1. A controlled stent-graft deployment delivery system, comprising:

  • a stent-graft;

    a retractable primary sheath containing said stent-graft in a first constrained diameter configuration;

    an outer tube within the retractable primary sheath and within the stent-graft;

    an inner tube within the outer tube, wherein the inner tube and the outer tube both axially can move relative to the retractable primary sheath and to each other;

    a cap coupled to a distal end of the inner tube and configured to retain at least a portion of a proximal portion of the stent-graft in a radially compressed configuration, wherein a controlled relative axial movement between the outer tube and the inner tube releases the proximal end of the stent-graft from the cap and from the radially compressed configuration.
