Electrosurgical system
First Claim
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.

Abstract
An electrosurgical system includes a generator for generating radio frequency power, an electrosurgical instrument including at least first and second electrodes carried on the instrument, and a monopolar patient return electrode separate from the instrument. The generator comprises at least one source of radio frequency (RF) power, and has a first supply state in which the RF waveform is supplied between the first electrode and the patient return electrode, and a second supply state in which the RF waveform is supplied between a second electrode and the monopolar patient return electrode. A controller is operable to control the generator such that, in at least one mode of the generator, feeding means within the generator is adapted to alternate between the first and second supply states.

12. An electrosurgical system including a generator (10) for generating radio frequency (RF) power, an electrosurgical instrument (12) including at least first and second tissue surface treatment electrodes (3A, 3B) carried on the instrument and each shaped to apply an electrosurgical RF voltage to a tissue surface position, and a monopolar patient return electrode (11) separate from the instrument for application to a different part of the patient'"'"'s body,
the generator (10) comprising at least one source (1) of RF power and first, second and third output connections coupled to the first second and return electrodes respectively, and having a first supply state in which an RF waveform is supplied via the first and third output connections between a first electrode (3A) of the electrosurgical instrument and the monopolar return electrode (11), and a second supply state in which an RF waveform is supplied via the second and third output connections between the second electrode (3B) and the monopolar patient 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.
