Abstract: An energy applicator for directing energy to tissue includes a feedline having an inner conductor, an outer conductor and a dielectric material disposed therebetween, and an antenna assembly having a radiating section operably coupled to the feedline. The energy applicator also includes a first balun structure configured to substantially confine energy to the radiating section when the energy applicator is energized and disposed in tissue, and a second balun structure configured to substantially prevent energy emitted from the radiating section from propagating proximal to the second balun structure along the feedline when the energy applicator is energized but not disposed in tissue.

Abstract: A method of treating tissue includes positioning a probe in proximity to tissue, reducing a temperature of the tissue such that a temperature of a portion of the tissue that is closer to the probe is less than a temperature of a portion of the tissue that is farther from the probe, and raising a temperature of the tissue such that the temperature of the portion of the tissue that is closer to the probe increases at a faster rate than the temperature of the portion of the tissue farther from the probe.
