Abstract
An intrauterine contraceptive device is provided which is inserted into a uterus in a collapsed position and held in expanded position by a locking means which prevents any further expansion of the IUD and limits the pressure exerted thereby on the uterine wall. The locking means, however, permits the IUD to collapse upon contraction of the uterus. The locking means may take the form of a string fixedly connected to one arm of the IUD and slidably attached to the other arm to be fixed in position upon initial expansion of the IUD by a quick setting adhesive or by means of an interengaging beaded chain and slot arrangement. The arms of the IUD can also be telescopically expandable in a longitudinal direction and fixed in expanded position once the ends of the arms come into engagement with the uterine wall but can collapse in response to uterine contractions.
