Device and method for producing high-concentration, low-temperature nitric oxide

A device for forming NO-containing plasma gas flow to treat a biological object, the device comprising:

• an anode,
• a cathode, and
• an insulator surrounding the cathode, the cathode including a plurality of tangentially arranged holes for creating a vortex of fluid flow as the fluid exits the cathode;
• a cathode insulator disposed about the insulator;
• a bushing coupled to the cathode insulator;
• an interelectrode area between the cathode and the anode;
• an interim electrode disposed about a proximal end of the cathode;
• an interim electrode standoff coupled between the insulator and the interim electrode;
• a chamber standoff coupled between the interim electrode and the anode;
• and
• an NO-containing gas flow outlet channel leading from the interelectrode area to a nozzle for directing the NO-containing gas flow from the device;
• wherein at least one of the insulator, cathode insulator, interim electrode standoff, and chamber standoff are made from a dielectric material.
