Abstract

A method of applying RF energy includes using an RF energy applicator assembly to apply RF energy to a tissue. The RF energy applicator assembly includes a housing, and RF electrodes coupled to an RF energy source and movably mounted in the housing. The RF electrodes have a retracted position, in which the RF electrodes are retracted inside the housing, and deployed positions in which the RF electrodes protrude out of the housing at different protrusion lengths. An actuator is coupled to the RF electrodes and configured to move the RF electrodes from the retracted position to any one of the deployed positions.
