Electrosurgical apparatus including a plurality of electrodes adapted to deliver radio frequency (RF) energy to a tissue and a manipulator in operable connection with the electrodes adapted to move the electrodes. In one embodiment, the electrodes comprise helical electrodes, which may be configured as a pair of bipolar concentric (sharing a common center) or eccentric (off-center) helices, for example. |
