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 for cooling a medical device includes fluidly connecting a cooling fluid reservoir to a medical device. The fluid connection includes a fluid out-flow path and a fluid return path corresponding to the fluid reservoir. The cooling fluid is pumped from the fluid reservoir to the medical device. The medical device is energized and the heat generated by the energization is absorbed by the cooling fluid pumped to the medical device. The cooling fluid is received at the reservoir containing the absorbed heat. The cooling fluid transfers the absorbed heat to the cooling fluid in the reservoir and to the environment adjacent to the reservoir.
