1. A device for grafting a prosthesis to a wall of a lumen, said device comprising:

  • a) a tubular introducer sheath having a longitudinal bore;

    b) a prosthesis comprising a tubular graft having a longitudinal bore and disposed in the longitudinal bore of said tubular introducer sheath, said graft being expandable radially to substantially conform to an interior wall of a lumen;

    a self expanding spring assembly having a compressed state and attached to said tubular graft for expanding said graft so that it substantially conforms to an interior wall of a lumen after said introducer sheath has been removed from said self expanding spring assembly, said introducer sheath containing said self expanding spring assembly in said compressed state when said spring assembly is positioned in said longitudinal bore of said introducer sheath; and

    anchoring means for attaching said graft to an interior wall of a lumen;

    c) tubular carrier means having a longitudinal bore and disposed in the longitudinal bore of said tubular graft, said carrier means also having a plurality of apertures;

    d) central control means for maintaining an axial position of said prosthesis during removal of said introducer sheath, said central control means being disposed in the longitudinal bore of said tubular carrier means; and

    e) mooring loops engaging said prosthesis and passing through said apertures in said tubular carrier means to engage said central control means.
