1. A vascular occlusion coil deployment system for use in placing a coil at a pre-selected site within a vessel comprising:

  • an embolic coil;

    an elongated flexible delivery member having proximal and distal ends;

    a heating element mounted on the distal end of the delivery member;

    a pair of electrical energy conductors attached to said delivery member and being coupled to said heating element; and

    , a heat responsive coupling member attached to both the heating element and to the embolic coil, said heat responsive coupling member exhibits the characteristic of, upon being heated, softening and releasing its bond, whereby upon applying energy through said electrical energy conductors to the heating element, the heating element causes the heat responsive coupling member to release the embolic coil at the pre-selected site.
