    Abstract: A method of performing an ablation procedure includes inserting an antenna assembly into tissue and supplying energy thereto for application to tissue. The method also includes causing contact between a first material and at least one other material disposed within the antenna assembly to thermally regulate the antenna assembly. According to another embodiment, an ablation system includes an energy delivery assembly. A first chamber is defined within the energy delivery assembly and is configured to hold a first chemical. Another chamber is defined within the energy delivery assembly and is configured to hold at least one other chemical. The first chamber and the other chamber are configured to selectively and fluidly communicate with each other to cause contact between the first chemical and the at least one other chemical to cause an endothermic reaction and/or an exothermic reaction.

    Abstract: A system for determining probability of tissue damage includes a plurality of return electrodes adhered to a patient and adapted to couple to an electrosurgical generator configured to generate an electrosurgical current. The system also includes a current monitor and a switching component connected in series with each of the plurality of the return electrodes. The current monitor is configured to measure the electrosurgical current passing therethrough. The system further includes a processor coupled to each of the current monitors and the switching components. The processor is configured to determine the balance of a current load among the plurality of the return electrodes and configured to control each of the switching components to adjust the current passing through each of the return electrodes to balance the current load.

    Abstract: A system and method for supplying microwave energy to tissue for microwave therapy includes an electrosurgical generator having an output for coupling to a surgical instrument. The electrosurgical generator includes a microwave energy source and a controller for controlling the operation of the electrosurgical generator. The surgical instrument, coupled to the electrosurgical generator, includes a microwave antenna for delivering microwave energy from the microwave energy source. The controller of the electrosurgical generator is operable for causing the electrosurgical generator to apply at least two pulses of microwave energy.

    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.
