Abstract
An electrode assembly for use with an electrophysiological catheter has a plurality of independently controlled ablation electrodes distributed radially around the electrode assembly. Two ablation electrodes may be positioned in opposition to each other. The electrode assembly may also have microelectrodes for sensing tissue and/or temperature. Methods for using a catheter equipped with such an electrode assembly may include preferentially emitting energy in a radial direction.
