ABSTRACT:
A method is provided of forming a cervical cap in situ, i.e., within a patient's body, which cap will substantially completely conform to the shape of the patient's cervix, allowing the cap to be left in place over an extended period of time. The method of the invention includes the steps of positioning a snugly fitting rim member around the patient's exocervix, mounting a shell member, having an aperture, onto the rim member such that the rim member, shell member and exocervix define a cavity, and injecting a curable material through the aperture to substantially fill the cavity. After the curable material is allowed to harden, the entire assembly is removed from the patient and the shell removed from the cured material.
