Abstract
An electrode structure for a distal tip of an electrosurgical instrument that enables efficient delivery of radiofrequency (RF) energy in a forward (distal) direction and uniform delivery of microwave energy for ablation in a region surrounding the distal tip. The instrument comprises a tip body having a first electrode and a second electrode, where the second electrode is spaced from the first electrode exposed dielectric material. The first electrode is connected through the tip body to an inner conductor of a coaxial feed. The second electrode is electrically connected to the outer conductor of the coaxial feed by a field-shaping conductive structure formed in or on the tip body. The field-shaping conductive structure is configured to shape a radiation profile of microwave energy emitted from the tip body.
