Abstract

This invention is improved systems and methods for effecting lesion formation within human tissue via radio frequency (RF) ablation. An RF generator system (17) is provided which automatically regulates an amount of RF energy delivered to an electrode (43) deployed within area of tissue to be ablated. The RF energy is delivered in such a manner that the temperature of the tissue in the area to be ablated is increased in a controlled manner to a target value over a first selected period of time, and thereafter, maintained at the target value for a second period of time. Maximum lesion formation may be achieved through the use of systems and methods in accordance with the present invention.
