Treatment apparatus and methods for delivering high frequency energy across large tissue areas

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