Abstract
Abstract A conforming valved cervical cap assembly is provided with an elastomeric inner layer molded and cured in situ adjacent the exocervical surface of a cervix uteri. The inner layer is wettable, non-porous and matingly fits and resiliently complements the exocervical surface. In order to prevent the molding material from clogging or otherwise impairing operation of the valve, a valve cover is detachably connected to the valve during molding and curing.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
65 words
A cervical cap assembly, comprising: a flexible shell having a concave inner surface and one-way valving means operatively associated with said shell for permitting egress of uterine discharges but preventing ingress of sperm; and a liquid impervious, non-porous elastomeric lining on said concave inner surface defining a wettable, matingly fitting and resiliently complementing contact surface permanently contoured for the exocervical surface of a cervix uteri.
Claim 2
Dependent Claim
65 words
A cervical cap assembly, comprising: a flexible shell having a concave inner surface and one-way valving means operatively associated with said shell for permitting egress of uterine discharges but preventing ingress of sperm; and a liquid impervious, non-porous elastomeric lining on said concave inner surface defining a wettable, matingly fitting and resiliently complementing contact surface permanently contoured for the exocervical surface of a cervix uteri.
Claim 3
Dependent Claim
17 words
A cervical cap assembly in accordance with claim 1 wherein a flexible skirt depends from said shell.
Claim 4
Dependent Claim
21 words
A cervical cap assembly in accordance with claim 2 wherein said flexible skirt is provided with a plurality of spaced slits.
Claim 5
Dependent Claim
91 words
A cervical cap assembly, comprising: a flexible, non-porous shell having a concave inner surface and one-way valving means for permitting egress of uterine discharges but preventing ingress of sperm; a flexible, liquid impervious, non-porous liner sheath connected to said shell for positioning against the exocervical surface of a cervix uteri; and an intermediate resilient elastomeric cushion positioned between said concave inner surface and said liner sheath, said cushion having an exocervical-fitting permanently contoured surface adjacent said liner sheath for matingly fitting and resiliently complementing the exocervical surface of the cervix uteri.
Claim 6
Dependent Claim
91 words
A cervical cap assembly, comprising: a flexible, non-porous shell having a concave inner surface and one-way valving means for permitting egress of uterine discharges but preventing ingress of sperm; a flexible, liquid impervious, non-porous liner sheath connected to said shell for positioning against the exocervical surface of a cervix uteri; and an intermediate resilient elastomeric cushion positioned between said concave inner surface and said liner sheath, said cushion having an exocervical-fitting permanently contoured surface adjacent said liner sheath for matingly fitting and resiliently complementing the exocervical surface of the cervix uteri.
