1. A catheter carrying a self-expanding helical prosthesis, said catheter comprising:

  • a catheter body having a proximal end and a distal end;

    a barrel rotatably attached to the distal end of the catheter body;

    a self-expanding helical prosthesis disposed over the barrel; and

    an axially retractable cover disposed over said helical prosthesis, said cover maintaining the prosthesis in a radially reduced diameter condition;

    wherein axial retraction of the cover allows the prosthesis to expand radially and wherein the barrel rotates as the prosthesis is deployed in a lumen which immobilizes a first released end of the stent.
