Claims (44)

1 . An energy transmission applicator comprising:

a disposable interface at a distal end of said applicator, said disposable interface comprising a disposable engagement mechanism;

an antenna structure including at least one antenna aperture arranged to transmit energy through said distal end of said applicator; and

a cooling circuit including a cooling plate, wherein at least a portion of said cooling circuit is positioned between said antenna and said distal end of said applicator.

2 . An energy transmission applicator according to claim 1 wherein said antenna comprises:

a plurality of antennas;

a distribution element arranged to transmit said energy to said plurality of antennas.

3 . An energy transmission applicator according to claim 2 wherein said distribution element comprises a microwave switch.

4 . An energy transmission applicator according to claim 2 wherein said distribution element comprises a power splitter.

5 . An energy transmission applicator according to claim 1 wherein said energy transmission applicator further comprises:

a scattering element positioned between said aperture and said distal end of said applicator.

6 . An energy transmission applicator according to claim 1 wherein said cooling circuit further comprises:

a cooling chamber positioned between said antenna aperture and a proximal side of said cooling plate.

7 . An energy transmission applicator comprising:

a disposable interface at a distal end of said applicator, said disposable interface comprising a disposable engagement mechanism;

a waveguide assembly including a plurality of antenna apertures arranged to transmit energy through said distal end of said applicator; and

a cooling circuit including a cooling plate, wherein at least a portion of said cooling circuit is positioned between said antenna and said distal end of said applicator.

8 . An energy transmission applicator according to claim 7 wherein said waveguide assembly comprises:

a plurality of waveguide antennas positioned in an antenna cradle;

a distribution element arranged to transmit said energy to said plurality of antennas.

9 . An energy transmission applicator according to claim 8 wherein said distribution element comprises a microwave switch.

10 . An energy transmission applicator according to claim 8 wherein said distribution element comprises a power splitter.

11 . An energy transmission applicator according to claim 7 wherein said energy transmission applicator further comprises:

a plurality of scattering elements positioned between said apertures and said distal end of said applicator.

12 . An energy transmission applicator according to claim 7 wherein said cooling circuit further comprises cooling chambers positioned between said antenna apertures and a proximal side of said cooling plate.

13 . An energy transmission applicator according to claim 12 wherein said waveguide assembly comprises:

a plurality of waveguide antennas positioned in an antenna cradle;

a distribution element arranged to transmit said energy to said plurality of antennas.

14 . An energy transmission applicator according to claim 13 wherein said cooling circuit further comprises cooling passages in said antenna cradle, said cooling passages being connected to said cooling chambers.

15 . An energy transmission applicator according to claim 7 wherein said waveguide assembly comprises:

a plurality of waveguide antennas; and a plurality of isolation elements positioned between said antennas.

16 . An energy transmission applicator according to claim 15 wherein said waveguide assembly further comprises a first isolation element positioned at a first end of said waveguide assembly and a second isolation element positioned at a second end of said waveguide assembly.

17 . An energy transmission applicator according to claim 16 wherein said isolation elements comprise a shim of microwave absorption material.

18 . An energy transmission applicator according to claim 16 wherein said isolation elements comprise a microwave choke.

19 . An energy transmission applicator according to claim 15 wherein said waveguide antenna comprises:

an inner dielectric; and

an outer shell surrounding said inner dielectric on every side except said aperture.

20 . An energy transmission applicator according to claim 7 wherein said cooling plate comprises:

a proximal surface;

a distal surface;

one or more thermocouple grooves in said distal surface; and

one or more thermocouples positioned in said thermocouple grooves.

21 . An energy transmission applicator according to claim 20 wherein said thermocouple grooves are arranged parallel to an E-Field emitted by said waveguide assembly when said transmitted energy is microwave energy.

22 . An energy transmission applicator according to claim 20 wherein said microwave energy is transmitted in a TE1O mode.
