Abstract

This invention is an electrode catheter for cardiac electrophysiology. An elongated body (11) suitable for intravascular insertion surrounds a plurality of electrode lead wires (19). A
composite electrode comprises a plurality of tip electrodes (31) and defines a margin (40) along a proximal edge.
Each tip electrode (31) is electrically connected to an associated electrode lead wire (19) and is adjacent to another tip electrode (31) on at least one side along an axis of the elongated body (11). Each tip electrode (31) is separated from another tip electrode (31) by insulation (32).
A cup electrode (33) is electrically connected to an associated electrode lead wire (19) and defines a cavity (50) shaped to overlap the margin (40) of the composite electrode (30). The cup electrode (33) is fixedly secured to the composite electrode (30) and to a distal end of the elongated body (11) and is separated from the composite electrode (30) by insulation (32).
