摘要： An ablation device includes an antenna assembly having a radiating portion configured to deliver energy from a power source to tissue of a patient. The radiating portion has an outer conductor and an inner conductor extending therethrough. The inner conductor is disposed within the outer conductor and defines a longitudinal axis. One of the inner conductor and the outer conductor is movable relative to the other to cause at least a portion of the outer conductor to expand radially relative to the longitudinal axis.

摘要： A tissue sensor probe and corresponding electromagnetic surgical ablation system are disclosed. The system includes an ablation probe operatively coupled to a generator, a controller operatively coupled to the generator, and a tissue sensor probe operatively coupled to the controller. The tissue sensor probe includes an electrically-conductive enclosure configured to shield a temperature sensor from electromagnetic radiation produced by the ablation probe. At least a portion of the electrically-conductive enclosure is made of a high thermal-conductivity material. A material of high thermal-conductivity is disposed in the electrically-conductive enclosure in thermal association with the thermally-conductive material of the electrically-conductive enclosure. The temperature sensor is disposed in the material of high thermal conductivity so as to electrically isolate the temperature sensor from the enclosure. The temperature sensor provides tissue temperature to the controller, which monitors tissue temperature to determine tissue status and to activate and deactivate the generator based on the tissue status.

摘要： A method of performing an ablation procedure includes the initial step of supplying a fluid to a cooling chamber defined within an antenna assembly. The method also includes the steps of decreasing the temperature of the fluid to form a solid material and inserting the antenna assembly into tissue. The method also includes the step of supplying energy to the antenna assembly to treat tissue. Residual heat from the antenna assembly transitions the solid material back to the fluid. The method also includes the step of circulating the fluid within the antenna assembly to dissipate heat emanating from the antenna assembly.
