A three-dimensional intrauterine contraceptive device which conforms in an infinite manner to the internal geometric shape of the uterine cavity. The device is comprised of a plurality of resilient interconnected rib-like members which define a generally cylindrical-type shape. The device is inserted into the uterine cavity in a compressed condition. Upon release from a holder the device expands outwardly engaging the walls of the uterine cavity to provide an effective contraceptive device.
