  • Patent number: 5669907
    Abstract: A surgical system has a multiple electrode electrosurgical capability in combination with a gas plasma capability for delivery of electrosurgical energy to the tissue or bodily fluids of a patient. The system includes a holder, a source of electrical energy, electrodes connected to the source of electrical energy, one or more passages carried on the holder for transporting ionizable gas, and a source of ionizable gas of a selectable flow rate. The gas passages may include at least one electrode extending toward the operative site. The gas passages may include a part that creates a vortex in the gas flow. The electrodes may be coaxially placed in the gas passages. The system may also be configured such that two electrodes are each shrouded by the ionized gas so that the electrosurgical energy is conducted to the tissue or bodily fluids of the operative site by passing along conductive pathways in the ionized gas from each electrode. There may also be a dielectric barrier between the conductive pathways.
