The FlexiGard 330 ICC, an ultrasound evaluation.

The FlexiGard 330 intrauterine copper contraceptive (ICC) was studied by ultrasound in 405 patients immediately following insertion and at each follow-up visit, for up to 5 years. The present study confirms the validity of the anchoring concept for the suspension of bioactive substances in the uterine cavity. The major conclusion from the study is that the anchor is non-migrating even when observed over a long period of time. Ultrasound examination is the method of choice to evaluate proper insertion technique as well as proper positioning of the device at follow-up.
