INTRAUTERINE DEVICE WITH RETRIEVAL THREAD

摘要

An intrauterine contraceptive system may include a contraceptive intrauterine device, a retrieval thread permanently attached to the intrauterine device and an insertion device for inserting the intrauterine device into a uterus. The system may also include a release thread releasably coupled with the intrauterine device. The intrauterine device may be deployable out of a distal end of the insertion device and may be configured to change from a delivery configuration when housed in the insertion device to a deployed configuration when deployed in a uterus. The retrieval thread and the optional release thread may be at least partially housed within the insertion device during insertion of the intrauterine device into the uterus. The release thread may extend from the intrauterine device through the insertion device to an attachment point at or near a proximal end of the insertion device.

主权项

1. A method for delivering a contraceptive intrauterine device into a uterus, the method comprising:
advancing a distal end of an insertion device through a vaginal cavity and a cervix and into the uterus; advancing the intrauterine device out of the distal end of the insertion device, into the uterus, wherein the intrauterine device is permanently attached to a retrieval thread and removably coupled with a release thread; pulling the release thread off of the intrauterine device; and removing the release thread and the insertion device from the uterus, leaving the intrauterine device behind in the uterus, without cutting the retrieval thread, wherein the retrieval thread extends from an attachment point of the retrieval thread with the intrauterine device through the cervix into the vaginal cavity.
