We describe two unusual cases; both patients wish to continue using the Gynefix despite experiencing difficulty with the device. In case A, the marker string of the Gynefix(R) perforated the full thickness of the cervix and was visualized on the left lateral aspect of the cervix. Three months later the string had moved again and could no longer be visualized, but an ultrasound scan confirmed fundal implantation of the device. Case B demonstrates repeated late expulsion and failure of implantation of Gynefix. Appropriateness of ultrasound with reference to measurement of the distance SS (between the peritoneal surface of the uterine fundus and the first copper sleeve of the Gynefix), failure of implantation and problems with the new Gynefix introducer are discussed.
