<p>A graft deployment system (320), comprises an elongate, flexible catheter body, having a proximal end and a distal end and comprising an outer sheath (328) and an inner core (330) that is axially moveable with respect to the outer sheath (328). A main vessel graft restraint comprising a first peelable cover (400) for restrains a main vessel portion (392) of a graft (390). In a bifurcated graft (390), a first branch vessel graft restraint (411) restrains a first branch vessel portion (394) of the graft. A second branch vessel graft restraint (412) restrains a second branch vessel portion (396) of the graft. The first peelable cover (400) is coupled to a main branch release element (355) and wherein each of the main vessel graft restraint (400), first branch vessel graft restraint (411), and the second branch vessel graft restraint (412) are positioned within the catheter body in a graft loaded condition.</p> |
