Abstract
An embolic coil deployment system for placing a coil at a preselected site within a vessel of the human body. The deployment system includes a heating element at the distal end of a delivery member and a heat responsive coupling for holding the coil during positioning of the coil and activation means for releasing the coil at a desired position within the vessel.
Claims4
A vascular occlusion coil deployment system for use in placing a coil at a preselected 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, said energy transmission conductor being coupled to said heating element;
- and,
- a non-metallic heat responsive coupling member coupled to the heating element and normally retaining the embolic coil, said heat responsive coupling member exhibits the characteristic of, upon being heated, releasing the embolic coil at the preselected site.
