ABSTRACT:
An ablation catheter for ablating tissue, such as endocardial tissue. The ablation catheter includes a foam tip with an electrode embedded therein. Conductive fluid, such as saline solution, is pumped through the foam tip out to the tissue adjacent to the foam tip. The conductive fluid electrically couples the electrode embedded in the foam tip with the tissue to be ablated in order to effect ablation. The flow of the conductive fluid and the foam tip both help prevent any combustible products of the ablation from reaching the high current surfaces of the electrode itself.
