    Abstract: A method of performing an ablation procedure includes the steps of inserting an antenna assembly into tissue and supplying energy thereto for application to tissue. The method also includes the step of 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 microwave ablation system includes a generator operable to output energy and an ablation probe coupled to the generator that delivers the energy to a tissue region. The ablation system also includes a controller operable to control the generator and at least one sensor coupled to the ablation probe and the controller that detects an operating parameter of the ablation probe. The controller performs a system check by ramping up an energy output of the generator from a low energy level to a high energy level and monitors an output from the sensor at predetermined intervals of time during the system check to determine an abnormal state. The controller controls the generator to cease the energy output when the controller determines an abnormal state.
