The frameless coil (Gynefix®) presents a new alternative to the common coil. It consists of six small copper clyinders stringed along on a nylon string. The framless coil is fixed to the wall of the uterus, lying free in the uterus and adapts to it. Therefore, menstrual disorders and pain are rare. Just like the common coil, it can remain in the uterus for up to five years. The frameless coil has a very low failure rate. Pearl index is between 0,1 and 0,3. So, the frameless coil is safer than the common coil.
