Abstract

The present invention relates to a valve (1) intended for positioning in the urethra (2) or similar of a patient in the upper part (2A) of the urethra, which exhibits means for emptying the patient'"'"'s urine bladder (5) or similar through the valve (1). The valve (1) is so arranged as to be positioned in the urethra (2), etc., and to be withdrawn from it with the help of a tool capable of being accomodated in the urethra, etc., and activated from the outside (10) of the patient'"'"'s body, and the valve (1) is adjustable from the outside (10) of the patient'"'"'s body for the purpose of achieving emptying of the urine bladder (5), etc. The primary technical objectives are that the construction must be leakproof, simple to open and close by the patient, tolerated by the body, and free from side-effects. The valve must be adapted to suit the sex, age and body weight of the patient and the size of the urethra.

Claims

1. A valve adapted to be positionable into an upper part of a urethra, said valve for emptying a patient'"'"'s urine collected within his bladder, comprising:

a tubular valve housing having an upper, lower, and central part and a central channel therein;

a valve body formed by a permanent magnet accomodated with the upper portion of the valve;

a stop situated at the upper part of the valve housing;

a valve seat situated below said valve body, said central part having a plurality of drainage holes extending perpendicularly through said tubular housing, said drainage holes located in the area between the stop and the valve seat, said central channel of the valve housing in communication with said drainage holes, said central channel and said drainage holes emptying urine through the valve while in an inserted position, and sealing the valve with the valve body in its extended position, the valve arrangeable so as to be positionable within the urethra and withdrawable from it with the help of a tool capable of accommodation in the urethra, said valve arranged and constructed to accommodate a manual activator introducible from the outside of the patient'"'"'s body through the urethra up to the valve;

a plurality of holding devices securing the valve in the urethra producing a sealing and retaining effect around a periphery of the valve, said devices formed from a plurality of self-expanding bodies, the valve adjustable from the outside of the patient'"'"'s body for emptying of the urine bladder, and said valve seat accommodated internally in the valve housing and interactive with the outward-facing end of the valve body in the closed position.

2. The valve of claim 1, wherein the holding devices are adopted to be filled with a liquid.

3. The valve of claim 2, wherein said holding devices are formed by a common rubber balloon having a common filling orifice for filling said liquid therein.

4. The valve of claim 2, wherein said valve is so arranged as to be opened and/or closed by means of electrical impulses through a remote control.

5. The valve of with claim 3, wherein said valve is so arranged as to be opened and/or closed by means of electrical impulses through a remote control.

6. The valve of claim 1, wherein said holding devices are formed by a compressible material.

7. The valve of with claim 6, wherein said valve is so arranged as to be opened and/or closed by means of electrical impulses through a remote control.

8. The valve of claim 6, wherein the valve seat is constructed as a sleeve, and a seal is provided to interact with the valve body between the valve body and said valve seat.

9. The valve of claim 8, wherein said valve is so arranged as to be opened and/or closed by means of electrical impulses through a remote control.

10. Valve in accordance with claim 1, characterized in that the valve (101) is so arranged as to be opened and/or closed by means of electrical impulses through so-called remote control.

11. The valve of claim 1, wherein said holding devices are fillable with a suitable fluid at a pressure tolerable by the patient'"'"'s mucous membranes, and wherein the valve replaceable at regular intervals, arrangeable so as to be capable of automatic ejection from the urethra due to a pressure differential building up.

12. The valve of with claim 1, wherein said valve is so arranged as to be opened and/or closed by means of electrical impulses through a remote control.

13. A valve for implantation within the urethra of a body of a patient at the juncture of the urethra and the bladder, for controlling the flow of urine through the urethra, comprising:

an axially elongated hollow tubular housing of substantially cylindrical configuration having an internal cavity, an upper and inward-facing end, a lower and outward-facing end, and a central part therebetween, said central part including a plurality of radially arranged drainage holes for communicating urine from said bladder, through said holes, and into said internal cavity;

a valve stop inserted within said upper end;

a movable valve body disposed at said upper end of said tubular housing formed by a permanent magnet and disposed within said housing below and stop;

a valve seat disposed within said housing, below said drainage holes, said valve body movable between said seat and said stop, wherein when said valve body is in resting contact against said seat, said drainage holes are closed, said seat formed by a permanent magnet and having an axially disposed central channel in communication with said cavity of said housing, a lower end of said seat having an upwardly converging throat for removably coupling an insertion and removal instrument therewith;

a plurality of holding devices in the form of self-expending bodies located on an exterior of said housing at axially spaced locations generally between said seat and said lower end,

wherein said permanent magnets of said valve body and seat are selectively balanced so as to create a near equilibrium condition of magnetic attraction between said seat and valve body where said valve body is magnetically attracted downwardly against said seat with a deminimus attraction force, thereby closing said drainage holes, wherein direct manipulation against said valve body with one of a wire, catheter and probe from outside said body causes said valve body to readily overcome said balanced magnetic attraction force so as to unseat and open, thereby allowing passage of urine from said bladder and into said drainage holes of said valve.
