Abstract

A urethral prosthesis provides relief of urinary retention and has first and second tubular elements with an interposed bridge segment. A valve can be disposed in the second tubular element to control the flow of urine therethrough.

Claims

1. A urethral prosthesis, comprising:

(a) a tubular element including a distal portion and a closed distal end, the distal portion defining a drainage hole for receiving urine from a bladder of a patient, the tubular element further including a proximal end and a lumen extending from the drainage hole through the tubular element to the proximal end, the tubular element further including an inflation balloon, the tubular element configured to maintain an open channel for fluid flow through a prostatic urethra of the patient when the prosthesis is positioned within the patient;

(b) at least one suture extending from the proximal end of the tubular element, the at least one suture passing through a urinary sphincter of the patient when the prosthesis is positioned within the patient to allow the patient to control the urinary sphincter; and

(c) a non-inflatable element extending from a proximal end of the at least one suture, the element including a proximal end and a distal end and defining a length between the proximal end and the distal end, the distal end of the element defining a width greater than a width of the proximal end of the element.

2. The urethral prosthesis of claim 1, wherein the inflation balloon disposed near the drainage hole.

3. The urethral prosthesis of claim 1, wherein the inflation balloon disposed on the tubular member.

4. The urethral prosthesis of claim 1, wherein the inflation balloon is inflatable over at least a portion of the tubular element.

5. The urethral prosthesis of claim 1, wherein the at least one suture comprises polymeric material.

6. The urethral prosthesis of claim 1, wherein the at least one suture comprises silicone.

7. The urethral prosthesis of claim 1, wherein the at least one suture comprises metal.

8. The urethral prosthesis of claim 1, wherein the at least one suture comprises plastic.

9. The urethral prosthesis of claim 1, wherein the at least one suture comprises rubber.

10. The urethral prosthesis of claim 1, wherein the at least one suture comprises braided filaments.

11. The urethral prosthesis of claim 1, wherein the at least one suture comprises a monofilament.

12. The urethral prosthesis of claim 1, wherein the tubular element comprises a pliable, biocompatible material.

13. The urethral prosthesis of claim 1, wherein the tubular element includes a silicone coating.

14. The urethral prosthesis of claim 1, wherein the tubular element comprises silicone rubber.

15. The urethral prosthesis of claim 1, wherein the tubular element comprises a circular cross section.

16. The urethral prosthesis of claim 1, wherein the tubular element comprises a C-shaped cross section.

17. The urethral prosthesis of claim 1, wherein the tubular element comprises a semi-circular cross section.

18. The urethral prosthesis of claim 1, wherein the element comprises a pliable, biocompatible material.

19. The urethral prosthesis of claim 1, wherein the element includes a silicone coating.

20. The urethral prosthesis of claim 1, wherein the element comprises silicone rubber.

21. The urethral prosthesis of claim 1, wherein at least a portion of the element comprises a tubular shape.

22. The urethral prosthesis of claim 1, wherein the element comprises a circular cross section.

23. The urethral prosthesis of claim 1, wherein the element comprises a C-shaped cross section.

24. The urethral prosthesis of claim 1, wherein the element comprises a semi-circular cross section.

25. The urethral prosthesis of claim 1, further comprising at least one removal suture.

26. The urethral prosthesis of claim 25, wherein the at least one removal suture is connected to the tubular element.

27. The urethral prosthesis of claim 25, wherein the at least one removal suture is connected to the element.

28. The urethral prosthesis of claim 25, wherein the at least one removal suture comprises polymeric material.

29. The urethral prosthesis of claim 25, wherein the at least one removal suture comprises silicone.

30. The urethral prosthesis of claim 25, wherein the at least one removal suture comprises metal.

31. The urethral prosthesis of claim 25, where wherein the at least one removal suture comprises plastic.

32. The urethral prosthesis of claim 25, wherein the at least one removal suture comprises rubber.

33. The urethral prosthesis of claim 25, wherein the at least one removal suture comprises braided filaments.

34. The urethral prosthesis of claim 25, wherein the at least one removal suture comprises a monofilament.

35. The urethral prosthesis of claim 1, wherein the tubular element has a length greater than the length of the element.

36. The urethral prosthesis of claim 1, wherein the distal end of the element has an outer diameter greater than an outer diameter of the proximal end of the element.

37. The urethral prosthesis of claim 1, wherein the element is configured to be disposed within a penile urethra.

38. The urethral prosthesis of claim 1, wherein the element is configured to substantially maintain the width at the distal end and the width at the proximal end during both insertion and while maintained within a urethra.
