ABSTRACT:
A contraceptive diaphragm having a rim surrounding a thin membrane, the membrane having a cervical dome extending downwardly from a posterior portion of the membrane. The rim has two curvilinear bands joined together at their respective ends and encased in a coil spring. The shape of the bands creates a rim which curves slightly upwardly at the anterior end of the diaphragm and slightly downwardly at its posterior end. The rim is formed with a curvilinear profile which provides an advantageous fit. A small dome projects upwardly from an anterior portion of the membrane which is grasped by the wearer to remove the diaphragm.
