Abstract: A method of manufacturing a microwave ablation device, the method including applying a balun short circumferentially about an outer conductor of a coaxial feedline and applying a dielectric material circumferentially about the outer conductor of the coaxial feedline and in contact with the balun short to form a balun. The method further including extending a temperature sensor along the coaxial feedline such that the sensor contacts the balun short, securing the temperature sensor to the coaxial feedline with a first heat shrink material, and securing the dielectric material, balun short, and temperature sensor in contact with each other and to the coaxial feedline using a second heat shrink material.

Abstract: A microwave ablation system incorporates a microwave thermometer that couples to a microwave transmission network connecting a microwave generator to a microwave applicator to measure noise temperature. The noise temperature is processed to separate out components the noise temperature including the noise temperature of the tissue being treated and the noise temperature of the microwave transmission network. The noise temperature may be measured by a radiometer while the microwave generator is generating the microwave signal or during a period when the microwave signal is turned off. The microwave ablation system may be configured as a modular system having one or more thermometry network modules that are connectable between a microwave applicator and a microwave generator. Alternatively, the modular system includes a microwave generator, a microwave applicator, and a microwave cable that incorporate a microwave thermometry network module.
