ABSTRACT:
The invention relates to an intrauterine contraceptive device having at least two flexible arms. The contraceptive device is provided with at least two almost horizontal arms having solid tips. The arms, are provided at the front and back with cavities in longitudinal direction. The central point of the contraceptive device is provided with a flexible thread, surrounded by a device acting as contraceptive. The active device may consist of copper rings, which rings are retained by a holding means located below the thread. Next to copper rings a flexible tube provided with openings may be used, into which an active contraceptive drug, for instance a hormone preparation, is inserted. An important advantage of the contraceptive device according to the invention is the absence of the vertical stem of the IUD. The arms and the central point of the contraceptive device are made from a flexible synthetic material which is tolerated by the uterus, preferably from polyethylene. The thread is also usually made from a synthetic tolerated by the uterus, preferably from nylon.
