Abstract

An incontinence pessary device for use within a vaginal vault of a woman, the incontinence pessary device comprising a resilient main support body, at least two resilient lateral support bodies, and a suburethral support body. The resilient main support body has a primary plane of orientation that will correspond to the sagittal plane of the woman'"'"'s pelvis when inserted and be at least responsive to forces oriented along the main plane. The at least two resilient lateral support bodies project from a position on the main support body toward generally opposite sides of the main support body in a secondary plane generally perpendicular to the primary plane. Thus, when inserted, the at least two resilient lateral support bodies provide lateral and additional rotational stabilization, being at least responsive to forces oriented along the secondary plane. The suburethral support body has a longitudinal axis of orientation in the primary plane, which forms an obtuse angle to the secondary plane, and has a surface, elongated along the longitudinal axis, for engaging the mucosa and periurethral tissues of the vaginal vault of the woman when placed in position within the woman'"'"'s vaginal vault. The suburethral support body projects from a position on the main support body generally opposite the position of projection for the at least two lateral support bodies.

Claims

1. An incontinence pessary device for use within a vaginal vault of a woman, the incontinence pessary device comprising:

a resilient main support body having a primary plane of orientation and at least responsive to forces oriented along the main plane;

at least two resilient lateral support bodies projecting from a position on the main support body toward generally opposite sides of the main support body in a secondary plane generally perpendicular to the primary plane, the at least two resilient lateral support bodies being at least responsive to forces oriented along the secondary plane; and

a suburethral support body having a longitudinal axis of orientation in the primary plane and forming an obtuse angle to the secondary plane and having a contact surface elongated along the longitudinal axis, for engaging the mucosa and periurethral tissues of the vaginal vault of the woman, the suburethral support body projecting from a position on the main support body generally opposite the position of projection for the at least two lateral support bodies.

2. The invention of claim 1 in which the main support body comprises a polymer.

3. The invention of claim 2 in which the polymer comprises a polymer selected from a list of polymers consisting of:

elastomeric silicone, polyethylene, polypropylene, polyester, polyurethane, poly(vinyl chloride), polyisobutylene, polychloroprene, polybutadiene, and copolymers of this list.

4. The invention of claim 3 in which the at least two lateral support bodies comprises a polymer and the polymer of the at least two lateral support bodies is the same polymer of the main support body.

5. The invention of claim 4 in which the at least two lateral support bodies include imbedded flexible metal rods.

6. The invention of claim 3 in which the suburethral support body comprises a polymer and the polymer of the suburethral support body is the same polymer of the main support body.

7. The invention of claim 6 in which the suburethral support body includes at least one imbedded flexible metal circular ring.

8. The invention of claim 3 in which the main support body includes an imbedded flexible metal circular band.

9. The invention of claim 2 in which the suburethral support body comprises a polymer.

10. The invention of claim 9 in which the polymer of the suburethral support body is the same polymer of the main support body.

11. The invention of claim 9 in which the suburethral support body includes at least one imbedded flexible metal circular ring.

12. The invention of claim 2 in which the main support body includes an imbedded flexible metal circular band.

13. The invention of claim 2 in which the at least two lateral support bodies comprises a polymer.

14. The invention of claim 13 in which the polymer of the at least two lateral support bodies is the same polymer of the main support body.

15. The invention of claim 13 in which the at least two lateral support bodies include imbedded flexible metal rods.

16. The invention of claim 1 in which the suburethral support body includes two lateral prominences laterally positioned to either side of the contact surface and elongate along the longitudinal axis forming a hollow therebetween.

17. The invention of claim 1 in which the suburethral support body further comprises an inner cylinder in fluid communication with an expansion space beneath a distendable membrane on the contact surface of the suburethral support body and expansion means for expanding and retracting the distendable membrane by the movement of a fluid into and out of the expansion space.

18. The invention of claim 17 in which the expansion means comprises an adjustable plunger operably engaging and telescopically slidable within the rigid inner cylinder forming an inner chamber of the rigid inner cylinder for holding the fluid.

19. The invention of claim 18 in which the adjustable plunger is controllable by a ratchet and pawl mechanism between the adjustable plunger and the inner cylinder.

20. The invention of claim 17 in which the expansion means comprises a tube with a valve in fluid communication with the expansion space, the valve adapted to connect to a hand held syringe.

21. The invention of claim 17 in which the rigid inner cylinder further comprises at least one mucous vent through a side wall of the rigid inner cylinder.

22. The invention of claim 17 in which the suburethral support body further comprises an electrode array of at least two electrodes in the distendable membrane on the surface of the suburethral support body for providing electrical stimulation to mucosa, periurethral tissue and urethra of the woman, the at least two electrodes electrically connected to a power source and control circuit for energizing the at least two electrodes.

23. The invention of claim 22 in which the power source and control circuit are carried separately from the remainder of the incontinence pessary device.

24. The invention of claim 22 in which the suburethral support body includes two lateral prominences laterally positioned to either side of the contact surface and elongate along the longitudinal axis forming a hollow therebetween.

25. The invention of claim 17 in which the suburethral support body includes two lateral prominences laterally positioned to either side of the contact surface and elongate along the longitudinal axis forming a hollow therebetween.

26. The invention of claim 1 in which the suburethral support body further comprises an electrode array of at least two electrodes in the surface of the suburethral support body for providing electrical stimulation to mucosa, periurethral tissue and urethra of the woman, the at least two electrodes electrically connected to a power source and control circuit for energizing the at least two electrodes.

27. The invention of claim 26 in which the power source and control circuit are carried separately from the remainder of the incontinence pessary device.

28. The invention of claim 26 in which the suburethral support body includes two lateral prominences laterally positioned to either side of the contact surface and elongate along the longitudinal axis forming a hollow therebetween.

29. The invention of claim 1 in which the main support body includes an imbedded flexible metal circular band.

30. The invention of claim 1 in which the at least two lateral support bodies include imbedded flexible metal rods.

31. The invention of claim 1 in which the suburethral support body includes at least one imbedded flexible metal circular ring.
