication with the first branch lumen through the branch wall. Additional devices, systems, and methods are disclosed.

8. A branched prosthesis comprising:
-
a tubular body of biocompatible graft material having, a proximal end, a proximal portion, a distal end, a distal portion, a lumen between the proximal and distal ends, a sidewall between the proximal and distal ends, a first fenestration in the side wall in the proximal portion and having an internal branch attached to the side wall at the fenestration and extending from the fenestration into the lumen, the internal branch having a first end communicating with the fenestration and a second end having an opening extending toward the proximal end; at least one second fenestration in the sidewall distal of the first fenestration and having an external branch attached to the sidewall at the fenestration and extending from the side wall with a first end communicating with the fenestration and a second end extending toward the distal end; and a plurality of stents attached along the length of the tubular body. - View Dependent Claims (9, 10, 11, 12, 13)

14. A branched stent graft comprising:
-
a tubular body of biocompatible graft material having, a proximal end, a distal end, a lumen between the proximal and distal ends, a sidewall between the proximal and distal ends, at least two branches attached to the sidewall and extending from the side wall, each having an end opening pointing toward the proximal end of the tubular body; at least one branch attached to the sidewall and extending from the sidewall and having an end opening pointing toward the distal end of the tubular body, wherein at least one of the proximally pointing branches is an internal branch, and wherein the tubular body and the branches each comprise at least one stent. - View Dependent Claims (15, 16, 17)
