Abstract: A disposable IUD/IUS inserter is for use in conjunction with a hysteroscope, or blindly, including an inner part which has a flexible metal inner tube, between 1 and 2 mm in diameter. The inner tube has a front end portion including a stylet, the stylet being less than 1 mm in diameter, and the stylet being provided with a stylet tip. The IUD/IUS inserter is further provided with a handle at a rear end of the inner tube, a handle unlocking mechanism for positioning of an IUD or IUS, a release mechanism for releasing of a tail of the IUD/IUS, and an outer tube sized to allow passage through a hysteroscope working channel, the handle unlocking mechanism being connected to the outer tube.

Abstract: A new and improved hybrid “framed-frameless” copper-releasing contraceptive device (IUD) which is a combination of a plastic retention arm of reduced dimensions to adapt to uterine cavities of smaller size, particularly regarding their transverse width at the fundal level of the uterus, and whose retention arm has a centrally located extension of varying length to be connected with hollow copper tubes which functions as the frameless stem of the IUD, and which consists of loosely connected hollow tubes, threaded on a length of suture, or a thin plastic or metallic stem, or a thin polymeric drug eluting stem, allowing release of copper ions, from the outside and from the inside of the tubes, in the uterine cavity thereby enhancing the contraceptive effect, and of which the bottom tube, is crimped onto the lower end of the stem, including a separate metallic ion-releasing fiber, holding all copper tubes together.

Abstract: An intrauterine device (IUD) for delivering bioactive substances in the uterine cavity includes a plastic frame affixed to a drug delivery compartment. 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. 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.

Abstract: A frameless copper-releasing contraceptive IUD or a hormone-releasing contraceptive IUS, includes a suture thread (3), supporting the active component(s) and an anchor (5) to be inserted in the wall of the uterus with a specially designed applicator or inserter in order to secure the IUD/IUS in the uterine cavity. The anchor consists of a knot made at one end of the thread. A tiny metal tube (6), preferably of stainless steel, is threaded onto the thread and fixed immediately below or above the anchoring knot to make the anchor visible on ultrasound and/or x-ray. The anchoring knot may be provided with a tightly fitting ogival, bell or cone-shaped cap consisting of a biodegradable polymer. The active element (2) consists for example of a succession of threaded copper cylinders.

Abstract: 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.
