ABLATION DEVICES WITH ADJUSTABLE RADIATING SECTION LENGTHS, ELECTROSURGICAL SYSTEMS INCLUDING SAME, AND METHODS OF ADJUSTING ABLATION FIELDS USING SAME

摘要

An energy applicator for directing energy to tissue includes a feedline and a radiating section operably coupled to the feedline, wherein the radiating section has a length. The energy applicator also includes a length adjustment member adapted to allow for selective adjustment of the length of the radiating section. The length adjustment member includes a first pivot element and a first tensioning element coupled to the first pivot element.
