摘要： 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.

摘要： A device for directing energy to a target volume of tissue includes an inner conductor having a length and an outer conductor coaxially surrounding the inner conductor along the length. The outer conductor has a proximal portion and a distal portion. The distal portion of the outer conductor is provided with a number of apertures N defined therein for radiating energy, where N is an integer greater than 1, each aperture having a size and extending at an angle relative to a longitudinal axis of the outer conductor. At least one of the size and the angle of each aperture is varied in relation to the other apertures N−1 such that the energy radiated along the distal portion is substantially uniform.
