Abstract
Abstract An intrauterine contraceptive device comprising an elongated shank having divergent convoluted portions at its distal end, the convoluted portions being generally sinusoidal in nature, the device having incorporated in the shank a permanent magnet and having a substantial portion of its surface covered with a biologically inert, silicone elastomeric material which may contain an analgaesic or anti-fertility agent which is gradually released in utero. In a preferred embodiment of the invention, the proximal end of the shank contains a pair of downwardly extending divergent, resilient legs which tend to prevent inadvertent expulsion of the device. In another preferred embodiment, the lower end of the device is formed with a small container for certain types of medication which are released gradually into the vagina over a prolonged period of time for the prevention and cure of such diseases as gonorrhea and syphilis.
