Abstract

A tissue connecting device is provided. The device comprise an elongate delivery device having a lumen, a proximal end, and a distal end. The distal end is configured to engage tissue and advance the device into tissue. At least one anchor deliverable through a lumen of the elongate delivery device. The distal end of the device may be designed to engage tissue upon rotation of the device about its longitudinal axis.

Claims (23)

1. A tissue anchor assembly, comprising;

a helical tissue anchor capable of piercing tissue through rotation,

a suture coupled to a distal end of the helical tissue anchor and configured to provide that as more force is applied to the helical tissue anchor by the suture, the helical tissue anchor collapses upon itself and provides additional support to tissues in which it is attached;

a tissue support member;

a clamp coupled to the suture to provide tension between the tissue support member and the anchor, and

a releasable elongated delivery device with a distal end configured to releasably engage the anchor, the elongated delivery device including engagement threads that allow rotation of the helical tissue anchor for securement.

2. The assembly of claim 1 , wherein at least a portion of the tissue support member is a mesh slideably coupled to the suture.

3. The assembly of claim 1 , wherein the anchor has a helix geometric configuration.

4. The assembly of claim 1 , wherein the anchor is made of at least one of metal or a polymer.

5. The assembly of claim 1 , wherein at least a portion of the anchor is sufficiently porous to provide for tissue in-growth.

6. The assembly of claim 1 , wherein the anchor includes medicamant delivery to tissue.

7. The assembly of claim 1 , wherein the anchor incorporates at least one of, a healing hormone or a composition that provides a therapeutic response to tissue.

8. The assembly of claim 1 , wherein the suture is at least one of, a monofilament and a braided multifilament.

9. The assembly of claim 1 , wherein the suture is made of a material that is absorbable.

10. The assembly of claim 1 , wherein the suture is configured to deliver a medicament to tissue.

11. The assembly of claim 1 , wherein the suture is porous to promote tissue in-growth.

12. The assembly of claim 1 , wherein at least a portion of the tissue support member is made of mesh.

13. The assembly of claim 12 , wherein the mesh is configured to provide support to at least one of a urethra and bladder.

14. The assembly of claim 12 , wherein the mesh is configured to provide support to a vagina.

15. The assembly of claim 12 , wherein the mesh is woven of a monofilament.

16. The assembly of claim 12 , wherein the mesh is made of a polymer.

17. The assembly of claim 12 , wherein the mesh is configured to deliver a medicament to tissue.

18. The assembly of claim 12 , wherein the medicament is selected from at least one of, estrogen, estrodiol, a substance that promotes tissue in-growth and a substance that provides a therapeutic response to tissue.
