1. A device for deploying a stent-graft within a body lumen comprising:

  • an outer tubular member defining an outer lumen;

    an intermediate tubular member at least partially disposed within the outer lumen and configured to move axially therein, wherein the intermediate tubular member defines an intermediate lumen;

    an inner tubular member at least partially disposed within the intermediate lumen and configured to move axially therein;

    a self-expanding stent-graft disposed in the outer lumen and at least partially overlying the intermediate member, wherein the stent-graft is configured to move axially in cooperation with the intermediate member;

    a stent lock substantially disposed from a distal end to a proximal end thereof directly on the intermediate tubular member, wherein the stent lock is configured to releasably couple the stent-graft and the intermediate tubular member and is configured to be cylindrically shaped in an unconstrained configuration; and

    a tubular member lock configured to releasably couple the inner tubular member and the outer tubular member such that, when the inner tubular member and the outer tubular member are coupled, movement of the outer tubular member in an axial direction results in movement of the inner tubular member in the axial direction with respect to the intermediate tubular member so as to deploy the stent-graft.
