Abstract
A vaginal pessary (10 or 34) used to control urinary incontinence or a prolapse, which pessary has a hollow annular body (12 or 36) and an elongated fluid conveying flexible elongated tube (16) which may be stored between the upper and lower surfaces of the annular body when the pessary has been properly inserted into the vagina. The annular body is provided with a diaphragm (20) attached to the inner surface (12.2 or 36.2) of the body, the diaphragm having a central aperture (22). The tube (16) has a coiled shape by making the tube from an elastic material having a memory, by having the tube carry a spring wire (18) forming into a coiled shape, or both. In the illustrated embodiments, a one way valve (24) is provided in an end portion (16.2) of the tube. The valve may be opened by inserting a hypodermic needle carried by a syringe to either cause the body (16) to assume its normal operational volume or to have its volume reduced for insertion or removal. After the annular body has been inserted and it is has attained its normal operational volume, the tube is released and it returns to its coiled shape, retracting into the vagina. Digital manipulation may encourage the coiled tube to fully retract. When the pessary is to be removed, a finger, directed through loops of the coil, will pull out the tube with its valve which reaches well outside the vagina for easy attachment to a hypodermic needle. Fluid may now be withdrawn from the annular body, thereby permitting easy removal.
