Abstract

A pubic bone-mounted urethra stabilization and support system and method therefor for the long term cure of recurrent female urinary incontinence. The system comprises, a pair of anchors affixed to the posterior/inferior pubic bone, sutures attach to the anchors and a mesh sling passing behind and about the urethra and the adjacent endopelvic fascia and having ends attached to the anchors by the anchor-mounted sutures. The method includes the steps of accessing said urethra with the endopelvic fascia therebehind and the pubic bone, properly locating and attaching the anchors to the pubic bone, properly locating the sling about the urethra and adjacent endopubic fascia and suturing and tensioning the ends of the sling to the anchors, causing said sling to restore, support and stabilize functional urethral continence anatomy and prevent urethral descent under intraabdominal pressure.

Claims

1. A method of treating urinary incontinence in a patient comprising:

preparing said patient for surgery;

creating an incision allowing access to the urethra;

introducing a mesh material through said incision and moving said mesh to a position that traverses the urethra;

adjusting the position and tension of said mesh material relative to said urethra through manipulation of at least one suture interlaced within a weave of said mesh material;

securing said mesh material into place in a manner to effectively treat the urinary incontinence; and

,

closing said incision.

2. A method according to claim 1, wherein said incision is created in the vagina of a female patient.

3. A method according to claim 1, wherein said suture is interlaced into said mesh material just prior to the adjusting of the position and tension of the mesh material.

4. A method according to claim 1, wherein the adjusting of the position and tension of the mesh material is performed by placing upward tension on said mesh material.

5. A method according to claim 1, wherein the manipulation of at least one suture is performed with a suture that is interlaced along substantially the length of one side of said mesh material.

6. A method according to claim 1, wherein the securing of said mesh material includes the manipulation of sutures located proximal to the urethra and distal from ends of the mesh material.

7. A method according to claim 1, wherein the securing of said mesh material includes connecting ends of said mesh material to bone anchors located in a pubic bone of said patient.

8. A method of treating urinary incontinence in a patient comprising:

identifying a region on the patient for making an incision;

creating an incision allowing access to the urethra;

observing the tissue revealed by said incision,

introducing a mesh material through said incision and moving said mesh to a position that traverses the urethra;

manipulating said mesh material using at least one suture interlaced within said mesh material until opposite ends of said mesh material extend upwardly toward an abdomen of said patient;

checking the condition of said urethra in order to confirm proper manipulation of said mesh material; and

,

repairing said incision.

9. A method according to claim 8, wherein the introduction of said mesh material is performed through the vagina of a female patient.

10. A method according to claim 8, wherein the manipulation of said mesh material is performed through the abdomen of said patient.

11. A method according to claim 8, wherein said suture is interlaced into said mesh material just prior to the manipulation of the mesh material.

12. A method according to claim 8, wherein the manipulating of said mesh material is performed by placing upward tension on said mesh material.

13. A method according to claim 8, wherein the manipulation of said mesh material using at least one suture is performed with a suture that is interlaced along substantially the length of one side of said mesh material.

14. A method according to claim 8, wherein the securing of said mesh material includes the manipulation of sutures located proximal to the urethra and distal from ends of the mesh material.

15. A method according to claim 8, wherein the checking of the condition of the urethra includes cystoscopic observation of the urethra.

16. A method of treating urinary incontinence in a patient comprising:

identifying a region on a patient for performing surgery,

creating an incision allowing access to the urethra;

introducing a mesh material through said incision and moving said mesh to a position that traverses the urethra;

observing the mesh material at said position; and

,

adjusting the position of said mesh material relative to said urethra using a suture that is attached to said mesh material in a manner so as to minimize undesirable cinching of said mesh material during permanent placement of said mesh material in said patient.

17. A method according to claim 16, wherein said incision is created in the vagina of a female patient.

18. A method according to claim 16, wherein the adjusting of the position of said mesh material is performed using a suture that is interlaced into said mesh material.

19. A method according to claim 18, wherein said suture is interlaced into said mesh material just prior to the adjusting of the position of said the mesh material.

20. A method according to claim 18, wherein the adjusting of the position of said mesh material is performed using a suture that is interlaced along substantially the length of one side of said mesh material.

21. A method according to claim 18, wherein said suture is interlaced into said mesh material just prior to the adjusting of the position of said the mesh material.

22. A method of treating urinary incontinence in a patient comprising:

identifying a patient suffering from urinary incontinence;

identifying a region on said patient for performing surgery;

creating an incision allowing access to a urethra;

introducing a mesh material through said incision and moving said mesh to a position that traverses the urethra; and

,

controlling tension of said mesh material relative to the urethra through manipulation of sutures that are attached to said mesh material at locations spaced from each distal end of said mesh material and on both sides of a central region of said mesh material; and

,

evaluating the state of said mesh material after controlling the tension.

23. A method as set forth in claim 22, wherein the controlling of tension is performed using permanent sutures.

24. A method as set forth in claim 22, wherein the creating of said incision is performed through the vagina of a female patient.

25. A method as set forth in claim 22, wherein the introducing of a mesh material is performed through the abdomen.

26. A method as set forth in claim 22, wherein the evaluating of the state of said mesh material is performed using cystoscopy.

27. A method as set forth in claim 22, wherein the controlling of the tension is performed so as to secure the mesh material relative to said urethra.

28. A method of treating urinary incontinence in a patient comprising:

identifying a patient suffering from urinary incontinence;

exposing a urethra of said patient;

inserting a urethral support material into said patient;

manipulating said urethral support until said urethral support is located beneath said urethra at a position most effective for treating the incontinence; and

,

ensuring said urethral support is located at a position most effective for treating the incontinence by controlling the tension of regions of said urethral support that are in near proximity to said urethra; and

,

closing the exposure to said urethra.

29. A method as set forth in claim 28, wherein the ensuring of urethral support is performed using sutures.
