Abstract:
A vascular occlusion coil deployment system for use in placing a coil at a pre-selected site within a vessel comprising:an elongated flexible positioning member having a lumen extending therethrough and having proximal and distal ends;an embolic coil;an elongated flexible delivery member having a lumen extending therethrough and being positioned within the lumen of the positioning member and having proximal and distal ends;a heating element mounted on the distal end of the delivery member;an energy transmission conductor extending through the lumen of the delivery member and extending from the proximal end to the distal end of the delivery member wherein said energy transmission conductor is an electrical conductor, said energy transmission conductor being coupled to said heating element; and,a heat responsive coupling member adhesively bonded to both the heating element and to the embolic coil, said heat responsive coupling member exhibits the characteristic of, upon being heated, releasing its adhesive bond whereby upon applying energy through the energy transmission conductor to the heating element, the heating element causes the heat responsive coupling member to release the embolic coil at the pre-selected site.
