<p>A microwave applicator able to be introduced into hollow anatomical structures such as varicose veins comprises a co-axial cable 204 feeding microwave energy form a generator to the emitter probe 1 1''. The central conductor 210 of the co-axial cable extends into a conically tapering dielectric member 208; the conductor either fully or partially extending within the dielectric member. There is provided a temperature sensor within the probe, which may be a thermocouple provided on ferrule 206. The co-axial feed cable may be marked such that movement of the probe through a vein and thus traversal of a varicose treatment site may be more easily controlled (see figures 6 and 7) to provide uniform application of radiation.</p> |
