    摘要： 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.

    摘要： A microwave antenna assembly is disclosed. The microwave antenna assembly includes a feedline having an inner conductor, an outer conductor and an inner insulator disposed therebetween and a radiating portion including a dipole antenna having an operative length and an inductor. The inductor is adapted to adjust the operative length of the dipole antenna based on the frequency of the microwave energy supplied to the dipole antenna.

    摘要： A microwave ablation system for treating tissue includes an assembly of antennas adapted to connect to a microwave generator. The microwave generator generates microwave energy. Each antenna of the assembly of antennas includes inner and outer conductors. The inner conductor has a length. The outer conductor has a longitudinal axis defined along a length thereof. The outer conductor at least partially surrounding the inner conductor at least partially along the length thereof. One of the inner conductor and the outer conductor is movable with respect to the other. At least one antenna of the assembly of antennas is deployable from a first state for ablating a first ablation region of tissue to a second deployable state for ablating a second ablation region of tissue. The first and second ablation tissue regions overlap to define an aggregate ablation region.
