Intracervical anchoring: a new approach to intrauterine contraception.
The intracervical device described in this paper consists of copper wire around a small plastic frame that is anchored to the inner wall of the cervix, at about 1.5 cm from the external os. The device represents a radical departure from conventional intrauterine contraception and 'frameless' IUDs, which are anchored to the uterine fundus. The device was evaluated in a preliminary study of 11 women. During the 3-month evaluation period, there were no expulsions or removals for any reason. The device was well tolerated. Expanded clinical trials are planned.
