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.
