1. An apparatus for electrosurgery, comprising:
- a probe with a distal end and a proximal end, the proximal end forming a handle for holding the probe;
first and second gas delivery channels disposed within probe;
a gas mixing plenum chamber with an inlet and an outlet at the distal end of the probe, the first and second gas delivery channels being in fluid connection with the inlet;
an ignition source proximal to the gas mixing plenum chamber outlet;
a cylindrical sleeve positioned around the distal end of the probe; and
an adjustably positionable actuator disposed on the handle and translatably connected to the cylindrical sleeve, such that the cylindrical sleeve can be longitudinally translated relative to the distal end of the probe, thereby forming a cavity of variable volume about the distal end of the probe.

Abstract
Devices for electrosurgery by means of oxy-hydro combustion and methods for use of such devices in electrosurgical procedures. Provided are devices for combustion of oxygen and hydrogen, or other hydrocarbon fuels, wherein oxygen and hydrogen may be generated by electrolysis or oxygen and hydrogen, or other hydrocarbon fuels, may be supplied, such devices including an ignition source and an adjustable and translatable sheath for controlling such reactions. Also provided is a detachable and positionable sheath for controlling reactions and minimizing tissue damage with conventional electrosurgery devices.

13. A movable sheath adapted for use with a radiofrequency (RF) electrosurgical probe, comprising:
-
a generally cylindrical plenum with an open first end and an open second end and of a diameter such that the open second end may be co-axially placed over the electrode end of an RF electrical probe, whereby the open first end extends beyond the electrode end of the RF electrical probe; and
a flexible polymeric fixation sleeve for securing the position of the generally cylindrical plenum to the RF electrosurgical probe. - View Dependent Claims (14, 15, 16)

17. A apparatus for electrosurgery, comprising:
-
a probe with a distal end and a proximal end;
a concave plenum chamber on the distal end of the probe with an active electrode disposed therein, the active electrode providing for electrolysis of an aqueous medium into hydrogen and oxygen and ignition of such hydrogen and oxygen; and
a circumferential insulated leading edge on the concave plenum chamber on the distal end of the probe for sealing contact with tissue to be treated. - View Dependent Claims (18, 19, 20)
