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.

Abstract: A medical locking device securely fits onto finger grips of a syringe. The locking device is axially aligned with the syringe along a defined longitudinal axis wherein the syringe receives a plunger. The locking device includes a centrally positioned aperture which receives the shaft of the plunger. A retaining member is positioned around the aperture and receives the finger grips of the syringe by engaging at least three sides of the finger grips. This eliminates shifting of the medical locking device and there are opposed cutting members which are chordally positioned in the aperture. The cutting members taper as fine cutting edges for wedging into the plunger during execution of a locking position. To utilize the device, the user twists the plunger into a locking position so that the cutting members wedge into the plunger. This locking position eliminates and prevents any further plunger movement in either direction along the longitudinal axis.
