  • Patent number: 10758303
    Abstract: An ablation apparatus places electrodes at the perimeter of a cavity. In an embodiment, the alternating electric field is used to expose the cavity to enough energy to ablate the cavity. In an embodiment, two modes are used to expose different regions of the cavity to different amounts of power for so that the thermal effect is more uniform. In an embodiment, the electrodes have a relatively large surface area so as to avoid charring the cavity, but are shaped so as to fit within a body orifice. For example, the diameter of the sheathed housing the electrodes during penetration may be only 5.5 mm.

  • Patent number: 10631911
    Abstract: Volumetrically oscillating plasma flows, the volume of which controllably expands and contracts with time, are disclosed. Volumetrically oscillating plasma flows are generated by providing an energy with a power density that changes with time to the plasma-generating gas to form a plasma flow. The changes in the energy power density result in plasma flow volumetric oscillations. Volumetric oscillations with a frequency of above 20,000 Hz results in ultrasonic acoustic waves, which are known to be beneficial for various medical applications. System for providing volumetrically oscillating plasma flows and a variety of surgical non-surgical applications of such flows are also disclosed.
