Rf power time multiplex strategy to deliver two independent bvn therapies simultaneously from single power source

A tissue ablation system, comprising:

• a radiofrequency generator having a power source and a controller operatively coupled to the power source and having a processor and a memory element;
• a first radiofrequency probe having at least one electrode and electrically coupled to the radiofrequency generator to form a first channel;
• a second radiofrequency probe having at least one electrode and electrically coupled to the radiofrequency generator to form a second channel;
• wherein the power source is configured to deliver radiofrequency power to the electrodes of the first and second radiofrequency probes sufficient to provide controlled heating of tissue surrounding the electrodes during a surgical procedure;
• wherein the processor is configured to execute program instructions to:
• determine a first power demand for the first channel and a second power demand for the second channel;
• implement a power-time multiplexing technique by:
• allocating a first duty cycle to the first channel and a second duty cycle to the second channel;
• and
• determining a common radiofrequency voltage for each of the first channel and the second channel during the first and second duty cycles, respectively, based on whichever of the first power demand or the second power demand has a higher radiofrequency voltage;
• and
• deliver radiofrequency power at the common radiofrequency voltage between the first channel and the second channel within each of the first and second duty cycles, respectively, when each of the first and second channels is in an activation state.
