    摘要: A coupler for coupling a flexible coaxial cable (32), a fluid cooling system (40) and the outer sheath (35) of a catheter (30), the coupler comprising:
    a fluid coupler body (845a) including:
    a fluid inlet (842a) configured to operably couple to a source of cooling fluid and receive fluid therefrom;
    a fluid outlet (843a) configured to operably couple to a fluid discharge; and
    an outer sheath coupler (845b) forming an aperture for coupling with an outer sheath (35) of a catheter while forming a fluid-tight seal therewith; and

    a fluid sealing system (819) housed in the fluid coupler body including:
    a distal sealing diaphragm (819a) configured to form a fluid-tight seal about an outer surface of an inflow lumen (842) and a fluid-tight seal with an interior surface of the fluid coupler body (845a) defining an outflow plenum (843b) in fluid communication with the fluid outlet (843a); and
    a proximal sealing diaphragm (819b) configured to form a fluid-tight seal about an outer surface of the coaxial cable (32) and a fluid-tight seal with an interior surface of the fluid coupler body(845a) thereby forming an inflow plenum (842b) in fluid communication with the fluid inlet (842a).

    摘要: A microwave antenna comprises a feedline (20) including a coaxial cable and a radiating section (18) coupled to the feedline. The radiating section includes a choke (19) .An inflow tube (55) is disposed around an outer conductor of the coaxial cable. The inflow tube defines an inlet flow path configured to supply a coolant fluid to the radiating section. A transition collar (53) forms a portion of the choke. The collar is of a dielectric material and has a proximal end and a distal end. The proximal end is coupled to a distal end of the inflow tube. The transition collar further includes at least one outflow aperture (53a) at the proximal end thereof configured to receive the fluid from the distal end of the inflow tube and transition the fluid from the at least one outflow slot to a distal end of the radiating section.
