A plastic frame for an intrauterine device

The invention relates to a new intrauterine platform for the delivery of bioactive substances in the uterine cavity. The intrauterine system or device (IUD) basically consists of a plastic frame (2) which is affixed to a drug delivery compartment (1) of various dimensions. The purpose of the plastic frame is to retain the IUD in the uterine cavity and prevent displacement and expulsion. The plastic frame is shaped like the letter omega consisting of two arms which are resilient and have the characteristic of possessing latero-lateral memory. The extremities of the arms are provided by a short side-arm (6) 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 plastic frame adapts to cavities of every size, maximizing tolerance. The drug delivery compartment is provided with a means 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.
