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

摘要

PROBLEM TO BE SOLVED: To provide ablation devices with adjustable radiating section lengths, electrosurgical systems including the same, and methods of adjusting ablation fields using the same.SOLUTION: An energy applicator 100 for directing energy to tissue includes a feedline 110 and a radiating section 150 operably coupled to the feedline and having a length. The energy applicator also includes a length adjustment member 250 adapted to allow selective adjustment of the length of the radiating section.SELECTED DRAWING: Figure 1
