Implantable Drug Delivery System |
| abstract |
A flexible implantable contraceptive disc device is disclosed that can be inserted into a female body, such as in the uterus. The circular device can be bent and inserted into the laparoscopic tube to allow the device to be delivered to the appropriate location within the female subject. The disk consists of three layers, the core silicon reservoir in the middle is sandwiched between the upper porous silicon shell and the lower porous silicon shell and surrounded by the upper porous silicon shell and the lower porous silicon shell, and the silicon reservoir contains the active silicon Ingredients, such as the birth control pill progesterone. The housing is permeable to the contraceptive for controlled release of the contraceptive over an extended period of time. The lower housing has a plurality of micro-hooks surrounding the disc to allow the disc device to be attached to tissue by rotating the disc to engage the micro-hooks with the desired tissue. This device is easier to insert and remove than a rod-shaped rigid plastic T-shaped IUD, which is relatively large and more expensive to manufacture. |
