ABSTRACT:
A removable elastomeric cervical cap includes a thin-walled cap-shaped member having the same shape as the exocervix and having an inside surface conforming identically to the exocervix surface. The method includes expanding the vaginal wall to substantially expose the exocervix surface. A layer of a liquid self-curing elastomeric material is then applied to only the exocervix surface, the inner surface of the layer conforming identically to the surface without distorting the surface. The liquid elastomeric material is then permitted to solidify.
