Abstract
An endoluminal prosthesis system for being deployed in a patient's aorta near the heart includes a graft having a tubular body with a lumen extending from proximal end configured to be deployed near a patient's heart to a distal end configured to be deployed away from the patient's heart. A collar around the graft is sized and configured to be sutured to a patient's aorta. Passageways in the middle portion of the graft permit fluid communication from the lumen of the graft to an exterior of the graft. A respective bridging branch is disposed at each of the passageways, each of the bridging branches having an inner opening and an outer opening so that the bridging branches provide fluid communication from the lumen of the graft to the exterior of the graft. A respective bridging graft is sized and arranged to mate with each of the bridging branches.
