ABSTRACT:
A pessary for treating uterine prolapse and/or stress urinary incontinence. A first embodiment of the pessary basically comprises a base ring, a sling support, and a sling membrane wall secured together to form an integral unit. The unit is formed of a biocompatible, flexible material, e.g., medical grade silicone, so that it can be collapsed or folded. The base ring is annular member defining a plane. The sling support is an arcuate portion of a ring having a pair of ends secured to the base ring so that the sling support is oriented in a plane extending at an acute angle, e.g., 33 degrees, to the plane of the base ring. The sling membrane is supported between a portion of the base member and a portion of the sling support to forms an arcuate wall of the periphery of the pessary. When the pessary is in place the sling wall presses against the inter-vaginal wall, thereby gently closing the urethra. At the same time the ring base member provides support for the uterus, preventing further migration or prolapse. A second embodiment of the pessary is identical to the first embodiment but includes an additional membrane or wall to provide additional support useful for treating greater degrees of uterine prolapse than the first embodiment.
