ABSTRACT:
A stent-graft device for placement in the aortic arch comprises a graft having a main body sized for insertion in the aortic arch and defining a central lumen, the graft including a left branch and a right branch attached to the main body and arranged for flow communication with the central lumen, each of the main body, the left branch and the right branch including a stent and shiftable between a narrowed undeployed configuration and an expanded deployed configuration. The left and right branches each branch include a sheath arranged to constrain the branches in the undeployed configuration, and the left and right branches are arranged to be pulled into the left or right brachiocephalic artery exclusively under tension by respective pull wires. An inner sheath is arranged to constrain the main body of the graft in the undeployed configuration, and an outer sheath is arranged to constrain each of the left branch and the right branch in a folded position generally adjacent the main body when each of the left branch and the right branch is in the undeployed configuration.
