Abstract
Devices and methods for electrolytic electrosurgery wherein a detector is located proximal to an active electrode on an electrosurgical probe, optionally disposed between the active electrode and a return electrode, the detector detecting at least on parameter relating to electrolysis. The detected parameter can include pH concentration, temperature, conductivity, impedance, ion, concentration, electrolytic gas consumption, electrolytic gas production, pressure or sound. The detected parameter can be employed in control systems to control systems to control activation or operation of the electrosurgical probe.

65. An apparatus for electrosurgery, comprising:
-
a probe with a distal end and a proximal end, with at least one active electrode and at least one return electrode disposed on the distal end, the proximal end forming a handle for holding the probe;
a cylindrical insulating sleeve positioned around the distal end of the probe;
an adjustably positionable actuator disposed on the handle and translatably connected to the cylindrical insulating sleeve, such that the cylindrical insulating 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; and
at least one detector proximal on the distal end of the probe and within the cavity of variable volume for detecting a parameter relating to electrolysis or oxy-hydro combustion. - View Dependent Claims (66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93)
