After more than a decade of basic research with the help of cavimetry, retentiometry, X-ray and ultrasonography, a new intrauterine contraceptive device, the CU SAFE IUD, was developed. The plastic body of the device shows the following properties: uterine cavity compatible, enhanced flexibility, low surface area, fundus-seeking anti-expulsive design, no anchoring mechanisms, and one monofilament without a knot embedded into the shaft. The copper surface area of 300 mm2 guarantees a high efficacy for up to five years. The CU SAFE 300 IUD fulfils all requirements of the International Organization for Standardization (ISO) in regard to intrauterine devices. |
