Claim 9:
10. A vascular graft deployment tool having a longitudinal axis, comprising:
a grip;
an elongated mandrel positioned distal of the grip;
a vascular graft having a distal portion and a proximal portion, at least part of which is disposed coaxially about the mandrel;
a sheath configured to be withdrawn proximally that constrains the vascular graft against the mandrel in an insertion diameter; and
an actuator that is moveable relative to the grip and engages the sheath assembly, wherein a first operation of the actuator from an initial position over a predetermined longitudinal range of motion along the longitudinal axis of the deployment tool causes withdrawal of the sheath to free only the distal portion of the vascular graft allowing expansion of the distal portion of the vascular graft from its constrained position and, after the actuator returns to its initial position, a second operation of the actuator over the predetermined longitudinal range of motion along the longitudinal axis of the deployment tool causes further withdrawal of the sheath to free the proximal portion of the vascular graft allowing expansion of the proximal portion of the vascular graft from its constrained position.
