A method for promoting contraception by placing a contraceptive device within a uterus without blocking fallopian tubes may involve advancing a distal end of a delivery device through a cervix, advancing the contraceptive device comprising an elongate shape memory member out of the distal end of the delivery device and into the uterus, and limiting inferior migration of the contraceptive device within the uterus. Inferior migration may be limited by allowing the contraceptive device to assume a shape, when subjected to pressure that tends to cause a downward migration of the device within the uterus, in which an expandable middle portion of the device is expanded to contact the inner wall of the uterus and thus limit the downward migration of the device.
