Abstract

This disclosure concerns suburethral and pelvic support structures which utilize tissue soldering materials instead of, or in addition to, traditional tissue anchors and suture knots. It further concerns methods of treating patients that includes implanting these structures and activating the tissue soldering materials to attach the structures to a tissue in the body of the patient.

First claim

What is claimed is:

1. A system for treating a patient, comprising:
an implantable mesh including a longitudinal axis extending between a first end portion and a second end portion of the mesh, the implantable mesh having a first side edge and a second side edge opposite the first side edge; and
a bioabsorbable suture including a tissue soldering material, the suture being coupled to the mesh and extending substantially linearly and parallel to the first side edge, the suture extending from the first end portion to the second end portion, the suture configured to be in a first state and in a second state, different than the first state, the second state being activated in response to contact or exposure to a stimulus thereby causing the suture to adhere to a bodily tissue of the patient the tissue soldering material includes a non-uniform coating that forms a texture configured to provide mechanical attachment to bodily tissue.

2. The system of claim 1 , wherein the coating is on a surface of the suture.

3. The system of claim 1 , wherein the tissue soldering material includes a microsphere.

4. The system of claim 3 , wherein the microsphere is embedded in the suture.

5. The system of claim 1 wherein the suture is an extruded tissue soldering material.

6. The system of claim 1 , further comprising an energy source.

7. The system of claim 6 , wherein the energy source is one of an LED light, a laser, a radiofrequency electrode.

8. The system of claim 6 , wherein the energy source is insertable into a body of the patient.

9. The system of claim 8 , wherein the energy source is disposed within or on a distal end of a device selected from the group consisting of a clamp, grasper, dissector, and a forceps, wherein the device is sized to be at least partially inserted into the body of a patient.

10. The system of claim 8 , wherein the energy source is disposed within a suture capture device.

11. The system of claim 1 , wherein the mesh includes a first side portion and a second side portion, the suture extends along the first side portion and the second side portion of the mesh.

12. The system of claim 1 , wherein the suture extends substantially parallel to the longitudinal axis.

13. A system for treating a patient, comprising:
an implantable mesh including a longitudinal axis extending between a first end portion and a second end portion of the mesh; and
a bioabsorbable suture including a tissue soldering material, the suture being coupled to the mesh, the suture extending substantially linearly from the first end portion to the second end portion, the suture configured to be in a first state and in a second state, different than the first state, the second state being activated in response to contact or exposure to a stimulus such that the suture adheres to a bodily tissue of the patient, the tissue soldering material includes a non-uniform coating that forms a texture configured to help provide mechanical attachment to bodily tissue;
a device including an energy source.

14. The system of claim 13 , wherein the coating is on a surface of the suture.

15. The system of claim 13 , wherein the tissue soldering material includes a microsphere.

16. The system of claim 15 , wherein the microsphere is embedded in the suture.

17. The system of claim 13 wherein the suture is an extruded tissue soldering material.

18. The system of claim 13 , wherein the mesh includes a first side portion and a second side portion, the suture extends along the first side portion and the second side portion of the mesh.

19. The system of claim 13 , wherein the suture extends substantially parallel to the longitudinal axis.

20. The system of claim 13 , wherein the coating includes a first portion and a second portion, the first portion being thinner than the second portion.
