Abstract
An endoluminal prosthesis system includes a graft having a tubular body with a proximal end and a distal end. A lumen extends from the proximal end to the distal end. A proximal portion of the graft includes the proximal end; a distal portion of the graft includes the distal end; and a middle portion of the graft extends from the proximal portion to the distal portion. A plurality of connection branches are attached to the middle portion. Each of the connection branches has an inner opening at an inner end attached to the middle portion and an outer opening at an outer end disposed radially outwardly from the inner end. Each of the connection branches is pivotable in a proximal and distal direction and a circumferential direction relative to the middle portion. Further, each of the connection branches includes an expandable seal stent at the outer end.
