1. A branched and fenestrated prosthesis comprising:
- a tubular body of biocompatible graft material having,a first end,a first cylindrical portion having a first diameter,a second end,a second cylindrical portion having a second diameter,a lumen between the first and second ends,a tapered portion between the first and second cylindrical portions and tapering from the first diameter to the second diameter,a sidewall between the first and second ends,a branch in the side wall in the tapered portion at least partially externally of the tubular body, the branch having a first end communicating with the lumen and a second end having an opening extending toward the second end;
a fenestrated region in the second cylindrical portion comprising a first unbranched fenestration in the sidewall spaced axially from the branch and a second unbranched fenestration in the sidewall spaced axially from the branch and circumferentially offset from the first unbranched fenestration; 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.

11. A branched and fenestrated prosthesis comprising:
-
a tubular body of biocompatible graft material having, a proximal inflow end, a proximal cylindrical portion having a first diameter, a distal outflow end, a distal cylindrical portion distal to the first cylindrical portion and having a second diameter, a lumen between the first and second ends, a tapered portion between the proximal and distal cylindrical portions and tapering from the first diameter to the second diameter, a sidewall between the proximal and distal ends, a branch in the side wall in the tapered portion extending from the fenestration and at least partially externally of the tubular body, the branch having a first end communicating with the lumen and a second end having an opening extending toward the distal outflow end; a fenestrated region in the distal cylindrical portion comprising a first unbranched fenestration in the sidewall spaced distally of the branch, a second unbranched fenestration in the sidewall spaced distally of the branch and circumferentially offset from the first unbranched fenestration; and a plurality of stents attached along the length of the tubular body. - View Dependent Claims (12, 13, 14, 15)
