Abstract

A sling for supporting the urethra and neck of the bladder to prevent urinary incontinence is disclosed. The sling is designed to provide sufficient support to inhibit the unintended flow of urine, yet stretch in a controlled fashion so that the bladder can be voided at approximate times.

Claims

1. For the treatment of urinary incontinence by supporting the urethra and neck of the bladder, a sling comprising:

a) a support made of a stretchable non-porous material to limit tissue integration into the support;

b) first and second suture anchors positioned at opposite ends of the stretchable support; and

c) sutures cooperating with said suture anchors to fix the stretchable support in place.

2. The sling of claim 1 wherein said material from which said support is made is a synthetic, biocompatible, elastic material.

3. The sling of claim 2 wherein the elasticity of said material approximates that of human tissue.

4. The sling of claim 2 wherein said material is silicone.

5. The sling of claim 2 wherein said material is porous.

6. The sling of claim 2 wherein said material is treated to inhibit infection.

7. The sling of claim 2 wherein said material is treated to inhibit inflammation.

8. The sling of claim 2 wherein said material is treated to promote tissue ingrowth.

9. The sling of claim 2 wherein said material is lubricious.

10. The sling of claim 2 wherein said material is treated to improve lubricity.

11. The sling of claim 1 wherein said support is rectangular in shape.

12. The sling of claim 1 wherein said support is generally oval in shape.

13. The sling of claim 1 further including at least one relief hole through said support.

14. The sling of claim 13 wherein the elasticity of the support is a function of the size of said relief holes.

15. The sling of claim 13 wherein the elasticity of the support is a function of the number of said relief holes.

16. The sling of claim 1 further including a flexible sheath extending laterally across said support, and a string extending within said sheath, said string having a first end coupled to said first suture anchor and a second end coupled to said second suture anchor.

17. The sling of claim 16 wherein said sheath is integral with said support.

18. The sling of claim 16 wherein said sheath is secured to the underside of said support.

19. The sling of claim 16 wherein said string limits how much the sling can stretch.

20. The sling of claim 16 wherein said string is a monofilament.

21. The sling of claim 20 wherein said string is pre-coiled by a heat set operator.

22. The sling of claim 1 wherein said sutures are made of an elastic material.

23. For the treatment of urinary incontinence by supporting the urethra and neck of the bladder, a sling comprising:

(a) a support;

(b) first and second suture anchors positioned at opposite ends of the support; and

(c) stretchable sutures cooperating with said suture anchors to hold the support within a desired range of motion.

24. A device for supporting the urethra and bladder neck to treat urinary incontinence, comprising an elongated, flexible elastic support member having first and second ends, said ends adapted for connection to a portion of the anatomy with the support member spanning the bladder neck.

25. For the treatment of urinary incontinence by supporting the urethra and neck of the bladder, a sling comprising:

(a) a stretchable support including at least one relief hole through said support;

(b) first and second suture anchors positioned at opposite ends of the stretchable support; and

(c) sutures cooperating with said anchors to fix the stretchable support in place.

26. The sling of claim 25 wherein the elasticity of the stretchable support is a function of the size of said relief holes.

27. The sling of claim 25 wherein the elasticity of the stretchable support is a function of the number of said relief holes.

28. The sling of claim 25 further including a flexible sheath extending laterally across said support, and a string extending within said sheath, said sling having a first end coupled to said first suture anchor and a second end coupled to said second suture anchor.

29. The sling of claim 28 wherein said sheath is integral with said support.

30. The sling of claim 28 wherein said sheath is secured to the underside of said support.

31. The sling of claim 28 wherein said string limits how much the sling can stretch.

32. The sling of claim 28 wherein said string is a monofilament.

33. The sling of claim 32 wherein said string is pre-coiled by a heat set operator.
