Abstract:
1. An endoluminal prosthesis deployment system for deploying an endoluminal prosthesis having at least a main branch portion and a first branch portion, comprising: a flexible catheter body comprising an outer sheath with a proximal and distal end, an inner core that extends through the outer sheath and is axially moveable with respect to the outer sheath; a main branch restraint that surrounds and constrains at least the main branch portion of the prosthesis, the main branch restraint having a proximal portion adjacent to a proximal end of the main branch portion of the prosthesis, a distal portion adjacent a distal end of the main branch portion of the prosthesis, and an intermediate portion positioned between the proximal and distal portions of the main branch restraint; a plurality of segments between perforations in the main branch restraint along the length of at least a portion of one side of the main branch restraint, wherein at least one of the perforations is positioned closer to the distal portion of the main branch restraint than another of the perforations; a release wire extending through at least two of said perforations and looped around a segment of said plurality of segments between said at least two of said perforations; and a first branch restraint comprising a tubular member coupled to a first branch release mechanism; wherein:
