Publication number: 20200253660Abstract: 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.Type: ApplicationFiled: October 11, 2019Publication date: August 13, 2020Inventor: Nikolay SUSLOV

Patent number: 8735766Abstract: A cathode assembly and a method for generation of pulsed plasma are disclosed. The cathode assembly comprises a cathode holder connected to multiple longitudinally aligned cathodes, preferably of the same diameter, and different lengths. The method is characterized by forming an electric arc between the cathodes in the assembly and an anode by passing DC current of a predetermined magnitude. Once the arc is established the current is reduced to the magnitude sufficient to sustain an electric arc, or a slightly larger magnitude, thereby reducing the area of arc attachment to a single cathode. Once the area of attachment has been reduced, the current is raised to the operational level of the pulse, while the area of attachment does not increase significantly.Type: GrantFiled: August 6, 2007Date of Patent: May 27, 2014Assignee: Plasma Surgical Investments LimitedInventor: Nikolay Suslov

Patent number: 8613742Abstract: A method for sealing fluid-carrying vessels in a living organism using high temperature plasma is disclosed. A flow rate of 0.25-0.5 L/min of room-temperature plasma generating gas and the initial temperature of the discharged plasma of 12.5-15.5 kK ensure a laminar plasma flow and its ability to penetrate into the vessel. The plasma flow is directed into the vessel, where it keeps a portion of the vessel free of liquid. Heat is transferred to the vessel walls, and the denaturing of collagen in the vessel walls causes the walls to contract until complete occlusion occurs. The method may be used with devices adapted for tissue dissection and coagulation.Type: GrantFiled: January 29, 2010Date of Patent: December 24, 2013Assignee: Plasma Surgical Investments LimitedInventor: Nikolay Suslov

Patent number: 8465487Abstract: The present invention relates to a plasma-generating device comprising an anode, a cathode, and intermediate electrodes. The intermediate electrodes and the anode form an elongate plasma channel that extends from a point between the cathode and the anode and through the anode. The plasma channel has a throttling portion with a throat having the smallest cross-sectional area of the entire plasma channel. As a plasma flow passes through the throttling portion, the plasma flow's speed is increased while its pressure is decreased. By varying the position of the throttling portion in the plasma channel properties of the discharged plasma can be changed. Plasma flows with different properties can be used for various applications, especially, medical procedures.Type: GrantFiled: January 25, 2012Date of Patent: June 18, 2013Assignee: Plasma Surgical Investments LimitedInventor: Nikolay Suslov
