Endoluminal prosthesis with steerable branch
First Claim
1. An endoluminal prosthesis system comprising:
- a main graft body, the main graft body comprising;
a sidewall,a proximal end, anda distal end;
a first stent positioned near the proximal end of the main graft body, and a second stent positioned adjacent to and distal of the first stent, each of the first stent and the second stent comprising a series of peaks and a series of valleys;
an opening in the sidewall positioned longitudinally between one of the peaks of the first stent and one of the valleys of the second stent; and
a tubular branch attached to the main graft body, the tubular branch comprising a first end opening and a second end opening, the tubular branch extending from the opening and attached to the main graft body at the opening at a point of attachment about a circumference of the tubular branch, the tubular branch being flexibly orientable between a retrograde configuration and an antegrade configuration, wherein, in the retrograde configuration, the first end opening is oriented toward the distal end of the main graft body and the second end opening is oriented toward the proximal end of the main graft body, and, in the antegrade configuration, the first end opening is oriented toward the proximal end of the main graft body and the second end opening is oriented toward the distal end of the main graft body;
a third stent positioned near the proximal end of the main graft body, the third stent comprises a greater number of peaks and valleys than the first stent, the third stent is positioned proximal of the first stent, and the first stent and the third stent are in a nested relationship with one another; and
wherein the proximal end of the main graft body comprises a slanted end, and a top longitudinal length of the main graft body is longer than a bottom longitudinal length of the main graft body to form the slanted end.

Abstract
An endoluminal prosthesis may include a tubular main graft body including a sidewall and proximal and distal ends. A first stent may be positioned near the proximal end of the main graft body. A second stent may be positioned adjacent to and distal of the first stent. An opening in the sidewall may be positioned longitudinally between a peak of the first stent and a valley of the second stent. A tubular branch may be disposed in the opening. The branch may include first and second end openings. The branch may be flexibly orientable between a retrograde configuration in which the first end opening is oriented toward the distal end and the second end opening is oriented toward the proximal end and an antegrade configuration in which the first end opening is oriented toward the proximal end and the second end opening is oriented toward the distal end.
