Historical information

This was one of the older types of ring pessary and resembles a watch spring pessary. They were made in a wide variety of sizes and thicknesses, and came either just as a ring or with a perforated indian rubber septum.

A new type of ring pessary was later made which improved on this design. Whereas this hard rubber/vulcanite style pressed on the vaginal wall, the new style instead provided a soft cushion thanks to a patent fluid filled design. This meant that the pessary did not collapse in the way air filled pessaries did, and meant that the pessary could remain in place for a much longer period without discomfort to the patient.

Physical description
