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.

Claims

1. An implant for use in treating a pelvic floor condition in a patient, the implant comprising:

a mesh having a first longitudinal edge and a second longitudinal edge and at least one longitudinal surface and being sized and shaped to support one or more of a patient'"'"'s urethra, bladderneck, and pelvic organ;

a tissue anchor coupled with a proximal end of the mesh, the tissue anchor being configured to penetrate a tissue of the patient; and

a resilient strengthening member woven into the mesh and spaced apart from the tissue anchor,

the resilient strengthening member having a first end and a second end, the resilient strengthening member extending across a transverse width of the mesh, the first end of the resilient strengthening member protruding beyond the first longitudinal edge of the mesh and the second end of the resilient strengthening member protruding beyond the second longitudinal edge of the mesh.

2. The implant of claim 1, wherein the resilient strengthening member is attached to the mesh at a plurality of points.

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

4. The implant of claim 3, wherein the rigid member is disposed substantially perpendicular to the first longitudinal edge.

5. The implant of claim 1, wherein the resilient strengthening member is disposed in an end region of the mesh.

6. The implant of claim 5, wherein the resilient strengthening member is distally disposed at about 25% of a way from the proximal end of the mesh to a center of the mesh.

7. The implant of claim 5, wherein the resilient strengthening member is spaced away from a center region of the mesh, the center region of the mesh being adapted to be adjacent to one or more of the patient'"'"'s urethra, bladderneck, and pelvic organ.

8. The implant of claim 1, wherein the resilient strengthening member includes plastic or metal.

9. The implant of claim 1, further comprising a plurality of resilient strengthening members.

10. The implant of claim 9, further comprising a first plurality of resilient strengthening members disposed in a first end region of the mesh and a second plurality of resilient strengthening members disposed in a second end region of the mesh.

11. An implant for use in treating a pelvic floor condition in a patient, the implant comprising:

a mesh configured to support one or more of a patient'"'"'s urethra, bladderneck, and pelvic organ, the mesh having a first longitudinal edge, a second longitudinal edge, a first end region, a second end region and a center region;

a first plurality of stiffening members woven into the mesh and disposed in the first end region of the mesh; and

a second plurality of stiffening members woven into the mesh and disposed in the second end region of the mesh, the center region of the mesh being devoid of stiffening members,

each stiffening member of the first plurality of stiffening members and the second plurality of stiffening members extending across a transverse width of the mesh and having a first end and a second end, the first end protruding beyond the first longitudinal edge of the mesh and the second end protruding beyond the second longitudinal edge of the mesh.

12. The implant of claim 11, wherein the first plurality of stiffening members are longitudinally arrayed in the first end region of the mesh.

13. The implant of claim 11, wherein the second plurality of stiffening members are longitudinally arrayed in the second end region of the mesh.

14. The implant of claim 11, wherein the stiffening members of the first plurality of stiffening members and the second plurality of stiffening members are perpendicular with the first longitudinal edge and perpendicular with the second longitudinal edge.

15. The implant of claim 11, wherein first ends and the second ends of the first plurality of stiffening members are configured to penetrate a flesh of a patient and to stimulate scar tissue ingrowth at the first end region.

16. The implant of claim 11, wherein first ends and the second ends of the second plurality of stiffening members are configured to penetrate a flesh of a patient and to stimulate scar tissue ingrowth at the second end region.
