A stimulation lead includes a lead body terminals disposed along the proximal end portion of the lead body electrodes disposed along the distal end portion of the lead body, the electrodes including segmented electrodes. Each of the segmented electrodes includes a base and at least one finned arrangement radially extending from the base. Each of the finned arrangement includes elongated segments, each of the elongated segments extending along at least 50% of a length of a dimension of the base. Each finned arrangement also includes curved segments, where a first curved segment connects a first end portion of a first elongated segment to a first end portion of an intermediate elongated segment and a second curved segment connects a second end portion of a second elongated segment to a second end portion of an intermediate elongated segment. The lead also includes conductors electrically coupling the terminals to the electrodes.
