INTRA-URETHRAL VALVE WITH INTEGRAL SPRING |
摘要 |
A prosthetic urethral sphincter valve with an integral spring valve member which comprises an elastic valve element having an upper portion which defines a central fluid passage and a lower diaphragm portion which includes a rolling diaphragm. The prosthetic urethral sphincter valve is placed totally within a patient's urethra. The lower diaphragm portion of the elastic valve element includes a tapered wall structure which provides for a spring action which demonstrates a non-linear force curve. The central fluid passage assumes a kinked or closed position, or a straighten or open position depending upon the position of the rolling diaphragm. Applied bladder pressure effects the position of the rolling diaphragm and thus the opening and closing of the central fluid passage. |
