title: The Copper-Fix (Cu-Fix): a new concept in IUD technology.
abstract: The Copper-Fix (Cu-Fix) is a thread-type copper-bearing device designed to overcome the most common IUD-related problems: bleeding and pain. Two distinctive features--virtual absence of a frame and provision of an anchoring system--make this new intrauterine device the first radical departure from current IUD technology. The Cu-Fix 390 was inserted at intervals in 382 women, and 4851 woman-months of experience had been accumulated at 18 months. The device was exceedingly well retained by the uterus (expulsion rate 0.6 at 18 months) and the removal rate for bleeding/pain was low (3.1 at 18 months). Serious complications did not occur; the pregnancy rate amounted to 0.3 at 18 months, with a continuation rate of 87.6%, which includes an 8.1% removal rate for pregnancy wish. Cardinal event rates were not influenced by the age or gravidity status of the recipient.
