Patent ID: 8394092

Claim:
An electrosurgical system for directing energy to tissue, comprising: a generator assembly operable to supply power having a selected phase, amplitude and frequency; and an applicator array assembly including: a shell assembly; a plurality of energy applicators disposed within the shell assembly, each one of the plurality of energy applicators including: a length of coaxial cable having an inner conductor, an outer conductor coaxially disposed around the inner conductor, and a dielectric material disposed therebetween; an elongated electrically-conductive member longitudinally disposed at a distal end of the inner conductor; a balun structure disposed on the outer conductor; an electrically-conductive cylinder coaxially disposed around a distal portion of the balun structure; and a dielectric structure disposed substantially adjacent to a distal end of the electrically-conductive cylinder, wherein the dielectric structure longitudinally extends from the distal end of the electrically-conductive cylinder to a distal end of the electrically-conductive member; and a power divider unit electrically coupled to the generator assembly, the power divider unit operable to divide power into the applicator array assembly.
