Abstract
An electrified vaginal ring comprising an annular ring member fabricated of a medical grade polymer, elastomer, silicone or other comparable plastic material which is compatible with human tissue and fluids and physically proportioned to fit within the vagina of a female human being or other mammal while surrounding the cervix. The annular ring member has at least two physically spaced-apart, electrically conductive surfaces preferably in the form of spaced-apart bands of conductive material extending around either the periphery of the central opening through the annular ring member, or around the outside perimeter of the annular ring member. The electrically conductive surfaces may be comprised of platinum, a platinum alloy, or other comparable electrically conductive material that is electro-deposited, sprayed or otherwise secured to the annular ring member with the conductive material also being compatible with human tissue and fluids. At least one miniaturized electric cell or a plurality of such cells interconnected to form a miniaturized battery is molded within the body of the annular ring member with respective one of its opposite polarity terminals electrically connected t…
