1. An implantable endoprosthesis delivery system, comprising:
- a tube having an outer surface;
a coil at least partially surrounding the tube, the coil comprising a first portion having an inner surface, a second portion, and a third portion, the first portion being positioned between the second and third portions, the inner surface of the first portion of the coil being spaced outwardly from the outer surface of the tube and the second and third portions of the coil being in contact with an outer surface of the tube;
a sheath surrounding and being slidable relative to the tube and the coil, the sheath and the tube being configured so that an implantable endoprosthesis can be disposed between the sheath and the tube;
an implantable endoprosthesis disposed between the sheath and the tube;
a bumper disposed on the tube and positioned between the endoprosthesis and the coil;
wherein the sheath surrounds the first portion of the coil; and
wherein the first portion of the coil is in contact with the sheath.
