    摘要: A microwave antenna assembly (12, 112) comprises a feedline (20, 120) including an inner conductor (50, 150), an outer conductor (56, 156) and an inner insulator (52, 152) disposed therebetween, a radiating portion and a connection hub. The radiating portion (18, 118) includes a dipole antenna (40, 140) having a proximal (42, 142) and distal (44, 144) portions. The proximal portion includes at least a portion of the inner conductor (50, 150) and the inner insulator (52, 152) and the distal portion (44, 144) includes a conductive member (45, 145). The connection hub (22, 122) includes a cable connector (79) coupled to the feedline, inlet (32) and outlet(30) fluid ports. A tip (48) having an insertion base is coupled to the distal end of the antenna. A sheath (38) is fluidly coupled to the connection hub (32) and the tip and defines a chamber (89) around the feedline (20, 120) and the radiating portion (18, 118), the chamber being adapted to circulate dielectric coolant fluid therethrough from the inlet fluid port to the outlet fluid port.

    摘要: A device for directing energy to a target volume of tissue includes an inner conductor having a length and an outer conductor coaxially surrounding the inner conductor along the length. The outer conductor has a proximal portion and a distal portion. The distal portion of the outer conductor is provided with a number of apertures N defined therein for radiating energy, where N is an integer greater than 1, each aperture having a size and extending at an angle relative to a longitudinal axis of the outer conductor. At least one of the size and the angle of each aperture is varied in relation to the other apertures N-1 such that the energy radiated along the distal portion is substantially uniform.
