Abstract
An electrosurgical device for devitalizing tissue including a probe body, equipped with at least one electrode, and a cooling device. The probe body is suitable for generating a heat distribution field by means of a high-frequency current for devitalizing the tissue. The cooling device prevents carbonization of the tissue close to the probe body that would normally occur since the maximum current density occurs here. The electrosurgical device is modified such that the heat distribution over the probe body can be adjusted, allowing adjustment or positioning of a maximum cooling zone within the probe body. This regulation may be accomplished by regulating the inlet pressure of the refrigerant supply to the electrosurgical device.
