With the copper pearls ball IUB (IntraUterine Ball), several small copper pearls are mounted on a wire covered with plastic. The wire has a so-called shape memory and, as soon as it has been inserted into the uterus through a small tube, returns to its original shape of an approx. 1.5 cm ball. This gives it a secure position in the uterus.
