Abstract
A electrosurgical generator and system includes a first radio frequency (RF) source and a second RF source, a first controller configured to output a first control signal to the first RF source to generate a first RF waveform, and a second controller configured to output a second control signal to the second RF source to generate a second RF waveform. The electrosurgical generator further includes a first output port and a second output port configured to provide the respective first RF waveform and the second RF waveform for treatment of tissue.

An electrosurgical generator, comprising:
- a first radio frequency (RF) source and a second RF source;
- a first controller configured to output a first control signal to the first RF source to generate a first RF waveform;
- a second controller configured to output a second control signal to the second RF source to generate a second RF waveform, with the first RF source and the second RF source configured to simultaneously generate the respective first RF waveform and second RF waveform;
- and
- a first output port and a second output port configured to provide the respective first RF waveform and the second RF waveform for treatment of tissue.
An electrosurgical system, comprising:
- an electrosurgical generator, comprising:
- a first radio frequency (RF) source and a second RF source;
- a first controller configured to output a first control signal to the first RF source to generate a first RF waveform;
- a second controller configured to output a second control signal to the second RF source to generate a second RF waveform;
- and
- a first output port and a second output port configured to provide the respective first RF waveform and the second RF waveform;
- a first electrosurgical instrument coupled to the first output port for delivering electrosurgical energy based on the first RF waveform;
- and
- a second electrosurgical instrument coupled to the second output port for delivering electrosurgical energy based on the second RF waveform;
- wherein the electrosurgical generator is configured to simultaneously provide the first RF waveform and the second RF waveform to the respective first electrosurgical instrument and the second electrosurgical instrument.
