摘要
A new and improved hybrid “framed-frameless” copper-releasing contraceptive device (IUD) which is a combination of a plastic retention arm of reduced dimensions to adapt to uterine cavities of smaller size, particularly regarding their transverse width at the fundal level of the uterus, and whose retention arm has a centrally located extension of varying length to be connected with hollow copper tubes which functions as the frameless stem of the IUD, and which consists of loosely connected hollow tubes, threaded on a length of suture, or a thin plastic or metallic stem, or a thin polymeric drug eluting stem, allowing release of copper ions, from the outside and from the inside of the tubes, in the uterine cavity thereby enhancing the contraceptive effect, and of which the bottom tube, is crimped onto the lower end of the stem, including a separate metallic ion-releasing fiber, holding all copper tubes together.
