Patent ID: 8430874

Claim:
An electrosurgical generator for generating radio frequency (RF) power for supply to an electrosurgical instrument, the generator comprising (i) at least one source of RF output power, (ii) an output stage including at least two output lines adapted to be connected to the electrosurgical instrument, (iii) means for measuring a parameter representative of the condition of the tissue encountered during the electrosurgical procedure, and (iv) a controller operable to control the generator system such that it is capable of delivering one of a first RF waveform to the output lines and a second RF waveform to the output lines, and, in a combined mode, delivering both first and second RF waveforms, the controller being such that, in the combined mode, the controller automatically adjusts a first proportion of an overall signal being the first RF waveform as compared to a second proportion of the overall signal being the second RF waveform in response to the measured parameter representative of the condition of the tissue during the surgical procedure.
