    摘要： A microwave antenna including a feedline, a radiating section, an inflow hypotube, a puck, a transition collar and a sleeve. The feedline includes a coaxial cable including an inner and outer conductor, and a dielectric disposed therebetween. The radiating section includes a dipole antenna coupled to the feedline and a trocar coupled to the distal end of the dipole antenna. The inflow hypotube is disposed around the outer conductor and configured to supply fluid to the radiating portion. The puck includes at least two ribs with inflow slots defined between two adjacent ribs. The transition collar is coupled to the distal end of the inflow hypotube and the first end of the puck. The transition collar includes at least two outflow slots configured to receive fluid from a distal end of the inflow hypotube and to transition the fluid from the outflow slots to a distal end of the radiating section. The sleeve overlays the two outflow slots of the transition collar, the puck and at least the distal portion of the radiating section. The sleeve forms a fluid-tight seal with the transition collar proximal the outflow slots and defines a first gap for transitioning the fluid to exit the outflow slots of the transition collar to the distal end of the radiating section.

    摘要： A microwave applicator for insertion into living body tissue for use in microwave coagulation and ablation treatments includes a microwave transmission line extending between an attachment end of the applicator and an antenna toward an insertion end of the applicator with an outer conductive sleeve forming an enclosed fluid space around the transmission line. A fluid circulation system circulates fluid in the fluid space. A portion of or all of the circulating fluid can be injected into tissue that surrounds the applicator body from approximately the proximal end of a desired heating zone produced by microwave energy radiated from the antenna along the applicator body toward the proximal end of the applicator to hydrate and wet the tissue outside the proximal end of the desired heating zone to reduce the drying of this tissue and limit extension of the heating and ablation zone proximally along the applicator body.

    摘要： An energy-delivery device suitable for delivery of energy to tissue includes an antenna assembly, a chamber defined about the antenna assembly, and a cable having a proximal end suitable for connection to an electrosurgical energy source. The energy-delivery device also includes a flexible, fluid-cooled shaft coupled in fluid communication with the chamber. The flexible, fluid-cooled shaft is configured to contain a length of the cable therein and adapted to remove heat along the length of the cable during delivery of energy to the antenna assembly.

    摘要： A surgical spatula has a planar transmission line (10) for carrying microwave energy formed from a sheet of a first dielectric material (12) which has first (14) and second (16) conductive layers on opposite sides thereof. The surgical spatula also has a coaxial cable (20) for delivering microwave energy to the planar transmission line (10). The coaxial cable has an inner conductor (22), an outer conductor (24) coaxial with the inner conductor (22) and a second dielectric material (26) separating the inner (22) and outer (24) conductors. The inner (22) and outer (24) conductors extend beyond the second dielectric (26) to overlap opposite surfaces of the transmission line (10) and electrically contact the first (14) conductive layer and second (16) conductive layer respectively. The width of the first (14) and second (16) conductive layers is selected to create an impedance match between the transmission line (10) and the coaxial cable (20).
