Title (EN) IMPLANTABLE MEDICAMENT DELIVERY SYSTEM
(FR) SYSTÈME DE DISTRIBUTION DE MÉDICAMENT.
Abstract:
(EN) A flexible implantable contraceptive disc device is disclosed which can be inserted inside the female body, such as inside the uterus, is disclosed. 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 progesterone, which is sandwiched and encased by an 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 discs 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, also more expensive to manufacture.
(FR) L'invention concerne un disque contraceptif implantable flexible qui peut être inséré dans le corps d'une femme, par exemple à l'intérieur de l'utérus. Le dispositif circulaire peut être plié et inséré dans un tube de laparoscopie, ce qui lui permet d'être placé à l'endroit approprié à l'intérieur du sujet féminin. Le disque comprend trois couches, un réservoir central de silicone contenant le principe actif, tel que de la progestérone contraceptive, qui est pris en sandwich et entouré par un boîtier de silicone perméable supérieur et un inférieur. Les boîtiers sont perméables au contraceptif, permettant une libération contrôlée sur une période de temps prolongée. Le boîtier inférieur a une série de micro-crochets le long de la circonférence des disques, permettant au disque d'être fixés au tissu souhaité en le tournant de sorte à ce que les crochets s'attachent au tissu. Un tel dispositif est plus facile à insérer et à retirer que les dispositifs intra-utérins plastiques en forme de T de type tige rigide qui sont considérablement plus grand et plus coûteux à fabriquer.
