1. An apparatus for performing surgical procedures, the apparatus comprising:
- first and second gas delivery channels disposed within an elongated housing having a proximal and distal end;
first and second gas connectors at the proximal end for connecting the first and second gas delivery channels to a first and second gas source;
a gas mixing plenum chamber with an inlet and an outlet at the distal end of the elongated housing, the first and second gas delivery channels being in fluid connection with the inlet; and
an active electrode connected to a current source, the active electrode proximal to the gas mixing plenum chamber outlet.

Abstract
Devices for electrosurgery by means of oxy-hydro combustion. Deleterious effects to tissue are minimized by means of control of acid-base shift reactions, which reactions can further be employed to control oxy-hydro combustion reactions. In one embodiment, radiofrequency energy in electrical connection with electrodes is employed to induce electrolysis in an aqueous salt environment, thereby producing oxygen and hydrogen, with the same energy source employed to initiate a combustion reaction.
