Abstract:
1. An energy applicator for directing energy to tissue, comprising: a feedline; a radiating section operably coupled to the feedline, the radiating section including a dielectric material and an inner conductor, a portion of the inner conductor extending distally beyond a distal end of the dielectric material, wherein the radiating section has a length; and a length adjustment member adapted to allow for selective adjustment of the length of the radiating section, wherein the length adjustment member includes a tapered portion disposed at a distal end of the radiating section, the tapered portion defining a cavity therein, wherein a distal portion of the portion of the inner conductor extending distally beyond the distal end of the dielectric material includes a coiled portion disposed within the cavity, the cavity configured to allow the coiled portion of the inner conductor to wind or unwind as the length of the radiating section is adjusted.
