1. A urinary incontinence valve disposable in the urethra of a patient for controlling the flow of urine therethrough comprising:
- (a) a tubular body member having a proximal end, a distal end and an outer diameter sufficiently small to allow insertion into the urethra of a patient and a lumen extending longitudinally from said proximal end to said distal end through which urine can flow;
(b) a valve seat disposed in said lumen of said body member proximate said distal end;
(c) a valve member including a valve surface cooperating with said valve seat for normally blocking liquid flow through said lumen;
(d) an actuator rod affixed to said valve member projecting outward of said lumen at said distal end of said body member, said actuator rod including a magnetizable member attached to an end which is opposite an end extending into the lumen; and
(e) stylet means for releasably gripping said proximal end of said tubular body.

Abstract
A urinary incontinence valve for placement in the urethra of a male or female patient and which is magnetically-actuable from outside the body. The valve body is designed to fit into the neck of the bladder and includes an actuator rod which extends out of the valve body and into the bladder itself, providing greater freedom of movement of a valve surface relative to the valve seat. A compression spring normally urges the valve member to its closed position and when so closed, the compression spring is maintained in a urine-free environment.

13. A urinary incontinence valve for positioning in the urethra of a patient and controlling the flow of urine therethrough, comprising:
-
(a) a tubular body member having a proximal end, a distal end and an outer diameter sufficiently small to allow insertion into the urethra of a patient and a lumen extending longitudinally from said proximal end to said distal end through which urine can flow; (b) a generally planar, annular valve seat surface disposed in said lumen of said body member proximate said distal end; (c) a valve member having a generally planar valve surface cooperating with said planar valve seat surface for normally blocking urine flow through said lumen; (d) an actuator rod affixed to said valve member so as to project outward from said distal end of said tubular body member into the urinary bladder of the patient when said body member is in the urethra, said actuator rod supporting a first permanent magnet outside said lumen; and (e) a second permanent magnet which when located exterior of the patient'"'"'s body and proximate to said urinary incontinence valve, attracts said first permanent magnet to tip said actuator rod and said valve member relative to said valve seat surface, permitting urine flow through said annular valve seat surface and said lumen. - View Dependent Claims (14, 15, 16, 17)
