Abstract: A flexible implantable contraceptive disc device is disclosed which can be inserted inside the female body, such as inside the uterus, is disclosed. The disc device can be bent and inserted into a laparoscopy tube, which allows it to be delivered to an appropriate location inside a female subject. The disc device has three layers, a central core silicon reservoir containing an active ingredient, such as a contraceptive progesterone, which is sandwiched and encased by upper and lower porous silicon casings. The casings are porous to the contraceptive, allowing controlled release over a prolonged period of time. The lower casing has a series of micro-hooks around a circumference, allowing the disc device to be attached to a desired tissue by rotating the disc device such that the hooks engage with the desired tissue. Such a device is easier to insert, and to remove, than a rod-like rigid plastic T-shape IUDs which are considerably larger, also and more expensive to manufacture.
