Abstract
A method and devices for treating a target tissue comprising providing thermal energy to the target tissue and simultaneously providing cryogenic energy to peripheral tissue adjacent or surrounding said target tissue adapted for shielding the peripheral tissue from any adverse effect of the thermal energy. The cooling may be accomplished with a cryogenic arrangement comprising two elements of different electromotive potential conductively connected at a probe junction, and passing an electrical current through the elements to reduce a temperature of the probe junction in accordance with the Peltier effect.
Claims19
An electrode assembly comprising:
- a metallic tip electrode;
- means for delivering current to the metallic tip electrode;
- elements of different electromotive potential conductively connected at a probe junction, wherein said probe junction sounds at least a portion of periphery of the metallic tip electrode;
- and
- means for passing an electrical current through said elements to reduce temperature of said probe junction in accordance with the Peltier effect, wherein the temperature of said probe junction is lower than a temperature of said electrode.
A method for treating a target tissue, the method comprising providing thermal energy to the target tissue and providing cryogenic energy to peripheral tissue adjacent or surrounding said target tissue adapted for shielding the peripheral tissue from an adverse effect of said thermal energy, wherein the cryogenic energy is provided by a probe junction, said probe junction being conductively connected to two elements of different electromotive potential and electrical current being passed through said elements to reduce temperature of said probe junction in accordance with Peltier effect and thereby cool said peripheral tissue.
