ABSTRACT:
Apparatus for applying electromagnetic radiation to the pelvic cavity is described, which comprises a first electrode (12) which is inserted into the pelvic cavity (10) in use. A second electrode (14) is also provided and an electromagnetic generating cicuit (1, 2, 6, 9) is coupled to each electrode (12, 14). The frequency generated by the generating circuit (1, 2, 6, 9) in use is emitted by one of the electrodes (12) and received at the other electrode (14) so that the temperature of the cells adjacent to the first electrode (12) is increased above the normal cell temperature. The apparatus is particularly useful for exposing the endometrium to histotoxic temperature and to thus achieve endometrial destruction. Typically, the electromagnetic radiation is radio frequency radiation which is preferably in the range of 500 kHz to 500 MHz. The end (22) of the first electrode (12) may be curved in order to allow access to the cornua regions of the uterine cavity and to improve endometrial contact.
