<p>A surgically implantable urethra pressure control adjustable valve for male and female patients is described. The valve comprises a clamp positionable about a urethra in a patient's body. The clamp has a circumferential wall having a first and a second opening. The openings are oppositely spaced-apart at predetermined locations to provide for the passage of the urethra through the circumferential wall. A pressure abutment element is provided inside the circumferential wall and disposed between an inner wall surface of the circumferential wall and the urethra and actuable to apply a contained control pressure against the urethra to close the urethra by pinching same against a diametrically opposed immovable abutment element formed in the circumferential wall and projecting inwardly therein. The contained controlled pressure is adjustable and selected so that liquid pressure from a bladder associated with the urethra and under the influence of muscle control will cause the urethra to open against the contained controlled pressure to discharge liquid from the bladder and to automatically close once the pressure from the bladder is discontinued by muscle control.</p> |
