Abstract
A method of heating a tract organ of the living body with high-frequency electric current, includes the step of controlling a flow volume of a coolant supplied into a first electrode so as to be substantially equal to that of a blood which flows in a living body tissue at a portion where the first electrode is disposed while controlling a temperature of the coolant to a temperature range of the living body tissue at the portion, the coolant being an aqueous solution of salts at a predetermined concentration. The method makes it possible to effect safely a hyperthermic treatment. An apparatus for carrying out the method is also disclosed.
