Abstract: A frame of an intrauterine system which includes an elongate member having at its first end a transverse member including a first wing and a second wing, first ends of the wings being attached to the elongate member. The first and second wings are symmetrically bent towards a second end of the elongate member so that an angle a formed between the elongate member and the first or second wing is 10°-60°. The second ends of the wings are symmetrically bent towards the elongate member by an angle ? that is 40°-140°.

Abstract: A vaginal device provides physical and chemical barriers to contraception or protection against sexually transmitted diseases, or both. The device includes a towelette having approximately 1 to 10 ml of preventive formulation incorporated therein by absorption. During intercourse, the towelette rests in the upper vagina and effectively functions as both a physical and chemical barrier to contraception. In some embodiments, the towelette may become compressed into a crumpled, disc-like shape, which may enhance its properties as a physical barrier. In other embodiments, the vaginal device includes a flexible ring that is affixed to the towelette to define a dome-shaped towelette portion on one side of the ring and a depending skirt on the other side, with the dome portion being designed to cover the cervix. Means to facilitate insertion and removal of the device are described.

Abstract: A vaginal device provides physical and chemical barriers to contraception or protection against sexually transmitted diseases, or both. The device includes a towelette having approximately 5 ml of preventive formulation incorporated therein by absorption. During intercourse, the towelette rests in the upper vagina and effectively functions as both a physical and chemical barrier to contraception. In some embodiments, the towelette may become compressed into a crumpled, disc-like shape, which may enhance its properties as a physical barrier. Means to facilitate insertion and removal of the device are described.

Abstract: This invention relates to a medicated device for insertion into the uterus or cervix comprising a T-shaped platform and a drug release attachment thereon, the platform having a vertical stem portion with a rounded knob portion at the top thereof and two flat flexible downwardly slanting arms extending from the knob, the arms tapering to a lesser dimension at the end from the knob to the end of the arms and the arms having a downward bend of about 45.degree.-110.degree. proximate the end of each arm.
