  • Patent number: 4066075
    Abstract: A nonobstructive U-shape intravaginal device adapted to be placed in the vagina of a female mammal so that the arcuate-shape, closed-end portion of the device is disposed in the posterior fornix of the vagina, and so that the spaced arms of the device extend generally towards the introitus of the vagina and are adjacent the lateral walls of the vagina. When thus disposed, the device does not materially obstruct the portion of the vagina anterior of the cervix uteri and thus would not be a source of interference or discomfort during sexual intercourse. The device may comprise an effective charge of such beneficial materials as medicaments, contraceptives, or deodorants or the like within a sufficiently permeable structure that the charge is released over an extended period of time by the action of body fluids on the device whereby sustained beneficial effects are achieved.
