Intrauterine contraceptive device

Abstract

Abstract The intrauterine contraceptive device to be inserted in the uterus comprises a supporting stem (1) having two branches (4) disposed at the front end (3) thereof in the direction of insertion. Each of the branches bears at its free end a permanent closure member (7). The closure members are intended to seal the mouths of the Fallopian tubes into the uterus. Each closure member is made of a soft material and has a substantially spherical or tear-shaped form. Fixed to these closure members is a temporary holding and positioning rod (9) of flexible, resorbable material, e.g., of collagen or polyglycolic acid, in such a way that this holding and positioning rod, together with the supporting stem (1), forms the shape of a T, the positioning ends (10) of the holding and positioning rod (9) being farther apart than the permanent closure members (7). The intrauterine contraceptive device is suitable for use immediately after a pregnancy. Insertion in the uterus is easily possible at that time through the still open uterine orifice without the diameter of the insertion means having to be kept minimal. Moreover, the temporary holding and positioning rod takes over the function of a sealing means for the mouths of the Fallopian tubes. It also retains this function during its biodegradation, during the interval when the uterus, still stretched after the pregnancy, undergoes involution within a period of six weeks. Thereafter, the permanent closure members (7) take over the sealing function.
