Abstract: An electrosurgical system includes an energy applicator adapted to direct energy to tissue, an electrosurgical power generating source, and a surface-contact detection device. The surface-contact detection device is operably associated with the energy applicator. The surface-contact detection device is communicatively-coupled to the electrosurgical power generating source. The surface-contact detection device includes at least one optical transmitter to generate optical signals, a lens member configured to reflect optical signals generated by the optical transmitter when the lens member is disposed in contact with tissue, and at least one optical receiver to receive optical signals reflected by the lens member. The electrosurgical power generating source is adapted to transmit energy to the energy applicator when it is determined that the lens member is disposed in contact with tissue.

The proximal end is configured to couple to a source of electrosurgical energy via first and second channels extending along a length of the housing to the distal end thereof. The distal end includes a reflector having a dielectric load operably coupled thereto and configured to receive at least a portion of the first conductor therein. In a first mode of operation, electrosurgical energy is transmitted to the first channel and reflected from the reflector to electrosurgically treat tissue.

Abstract: Disclosed is a system and method for enabling user preview and control of the size and shape of an electromagnetic energy field used in a surgical procedure. The disclosed system includes a selectively activatable source of microwave surgical energy in the range of about 900 mHz to about 5 gHz in operable communication with a graphical user interface and a database. The database is populated with data corresponding to the various surgical probes, such as microwave ablation antenna probes, that may include a probe identifier, the probe diameter, operational frequency of the probe, ablation length of the probe, ablation diameter of the probe, a temporal coefficient, a shape metric, and the like. The probe data is graphically presented on the graphical user interface where the surgeon may interactively view and select an appropriate surgical probe. Three-dimensional views of the probe(s) may be presented allowing the surgeon to interactively rotate the displayed image.
