发明名称 Conforming valved cervical cap assembly and in-situ molding method
摘要 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, nonporous 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.
