An invasive therapeutic probe assembly and related methods for application of RF energy to a volume of body tissue are provided. The probe assembly includes an RF source configured to provide an RF energy having selected characteristics, a probe having a probe shaft and an antenna positioned therein, and a feed line for providing conductivity from the RF source to the antenna probe. The probe assembly is adapted to generate a zone of therapeutic effectiveness having a selected geometry and volume. The related method includes positioning the probe in a selected location with reference to a target tissue, initiating an electromagnetic field from the antenna having a selected geometry, and producing a zone of therapeutic effectiveness having a selected geometry and volume. The producing step preferably includes, taking periodic temperature measurements from sensors positioned at a selected location, and manipulating the selected characteristics of the RF energy to include duration and/or power level.
