1. A radio frequency tissue ablation system comprising a radio frequency generator, the generator comprising:
- a radio frequency source,at least four independently controllable radio frequency outputs,a user interface, anda controller configured to deliver radio frequency energy from the radio frequency source to the at least four radio frequency outputs in at least one of monopolar mode, bipolar mode, and combination of monopolar and bipolar modes in response to a configuration selection made through the user interface, wherein the controller is further configured to adjust a voltage phase angle of of the at least four radio frequency outputs in response to a configuration selection made through the user interface in order to adjust at least one of the magnitude of power delivered and the ratio of monopolar to bipolar power delivery.
