ABSTRACT:
An electrode catheter for cardiac electrophysiology. An elongated body suitable for intravascular insertion surrounds a plurality of electrode lead wires. A composite electrode comprises a plurality of tip electrodes and defines a margin along a proximal edge. Each tip electrode is electrically connected to an associated electrode lead wire and is adjacent to another tip electrode on at least one side along an axis of the elongated body. Each tip electrode is separated from the another tip electrode by insulation. A cup electrode is electrically connected to an associated electrode lead wire and defines a cavity shaped to overlap the margin of the composite electrode. The cup electrode is fixedly secured to the composite electrode and to a distal end of the elongated body and is separated from the composite electrode by insulation.
