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.

Claims (4)

1. 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 wherein the active electrode comprises a gas porous structure.
