Abstract
An urethral magnet valve for insertion into the urethra of a person suffering from incontinence defines a binary duct relief valve comprising a nonferromagnetic tubular housing containing a valve member of a permanent magnet encapsulated within a nonmagnetic material, enabled on a valve seat of high magnetic permeability ferromagnetic nature, by a magnetic attraction therebetween. Retaining flanges integral with the housing prevent escape of the valve element when valve is open. A manually held external positioned permanent switching magnet induces magnetic torque and attraction on the valve element causing it to rotate within the tubular housing lifting same from the valve seat opening the passageway therethrough and through urethra.
