Abstract

Electrode assemblies include segmented electrodes disposed on a catheter. The segmented electrodes can be constructed at the tip of the catheter. Tip electrodes can be constructed from an electrically insulative substrate comprising an inner lumen, an external tip surface, and a plurality of channels extending from the inner lumen to the external tip surface, a plurality of segmented electrodes, and a plurality of spot electrodes. Each of the plurality of segmented electrodes and each of the plurality of spot electrodes can be laterally separated from each other by an electrically non-conductive substrate portion and each of the spot electrodes and each of the segmented electrodes can be electrically coupled to at least one wire or conductor trace.
