TREATMENT APPARATUS

摘要

A probe (1) is designed to propagate and radiate microwave electromagnetic e nergy in a controlled fashion. The probe (1) includes at least one waveguides (2) of cross-section which would not normally pass m icrowaves at the operational frequency. The waveguide (2 ) therefore includes dielectric material (5), such as alumina, in the form of a rod an exposed portion of which forms an antenna. The probe is preferably for use in endometrial ablation and therefore the reduced dimensi on of the waveguide can be made compatible with the narr ow neck of the uterus.
