Patent
Electrosurgical generator and system
TL;DR: In this article, the authors present a controller that can cause the generator to supply a blended output signal alternating constantly between a first output signal across the output connections in which the radio frequency output voltage developed across output connections is limited to at least a first predetermined threshold value for cutting or vaporization of tissue, and a second output signal with a power supply coupled to the output stage for supplying power to output stage.

Electrosurgical method and apparatus for initiating an electrical discharge in an inert gas flow
TL;DR: An electrosurgical method and apparatus for coagulating by fulguration where the electrical discharge is established through a formation of flowing inert gas where the formation may either be a diffuse blanket of the flowing gas or a well defined column thereof is described in this paper.
Patent
Electrosurgical conductive gas stream technique of achieving improved eschar for coagulation
TL;DR: In this paper, electrical radio frequency energy is conducted to the tissue in ionized conductive pathways in the gas jet in order to achieve coagulation and to expose the tissue stroma.
Patent
Method and apparatus for generating plasma
TL;DR: In this paper, a hollow, electrically-conductive conduit connected in series with a radio frequency resonant circuit is constructed for producing an electric-field plasma, which is generated at ambient pressures and at substantial thermal nonequilibrium.
Patent
Electrosurgical conductive gas stream equipment
TL;DR: An electrosurgical unit for conducting a predetermined ionizable gas in a jet stream to the tissue at a predetermined flow rate sufficient to clear natural fluids from the tissue and to substantially expose the tissue stroma and for exposing the gas to an electrical radio frequency energy to ionize the gas in conductive pathways in the gas jet stream as mentioned in this paper.
