PCT No. PCT/GB94/01565 Sec. 371 Date Apr. 29, 1996 Sec. 102(e) Date Apr. 29, 1996 PCT Filed Jul. 19, 1994 PCT Pub. No. WO95/04385 PCT Pub. Date Feb. 9, 1995A probe (1) is designed to propagate and radiate microwave electromagnetic energy in a controlled fashion. The probe (1) includes at least one waveguide (2) of cross-section which would not normally pass microwaves 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 dimension of the waveguide can be made compatible with the narrow neck of the uterus. |
