1. A renal nerve modulation catheter, comprising:
- an elongate catheter shaft;
wherein the elongate catheter shaft has a plurality of cuts formed therein that define a plurality of electrode assemblies;
wherein each of the plurality of electrode assemblies includes a main strut that branches into one or more branched spacer struts extending from the main strut and extending radially outward when in an expanded configuration, the main strut including flanking strut regions on either side of an electrode extending from the main strut and disposed between the flanking strut regions, the electrode extending radially inward in a direction opposite from the one or more branched spacer struts.
