Abstract
Apparatus and methods for treating skin conditions that deliver high frequency energy across large tissue areas. The treatment apparatus comprises a treatment tip carrying a plurality of electrodes that are switched such that fewer than all of the electrodes are concurrently energized. The treatment tip includes a cooling mechanism that cools near-surface tissue regions disposed between the skin surface and the treated tissue by cooling the respective electrode that treats each of the regions. The cooling mechanism may include a heat transfer body intervening between the electrodes and a fluid delivery member configured to discharge coolant that impinges the heat transfer body. Alternatively, the cooling mechanism may include a fluid delivery member having individually valve-controlled passages configured to discharge a dedicated stream of coolant at each of the electrodes, a thermoelectric cooler, or a closed-loop fluid delivery member.
