Abstract
Abstract A contraceptive device for females comprising a toroidal collar having an anterior portion, a posterior portion, an internal wall, and an external wall, the internal wall having an internal diameter sufficient to surround the cervix and the external wall having an outside diameter such that the anterior and posterior fornices are substantially filled by the collar. The posterior portion is in the posterior fornix and the anterior portion is in the anterior fornix. There is a bowl, below the cervix, on the collar and extending downwardly therefrom. A valve depends from the lower portion of the bowl and is connected therewith, thereby to allow flow from said bowl into the vagina but restricting or preventing entry into the bowl from the vagina. A projection is attached to the collar or the bowl extending anteriorly of the device, whereby reversal of the device and/or substantial rotation thereof around the cervix is prevented. It also assists in removal thereof. The projection may be a loop, preferably having thickened sides to aid in preventing unwanted movement of the device after insertion.
