Abstract
A method of deploying a stent graft includes radially constraining proximal apexes of a proximal anchor stent ring of the stent-graft in a space between merlons of a castellated sleeve of a tip and a spindle having spindle pins, the proximal apexes extending around the spindle pins. A graft material of the stent-graft is radially constrained in a primary sheath, a proximal end of the graft material being attached to distal apexes of the proximal anchor stent ring. The proximal anchor stent ring further includes struts extending between the proximal apexes and the distal apexes. The primary sheath is retracted to allow the proximal end of the graft material and the distal apexes of the proximal anchor stent ring to pivot out beyond the confines of the sleeve to a large angle as the proximal end radially expands. The struts then extend through embrasures of the castellated sleeve. The tip is advanced to deploy the proximal apexes.
