Devices, systems and methods for enhancing physiological effectiveness of medical cold plasma discharges

An electrosurgical apparatus comprising:

• a first fluid flow housing including a proximal end, a distal end, a gas port, and a hollow interior, the gas port configured to provide a first gas to the hollow interior, such that, the first gas flows through the hollow interior and is provided to the distal end of the first fluid flow housing, the hollow interior having a first diameter;
• a nozzle including a proximal end and a distal end, the proximal end of the nozzle coupled to the distal end of the first fluid flow housing, the nozzle further including a hollow interior and at least one secondary gas input disposed through an exterior portion of the nozzle and providing access to the hollow interior of the nozzle, the hollow interior including a throttle portion having a second diameter, the second diameter being smaller than the first diameter;
• and
• an electrode disposed through the hollow interior of the first fluid flow housing, the electrode including a distal tip and configured to receive electrosurgical energy from an electrosurgical generator, such that, when the first gas passes over the distal tip of the electrode and the electrode receives electrosurgical energy, the first gas is at least partially ionized to generate a plasma discharge beam, the plasma discharge beam exiting the distal end of the first fluid flow housing;
• wherein a pressure difference between the hollow interior of the nozzle and the exterior of the nozzle causes a second gas to be drawn into the hollow interior of the nozzle through the at least one secondary gas input and injected into the plasma discharge beam.
