<p>The applicator is suitable for killing or reducing bacteria or viruses contained inside the human body, and may also be used externally. The applicator comprises an integrated cable assembly carrying both microwave RF energy and gas to an antenna structure which creates a plasma. The applicator and antenna may be integrated and so be suitable for direct insertion through natural orifices of the human body, or endoscopically. The cable assembly comprises a microwave connector 340, a first tube 304 made from a dielectric material and coated on the inside and the outside with metallic coatings 308, 309 and with a hollow channel 301 transporting gas to the antenna. The first tube also forms a coaxial waveguide for feeding microwave energy to the antenna. This first tube may be located in a second tube 303 with spacers 302 providing a second channel 307 for extracting gas. The antenna may comprise a first 310, 330 and second 320,330 impedance transformers producing an electric field capable of producing a plasma suitable for sterilisation.</p> |
