Abstract
Abstract Contraceptive intrauterine means is constructed to permit a surgeon when the uterine cavity is enlarged after birth to manually attach a foreign object to the uterine cavity wall by a hook, coupled thereto, thereby to control fertility. A truncated cylindrical member fits on the surgeon's finger for movement axially in a concentric outer cylindrical guide when a detent position is overcome by manual force as the guide frontal portion engages the uterine wall. The hook is removably attached to the truncated cylindrical member so that as it moves to a position beyond the guide it can become embedded into the uterine wall and the cylindrical members are removed leaving the intrauterine means in place.
