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

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

• forming an NO-containing gas flow in an interelectrode area of a device, wherein the device comprises:
• an anode,
• a cathode, and
• an insulator surrounding the cathode, the cathode including a plurality of tangentially arranged holes for creating a vortex of a fluid flow as the fluid exits the cathode;
• a cathode insulator disposed about the insulator;
• the 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;
• and
• a chamber standoff coupled between the interim electrode and the anode;
• directing the NO-containing gas flow from the device via a flow outlet channel leading from the interelectrode area;
• and
• directing the NO-containing gas flow from the nozzle toward the biological object to treat the biological object.
