Abstract

An anti-incontinent prosthesis comprising a support member formable into at least one generally spiral turn for location about the corpus spongiosum. A plurality of inflatable chambers are disposed on the turn and connected to a pump means for applying fluid pressure to said chambers to constrict the urethra.

Claims

1. A prosthesis for controlling urinary incontinence comprising support means including a portion in the form of at least one turn of a spiral, said portion including a wall of generally non-stretchable construction and arranged for disposition about the corpus spongiosum and urethra, plural inflatable chambers located at spaced locations along said portion and means for inflating said chambers with a fluid to constrict said urethra.

2. The prosthesis of claim 1 wherein said means for inflating comprises pump means.

3. The prosthesis of claim 2 additionally comprising valve means coupled to said pump means, said pump means being arranged to provide fluid to said chambers to inflate said chambers, said valve means being arranged to prevent said fluid from returning to said pump means until desired.

4. The prosthesis of claim 1 wherein said support means comprises a strip.

5. The prosthesis of claim 4 wherein said strip is formed of bendable material having a silicone rubber covering.

6. The prosthesis of claim 1 wherein said chambers are interconnected by passage means having a substantially smaller cross sectional area than said chambers.

7. The prosthesis of claim 1 wherein each of said chambers is of partial cylindrical shape.

8. The prosthesis of claim 7 wherein said chambers are interconnected by passage means having a substantially smaller cross sectional area than said chambers.

9. The prosthesis of claim 1 wherein each chamber is formed of a resilient material.

10. The prosthesis of claim 9 wherein said material is silicone rubber.

11. The prosthesis of claim 10 wherein each chamber is reinforced by non-stretchable reinforcing means.

12. The prosthesis of claim 11 wherein said reinforcing means is formed of a mesh.

13. The prosthesis of claim 12 wherein said mesh is formed of a synthetic fiber made by the condensation of dimethyl terephthalate and ethylene glycol.

14. The prosthesis of claim 13 wherein said chambers are interconnected by passage means having a substantially smaller cross sectional area than said chambers.

15. The prosthesis of claim 14 wherein each of said chambers is of partial cylindrical shape.

16. The prosthesis of claim 15 wherein said support means comprises a strip formed of bendable material having a silicone rubber covering.
