Abstract
An electrified intrauterine device (IUD) is provided which has an IUD body member fabricated from materials which are physiologically compatible with human tissue and fluids and physically proportioned to be placed and retained within the uterus of a female mammal. Spaced-apart electrically conductive electrodes are formed on the IUD body member from electrically conductive materials that are physiologically compatible with human tissue and fluids. Self-contained electric batteries are supported within the IUD body member that forms a sealed outer casing of biologically inert material compatible with human tissue and fluids. The batteries are capable of producing an electromotive force of known voltage and current rating and are of a size to be inserted and retained within the uterus of a female mammal. The device is completed by electrically conductive interconnecting conductors between respective opposite polarity terminals of the batteries and respective ones of the spaced-apart electrically conductive electrodes on the IUD body member whereby an electric field force can be established and maintained within the uterus of a female mammal in which the electrified IUD is inserted.
