2 results about "Monopolar electrosurgery" patented technology

This application relates to independent control of dual RF monopolar electrosurgery with shared return electrode. More specifically, an electrosurgical generator is disclosed that includes a first radio frequency source having a first power supply configured to output a first direct current waveform, a first radio frequency inverter coupled to the first power supply and configured to generate a first radio frequency waveform from the first direct current waveform, and a first controller configured to control the first radio frequency inverter. The electrosurgical generator also includes a second radio frequency source having a second power supply configured to output a second direct current waveform, a second radio frequency inverter coupled to the second power supply and configured to generate a second radio frequency waveform concurrently with the generation of the first radio frequency waveform, and a second controller configured to control the second radio frequency inverter.
