Claim Text:
1. A device for mapping and ablating tissue, comprising: an elongate body comprising a proximal end and a distal end; a first electrode portion positioned on the elongate body; a second electrode portion positioned adjacent the first electrode portion, the first electrode portion and the second electrode portion being configured to at least partially contact the tissue of a subject and to deliver ablative energy sufficient to at least partially ablate the tissue; at least one electrically insulating gap positioned between the first electrode portion and the second electrode portion, the at least one electrically insulating gap comprising a gap width separating the first and second electrode portions; and wherein the first electrode portion is electrically coupled to the second electrode portion using a filtering element, wherein the filtering element is configured to present a low impedance at a frequency used for delivering the ablative energy via the first and second electrode portions, wherein the frequency used for delivering the ablative energy is within an operating radiofrequency range, and wherein the first and second electrode portions are configured to function like a single electrode within the operating radiofrequency range such that the first and second electrode portions collectively provide the ablative energy to the tissue, and wherein the first and second electrode portions are configured to function as separate electrodes at mapping frequencies that are outside the operating radiofrequency range.
