1. A kit of parts for the delivery of a stent within a body lumen comprising:

  • a. an elongated sheath having proximal and distal ends, an outer lumen extending therein, a first port in the distal end, said first port being in fluid communication with the outer lumen;

    b. an elongated catheter adapted to be disposed within the outer lumen of the sheath and having proximal and distal ends, said elongated catheter having an outer member, an expandable member proximally adjacent to the distal end of the outer member which is adapted to receive on the exterior thereof an expandable stent, an inner lumen within said inner member which is adapted to receive a guiding member therein and which extends the entire length of said inner lumen;

    c. an elastic cone having a proximal end and a distal end, having a small aperture in said distal end fitted about the distal end of said catheter and a large aperture in said proximal end releasably fitted about the distal end of said sheath; and

    d. means to adjust the relative axial positions of the catheter and the sheath to expose the expandable member so that upon the expansion thereof an expandable stent disposed about the expandable member will thereby be expanded.
