摘要：
A flexible implantable contraceptive disc device can be inserted inside the female body. The circular device can be bent and inserted into a laparoscopy tube, which allows it to be delivered to the appropriate location inside a female subject. The disc has three layers, a central core silicon reservoir containing the active ingredient, such as a contraceptive, 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 the circumference, allowing the disc device to be attached to a desired tissue by rotating the disc such that the hooks engage with the tissue. Such a device is easier to insert, and to remove, than the rod-like rigid plastic T-shape IUDs which are considerably larger and more expensive to manufacture.
