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 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.
Claims7
A method of forming a custom-fitted cervical cap in situ, within a patient's body, comprising the steps of
- (a) positioning a first rim member, having a predetermined inner diameter, around the patient's exocervix;
- (b) determining whether the rim member fits snugly around the patient's exocervix;
- (c) if the first rim member does not fit snugly, removing the first rim member and positioning a second rim member, having an inner diameter smaller than that of the first rim member, around the patient's exocervix;
- (d) repeating steps (b) and (c) for each successive rim member, until a rim member is found which fits the exocervix snugly, said rim member including one or more ridges on its inner surface to securely grip the exocervix;
- (e) selecting a shell member which is dimensioned to be mounted sealingly onto the rim member which fits the exocervix snugly, the shell member including an aperture;
- (f) mounting the shell member onto the rim member such that the rim member, the shell member and the exocervix define a cavity;
- (g) injecting a curable material through the aperture to substantially fill the cavity;
- and
- (h) allowing the curable material to harden and removing the shell member, the hardened curable material and the rim member, in combination, forming the custom-fitted cervical cap.
