Abstract
An electrosurgical instrument for delivering both microwave and radiofrequency (RF) energy in which a pair of longitudinally spaced electrodes are combined with an intermediate tuning element to enable both effective bipolar RF ablation and/or coagulation and microwave ablation with a field shape that is constrained around the instrument tip. The instrument comprises a radiating tip disposed at a distal end of a coaxial cable. The tip has a distal electrode and a proximal electrode disposed on a surface of a dielectric body and physically separated by an intermediate portion of the dielectric body. A tuning element is mounted in the intermediate portion.
