1. A prosthesis delivery system comprising:

  • a self-expandable stent-graft prosthesis with a first end, a second end and a length therebetween; and

    a deployment device comprising;

    an elongated outer sheath, the elongated outer sheath overlying the self-expandable stent-graft prosthesis and maintaining the first end of the self-expandable stent-graft prosthesis in a radially compressed state, said elongated outer sheath being retractable with respect to the self-expandable stent-graft prosthesis for radial self-expansion of the first end of the self-expandable stent-graft prosthesis from the radially compressed state upon retraction of the elongated outer sheath; and

    a retaining member, the retaining member overlying and maintaining the second end of the self-expandable stent-graft prosthesis in a radially compressed state, the second end of the self-expandable stent-graft prosthesis being positioned inside the retaining member, the retaining member being independently retractable from the second end of the self-expandable stent-graft prosthesis for radial self-expansion of the second end of the self-expandable stent-graft prosthesis from the radially compressed state upon retraction of the retaining member;

    wherein only the elongated outer sheath maintains the first end of the self-expandable stent-graft prosthesis in the radially compressed state and only the stent-graft retaining member maintains the second end of the self-expandable stent-graft prosthesis in the radially compressed state, and the retaining member and the elongated outer sheath are retractable in opposite directions.
