Abstract

A female anti-incontinence device is described which includes two flexible discs attached to a flexible stem. The device is inserted into the urethra so that the larger disc occludes the bladder neck during sudden tensing of the abdominal muscles, while the smaller disc remains outside the urethra and prevents migration of the device into the bladder. The device is compact, easy to use, and, since it contains no moving parts, grooves or chambers, there is minimal chance of bacterial colonization and urinary tract infection.

Claims

1. A removable device for preventing involuntary urination in female patients, comprising:

a flexible stem having a first end and a second end;

a first flexible disc having a perimeter, a first face and a second face, said first face of said first disc attached to said first end of said stem;

a second flexible disc having a perimeter, a first face and a second face, said first face of said second disc attached to said second end of said stem; and

a projection attached to the second face of at least one of said discs.

2. The device of claim 1, wherein a string is attached to said projection.

3. The device of claim 2, wherein said string is longitudinally embedded within said stem and said projection, whereby said string extends beyond said projection.

4. The device of claim 1, wherein said projection is continuous with said stem.

5. The device of claim 1, wherein a projection is attached to the second face of each of said first and second discs.

6. The device of claim 4, wherein a string is attached to each of said projections.

7. The device of claim 1, wherein said device is made of a flexible, biocompatible material.

8. The device of claim 7, wherein said material is resistant to degradation by urine.

9. The device of claim 7, wherein said biocompatible material is an elastic polymer.

10. The device of claim 9, wherein said polymer is Kraton G, silicone or polyvinylchloride.

11. The device of claim 7, wherein said stem is more flexible along its lateral axis than along its longitudinal axis.

12. The device of claim 1, wherein said first disc is greater in diameter than said second disc.

13. The device of claim 1, wherein the diameter of said first disc is between about 1.0 cm and about 2.0 cm.

14. The device of claim 13, wherein the diameter of said first disc is 1.5 cm.

15. The device of claim 1, wherein the diameter of said second disc is between about 0.5 cm and about 1.5 cm.

16. The device of claim 15, wherein the diameter of said second disc is 1.0 cm.

17. The device of claim 1, wherein said discs are attached to said stem at their centers.

18. The device of claim 1, wherein said stem joins said discs at right angles.

19. The device of claim 1, wherein the length of said stem is between about three and about six centimeters.

20. The device of claim 1, wherein the diameter of said stem is about 0.4 cm.

21. A method of preventing incontinence in female patients, comprising:

inserting an anti-incontinence device into the urethra of said patient so as to form a seal to occlude the bladder neck of said patient, said device comprising;

a flexible stern having a first end and a second end;

a first flexible disc having a perimeter, a first face and a second face, said first race of said first disc attached to said first end of said stem;

a second flexible disc having a perimeter, a first face and a second face, said first face of said second disc attached to said second end of said stem; and

a projection attached to the second face of at least one of said discs.

22. The method of claim 21, further comprising the step of removing said device prior to voiding of urine.

23. The method of claim 22, wherein said device additionally comprises a string attached to one of said projections, and wherein the removing step comprises pulling on said.

24. The method of claim 23, wherein said device comprises a projection on each of said discs and a string attached to each of said projections, and wherein the method additionally comprises cutting one of said strings prior to the inserting step.
