Abstract
An ablation device includes an electrode having an enclosed lumen, and a heat sink located within the lumen. An ablation device includes an elongated body, an electrode secured to the elongated body, and a heat sink connected to the electrode, wherein the heat sink is confined by the electrode and at least a portion of the elongated body. An ablation device includes an electrode, and a heat sink connected to the electrode, wherein the heat sink is not connected to a pump.
Claims4
An ablation device comprising:
- an elongated body having a proximal end and a distal end and a lumen extending at least partially from the proximal end to the distal end;
- an electrode disposed at the distal end of the elongated body, the electrode having a lumen in communication with the lumen of the elongated body;
- a wall disposed in one of the lumen of the elongated body and the lumen of the electrode, the wall including an opening therein;
- a tube coupled to the opening in the wall;
- and
- a liquid heat sink confined by the wall and an inner surface of the electrode wherein the opening in the wall allows liquid heat sink to flow there through and into the tube, the liquid heat sink having a boiling point such that upon energizing the electrode the heat sink maintains its liquid state.
