A method and apparatus is provided for non-surgical reversible sterilization of females. In the method of this invention an apparatus to which a removable tip is attached is inserted into the uterus. The tip is aligned with the uterine end of the oviduct. A curable elastomeric composition is injected, through an aperture in the tip, into the oviduct in an amount sufficient to fill the portion of the oviduct adjacent to the uterus. The elastomeric composition is allowed to solidify and adhere to the above noted tip. The apparatus is then removed with the tip being ejected from the apparatus so as to remain adhered to the resulting oviduct block. The above procedure is repeated for the opposite oviduct. The resulting oviduct blocks prevent the passage of ovum from the ovaries to the uterus and sperm from entering the oviduct thereby preventing conception. The oviduct blocks if desired can be removed non-surgically by utilizing an apparatus which grips the tip portion of the oviduct block and extracts the entire oviduct block from the oviduct. |
