1. A catheter delivery device for a self-expanding stent, comprising:

  • a distal catheter component having a lumen and comprising;

    a stent support tube; and

    a compound catheter portion tube having a distal end axially connected to a proximal end of the stent support tube and comprising;

    a braided reinforcement, anda helix of wire coaxial with a lumen of the distal catheter component, the helix having a distal end proximal of the stent support tube and a proximal end distal of a proximal end of the compound catheter portion tube;

    a radially compressed stent positioned over the stent support tube such that a distal end of the stent is proximal of a distal end of the support tube;

    a distal sheath surrounding the radially compressed stent;

    a diving sheath having a distal end attached to a proximal end of the distal sheath and radially surrounding the compound catheter portion tube, the distal end of the helix of wire proximal the distal end of the diving sheath;

    a proximal catheter shaft tube having a distal end attached to a proximal end of the distal catheter component;

    a pull wire extending through a lumen of the proximal catheter shaft tube wherein the pull wire is fixedly attached to a proximal section of the diving sheath;

    a proximal sheath having a lumen that contains the proximal catheter shaft tube and an open distal end that receives a proximal end of the distal catheter component; and

    a casing tube surrounding the proximal sheath and having a distal end that receives telescopically the diving sheath;

    whereinthe stent support tube exhibits a support tube diameter,the compound catheter portion tube exhibits a compound catheter portion tube diameter, andthe support tube diameter is equal to the compound catheter portion tube diameter.
