Abstract: According to one aspect of the present disclosure, a microwave antenna assembly is disclosed. The 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 a proximal portion and a distal portion. The antenna assembly also comprises a sheath disposed over the feedline and the radiating portion defining a chamber around the feedline and the radiating portion. The chamber is adapted to circulate coolant fluid therethrough. The antenna assembly further includes a connection hub having cable connector coupled to the feedline, an inlet fluid port and an outlet fluid port. The connection hub includes a bypass tube configured to provide for flow of the coolant fluid from the cable connector directly to the outlet fluid port.

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.
