Abstract

A SEM study carried on intra-uterine devices (Dalkon Shield) is reported. The poor manufacturing of the devices is stressed, which could increase their efficiency but also the risks of penetration, or worse, perforation. The solution for the future could be copper bearing intra-uterine devices coated by hydrogels. This should maintain efficiency and improve security.
