Abstract

The present invention provides devices and methods for treating tissue. In one embodiment the present invention provides a method of controlling temperature of an applicator body (32), the method comprising providing an applicator body that comprises at least one contact surface (14) A coolant is delivered through at least a portion of the applicator body at a substantially constant rate. Energy is delivered through a heating element (56) so that the contact surface of the applicator body is cooled to a desired temperature.
