Historical information

This is the 'old' style of Gelhorn pessary, which is similar in appearance to the Matthews-Duncan disc and stem and the Simpson's shelf gutta-percha.
"This type of pessary was used in cases of complete procidenture... thus preventing dragging on the posterior wall of the bladder and the associated incontinence of which most patients complained. When wearing a large pessary with a small pessary, the uterus often came down beside the pessary." (Dr. A.J.Helm-Montigue, Down Bros Ltd. Surgical Instruments and Appliances, p. 1038.
