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.

10. An electrosurgical apparatus comprising:
-
a housing having proximal and distal ends;
an active electrode disposed adjacent the distal end of the housing, the electrode comprising an alloy that induces release of hydrogen; and
an electrical connector extending from the active electrode to the proximal end of the housing for connecting the electrode to a source of current. - View Dependent Claims (11, 12)

13. An electrosurgical apparatus comprising:
-
an elongated lumen having proximal and distal ends;
an active electrode adjustably positionable within and along the long axis of the lumen; and
an electrical connector extending from the active electrode connecting the electrode to a source of current. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. An apparatus for electrosurgery, comprising
an active electrode; -
a return electrode fixed in position relative to the active electrode; and
a radiofrequency power supply in electrical connection with the active electrode and return electrode, the power supply generating less radiofrequency power than that required to induce plasma ionization;
whereby on immersion of the active electrode and return electrode in an aqueous salt ion environment, the application of radiofrequency power induces electrolysis of a portion of the aqueous salt ion environment thereby producing hydrogen and oxygen and further initiates a hydrogen and oxygen combustion reaction.
