Proximity intraurethral valve using permanent magnet check
First Claim
1. An intraurethral magnetic valve for insertion into the urethra of a person'"'"'s body comprising in combination a tubular housing, a valve element within said housing, and a valve seat sealingly engaged by said valve element, said tubular housing is non-magnetic having an internal recessed area adjacent one end thereof, a plurality of spaced fingers extending inwardly from said tubular housing in spaced relation to said recessed area, said valve seat in annular registration with said recessed area in said tubular housing, said valve element comprising an encapsulated permanent magnet magnetized along a center line axis, a nonferromagnetic means for encapsulation spacing said permanent magnet, means for spacing said permanent magnet in respect to said valve seat, said element being normally attracted to said valve seat occluding and sealing same, means for opening said valve comprising a source of magnetic attraction in spaced relation to said person'"'"'s body, said magnetic attraction selectively imposes a magnetic field on said valve element pivoting same away from said sealing relation with said valve seat, and means for inserting said magnetic valve assembly within the urethra of said person'"'"'s body.

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.

- 6. A intraurethral magnetic valve for insertion into the urethra of a person comprising in combination a tubular housing, a hinge valve element within said housing, a valve seat sealingly engaged by said valve element, said tubular housing is non-magnetic having an internal recessed area adjacent an upstream end thereof, said valve seat positioned for annular sealing registration with said recessed area, a plurality of annularly spaced flanges extending inwardly from said tubular housing and spaced in opposing relation to said valve seat, said valve element comprising an enclosed permanent magnet magnetized along a center line axis, a mounting hinge integral to said enclosed magnet and a pivot pin engaging said hinge valve element within said tubular housing, means for spacing said permanent magnet in relation to said valve seat, means for opening said valve by a source of magnetic attraction in spaced relation to said person, and means for securing said magnetic valve within the urethra of said person.
- 10. A magnetic valve comprising in combination a tubular housing, a valve element within said housing, and a valve seat adjacent one end thereof, said valve seat sealingly engaged by said valve element, said tubular housing is non-magnetic, a plurality of projections extending inwardly from said tubular housing in spaced relation to said valve seat, and said valve seat in annular registration with said tubular housing, said valve element comprising an encapsulated permanent magnet magnetized along a center line axis, a nonferromagnetic means for encapsulation of said permanent magnet, means for spacing said permanent magnet in respect to said valve seat, said valve element being normally attracted to said valve seat occluding and sealing same, means for opening said magnetic valve by a source of magnetic attraction positioned in spaced relation thereto, said source of said magnetic attractive selectively imposes a magnetic field on said valve element pivoting same away from said valve seat, opening a passage through said magnetic valve.
- 14. A magnetic valve comprising in combination a tubular housing, a hinge valve element within said housing, a valve seat engaged by said valve element, said tubular housing is non-magnetic, said valve seat positioned for annular sealing registration within said tubular housing, means for selectively retaining said valve element within said tubular housing, said valve element comprises an encapsulated permanent magnet magnetized along a center line axis, a mounting hinge integral to said encapsulated permanent magnet and a pivot pin engaging said mounting hinge and said tubular housing, means for spacing said permanent magnet in relation to said valve seat, means for opening said valve by a source of magnetic attraction located in spaced relation to said tubular housing.
