1. An electrosurgical system including a generator (10) for generating radio frequency power, an electrosurgical instrument (12) including at least first and second electrodes (3A, 3B) carried on the instrument, the first and second electrodes (3A, 3B) being shaped so as to contact tissue without penetrating it, and a monopolar patient return electrode (11) separate from the instrument,the generator (10) comprising at least one source (1) of radio frequency (RF) power, and having a first supply state in which an RF waveform is supplied between the first electrode (3A) of the electrosurgical instrument (12) and the monopolar return electrode (11), and a second supply state in which an RF waveform is supplied between the second electrode (3B) and the monopolar return electrode (11), and feeding means operable such that, in at least one mode of the generator, the feeding means is adapted to alternate between the first and second supply states.
