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.
