1. A vascular connector deployment tool, comprising:
a handle;
an elongated mandrel extending distally from the handle, the mandrel having a proximal end coupled to the handle, a distal end and an outer surface;
a vascular connector having a proximal circumferential portion and a distal circumferential portion disposed over a portion of the mandrel distal end, the vascular connector being expandable from a first insertion diameter to a second deployed diameter and has a structure that allows for expansion from the first insertion diameter to the second deployed diameter, the structure being configured to hold the vascular connector securely inside a blood vessel and a graft in the deployed state;
a retractable sheath assembly including a translucent retractable outer sheath telescopically deployed over a retractable inner sheath that is visible through the outer sheath, wherein the inner and outer sheaths of the retractable sheath assembly are configured to constrain the vascular connector against the outer surface of the mandrel in an insertion profile and wherein a distal transition between the outer sheath and the inner sheath visually indicates position of the vascular connector; and
a single actuator on the handle, the single actuator being configured as a slider having a longitudinal range of motion in a slot on the handle, the slider being mechanically coupled to both the outer sheath and the inner sheath to initially retract only the outer sheath relative to the mandrel to expose the distal circumferential portion of the vascular connector and cause the distal circumferential portion to expand from the first insertion diameter to the second deployed diameter, and to subsequently retract the outer sheath and the inner sheath relative to the mandrel to expose the proximal circumferential portion of the vascular connector and cause the proximal circumferential portion to expand from the first insertion diameter to the second deployed diameter.
