Abstract

Disclosed are reinforced meshes for retropubic implants for treatment of urinary incontinence and/or pelvic floor disorders and related uses, devices, and methods. In certain embodiments, implants have various resilient strengthening members added to a retropubic support mesh.

First claim

What is claimed is:

1. An implant for use in treating a pelvic floor condition in a patient, the implant comprising:
a mesh including an a central region having a first longitudinal edge, and a second longitudinal edge, the mesh being sized and shaped to support one or more of a patient's urethra, bladderneck, and pelvic organ, the mesh including a first extended portion extending laterally from the first longitudinal edge, and a second extended portion extending laterally from the first longitudinal edge, the second extended portion being disposed a distance away from the first extended portion along the first longitudinal edge;
a first resilient strengthening member disposed within or on the central region and protruding beyond the first longitudinal edge and into the first extended portion; and
a second resilient strengthening member disposed within or on the central region and protruding beyond the first longitudinal edge and into the second extended portion.

2. The implant of claim 1 , wherein the first resilient strengthening member includes a strengthening knot disposed within or on the central region.

3. The implant of claim 1 , wherein the first resilient strengthening member is a rigid member having a portion adapted to penetrate a tissue of a patient.

4. The implant of claim 3 , wherein the rigid member is oblong.

5. The implant of claim 4 , wherein the rigid member is disposed obliquely with respect to the first longitudinal edge.

6. The implant of claim 4 , wherein the rigid member is disposed substantially perpendicular to the first longitudinal edge.

7. The implant of claim 4 , wherein the rigid member is disposed substantially parallel to the first longitudinal edge.

8. The implant of claim 1 , wherein the first extended portion extends from the first longitudinal edge at an end portion of the central region, and the second extended portion extends from the first longitudinal edge at the end portion of the central region.

9. The implant of claim 1 , wherein the mesh is configured in an irregular shape for pelvic organ support.

10. The implant of claim 1 , wherein an end region of the central region is configured in an irregular shape for securing to a location within the patient.

11. The implant of claim 1 , further comprising:
a third extended portion laterally extending from the second longitudinal edge; and
a fourth extended portion laterally extending from the second longitudinal edge, the fourth extended portion being disposed a distance away from the third extended portion along the second longitudinal edge.

12. The implant of claim 11 , further comprising:
a third resilient strengthening member extending from the central region and into the third extended portion.

13. The implant of claim 11 , wherein the third extended portion extends from the second longitudinal edge at an end portion of the central region, and the fourth extended portion extends from the second longitudinal edge at the end portion of the central region.

14. The implant of claim 1 , wherein the first resilient strengthening member is spaced away from a middle portion of the center region of the mesh, the middle portion being adapted to be adjacent to one or more of the patient's urethra, bladderneck, and pelvic organ.

15. The implant of claim 1 , wherein the first resilient strengthening member has plastic or metal.

16. An implant for use in treating a pelvic floor condition in a patient, the implant comprising:
a mesh including an a central region having a first longitudinal edge, and a second longitudinal edge, the mesh being sized and shaped to support one or more of a patient's urethra, bladderneck, and pelvic organ,
the mesh including a plurality of first extended portions extending laterally from the first longitudinal edge at a first end portion of the central region, and a plurality of second extended portions extending laterally from the second longitudinal edge at the first end portion of the central region,
the mesh including a plurality of third extended portions extending laterally from the first longitudinal edge at a second end portion of the central region, and a plurality of fourth extended portions extending laterally from the second longitudinal edge at the second end portion of the central region; and
a plurality of resilient strengthening members disposed on or within the mesh, at least one of the plurality of resilient strengthening members extending from the central region into one of the first extended portions.

17. An implant for use in treating a pelvic floor condition in a patient, the implant comprising:
a mesh including an a central region having a first longitudinal edge, and a second longitudinal edge, the mesh being sized and shaped to support one or more of a patient's urethra, bladderneck, and pelvic organ,
the mesh including a plurality of first extended portions extending laterally from the first longitudinal edge at a first end portion of the central region, and a plurality of second extended portions extending laterally from the second longitudinal edge at the first end portion of the central region,
the mesh including a plurality of third extended portions extending laterally from the first longitudinal edge at a second end portion of the central region, and a plurality of fourth extended portions extending laterally from the second longitudinal edge at the second end portion of the central region; and
a plurality of resilient strengthening members disposed on or within the mesh, the plurality of resilient strengthening members including knots and fibers.
