It is held in place by a suture (knot) to the fundus of the uterus. It is mainly available in China and Europe. A framed copper IUD called the IUB SCu300 coils when deployed and forms a three-dimensional spherical shape. It is based on a nickel titanium shape memory alloy core. In addition to copper, noble metal, and progestogen IUDs, women in China can get copper IUDs with indomethacin.
