CLAIMS
1. A urethral cap for alleviating urinary incontinence, when applied over the meatus ofthe body of a user,
said cap comprising a resilient at least partially deformable cap body having a hand griping portion,
said body defining a chamber there within sized to allow for reciprocal resilient deformation of said cap body to provide a vacuum therein to hold said urethral cap on the body of a user and close the meatus of said body ofthe user,
said cap body defining an encircling flange having a body contacting surface to act as a sealing surface with the body of a user.

2. A urethral cap in accordance with claim 1 and further comprising a sealing material covering said body contacting surface for aiding in preventing fluid flow between the body contacting surface and the body of an individual when said cap is in use.

3. A urethral cap in accordance with claim 1 wherein said encircling flange has an outer diameter of from about 2.3 to about 3.4 centimeters.

4. A urethral cap in accordance with claim 2 wherein said encircling flange has an outer diameter of about 3 centimeters.

5. A urethral cap in accordance with claim 1 wherein said chamber defines a central axis passing from a top of said cap to a bottom of said cap, with said bottom being defined by said encircling flange, said top to bottom having a height of about 2 centimeters.

6. A urethral cap in accordance with claim 1 wherein said cap is integrally formed of a resilient material which allows ease of application to the body of a user by deforming said cap chamber, applying said cap to the user body about the orifice of a urethra and releasing said deforming pressure to define an air pressure difference between said chamber and the atmosphere sufficient to seal said flange to the user and to prevent liquid flow therethrough at normal pressures encountered in urinary fluids expressed by the body, said cap further defining a meatus constricting surface to close said meatus when said cap is applied with said pressure difference acting to position said cap.

7. A urinary cap in accordance with claim 1 wherein said cap is formed of an FDA approved silicone rubber.

8. A urinary cap in accordance with claim 1 carrying a layer ofthe sealing material over said body contacting surface,
and a release strip covering said sealing material.

9. A urethral cap in accordance with claim 8 and further comprising a second layer of sealing material over said release strip and a second release strip overlying said second layer of sealing material.

10. A urethral cap in accordance with claim 2 wherein said sealing material is a lubricant with no adhesive properties.

11. A urethral cap in accordance with claim 2 wherein said sealing material is an adhesive.

12. A urethral cap in accordance with claim 1 wherein said cap conforms to ISO 9000 manufacturing standards.

13. A urethral cap in accordance with claim 12 wherein said cap is packaged in accordance with ISO 9000 manufacturing standards.

14. A urethral cap in accordance with claim 2 wherein said cap is integrally formed of a silicone rubber material compatible with and nonirritating to the skin ofthe body.

15. A urethral cap in accordance with claim 2 wherein said encircling flange has an outer diameter of from about 2.3 to about 3.4 centimeters.

16. A urethral cap in accordance with claim 5 and further comprising a sealing material covering said body contacting surface for aiding in preventing liquid flow between the body contacting surface and the body of an individual when said cap is in use.

17. A urethral cap in accordance with claim 16, wherein said cap provides a generally fustroconical inner surface adjacent said flange body contacting surface to aid in closing said meatus by compression.

18. A method for alleviating urinary incontinence of a user, said method comprising: applying a urethral cap having an internal chamber over a urethra outer body orifice of a user, said cap defining a hand gripping portion and an encircling flange having a body contacting surface area which aids in sealing said urethral cap to the body of a user,
employing air pressure below ambient atmospheric air pressure to maintain said cap in place,
and removing said urethral cap to allow voiding when desired.

19. A method in accordance with the method of claim 18 wherein a sealing material is applied to said body contacting surface before application of said cap to the body orifice of a user,
and said air pressure acts to compress and seal the meatus to urinary flow.

20. A method in accordance with the method of claim 19 wherein said urethral cap is applied by resiliently compressing said cap, contacting said body contacting surface area with the body ofthe user, positioning a central axis of said cap over said urethra outer body orifice, and allowing said cap to resiliently return towards its original configuration.

21. In a method of preventing unwanted urinary flow from the body of a female user, the method comprising:
applying a urethral cap over the orifice ofthe urethra and maintaining said cap in place on the body ofthe user by the use of air pressure to prevent urinary flow beyond said cap.

22. In a method of alleviation of urinary incontinence, wherein a hand applied device is used to prevent unwanted urinary flow, the improvement comprising,
using a hand applied and removable device mounted externally ofthe body to close the meatus ofthe body to urinary flow,
and removing said device from the body to allow the meatus to return to its opened natural state and permit urinary flow when desired.

23. A urethral cap for alleviating urinary incontinence when attached to the body of a user, while minimizing infection ofthe user by avoiding the use of components of said cap passing into or through the urethra of a user,
said cap comprising a hand gripping portion for use in mounting said cap over the urethra external orifice of said body,
said cap having an interior surface and an exterior surface and defining an interior chamber for establishing a pressure differential between said urethral cap and the atmosphere to aid in maintaining said cap in position attached to said body,
a meatus compressing and closure surface, and
an encircling flange having a body contacting surface to act as a sealing surface with the body of a user, said encircling flange being constructed and arranged to surround said urethral external orifice.
