ABSTRACT:
A vaginal device adapted for use as a disposable female contraceptive or as a disposable article for controllably dispensing drugs is provided comprising an outermost layer of resilient, compressible open-celled polymeric foam. Affixed to the outermost foam layer is a non-porous film layer made of a liquid proof, soft elastomeric material. Affixed to the non-porous film layer is another layer of open-celled polymeric foam. The intermediate film layer provides a barrier between the two foam layers. The outermost and innermost foam layers are formed from foams differing basically in density and/or number of pores per inch, with the more dense or smaller pored foam constituting the outermost layer, the outermost layer being adapted to lie against the cervix of the uterus and block the upper vaginal vault.
