| 20110253148 | PLASTIC FRAME FOR AN INTRAUTERINE DEVICE - An intrauterine device for delivering bioactive substances in the uterine cavity includes a plastic frame affixed to a drug delivery compartment. In use, the frame retains the IUD in the uterine cavity and prevents displacement and expulsion. The frame is shaped like the letter “omega” having two resilient arms which possess latero-lateral memory. The extremities of the arms are provided by a short side-arm which forms an angle with the rest of the arm. These prominent plastic parts facilitate the upward rotation of the arms during removal of the intrauterine device. Due to the resilience of the arms, the frame adapts to cavities of every size, maximizing tolerance. The drug delivery compartment has an element at its upper extremity to determine the exact location of the IUD in the uterine cavity by ultrasound. The drug delivery compartment contains one or more drugs which are gradually released in the uterine cavity over extended periods of time. | 10-20-2011 |
