Disk repair structures with anchors

1 . An implant for repairing damage to an anulus of an intervertebral disk, the implant comprising:

an first anchor part, adapted to anchor the implant to a first vertebra from within the intervertebral disk space;

a second structure part with a first end and a second end attached to the first anchor part; and

a third patch part that connects with the second end of the second structure part, adapted to patch the damage to the anulus.

2 . The implant of claim 1 wherein the first anchor part is a bone anchor.

3 . The implant of claim 2 wherein the bone anchor is made of a material selected from the group consisting of nitinol, titanium, stainless steel and a resorbable material.

4 . The implant of claim 1 wherein the second structure part has a conical shape with a narrow end and an open end.

5 . The implant of claim 4 wherein the second structure part comprises a plurality of wires.

6 . The implant of claim 1 wherein the second structure part is made of a material selected from the group consisting of nitinol, titanium, and stainless steel.

7 . The implant of claim 4 wherein the second structure part comprises a wire mesh.

8 . The implant of claim 1 wherein two such implants are used within the same intervertebral disk space, a first implant anchored by its first anchor part in a first vertebrae and a second implant anchored by its first anchor part in a second vertebrae.

9 . The implant of claim 4 wherein the second structure part comprises a plurality of wires wound as a spiral.

10 . The implant of claim 9 wherein the second structure part spiral can be shortened from a longer length to accommodate different the anatomy of the intervertebral disk space.

11 . The implant of claim 1 wherein the third patch part is made of scarring agents selected from the group consisting of wire mesh, plastic mesh, inert synthetic biocompatible materials, and structural filaments.

12 . The implant of claim 1 wherein the third patch part is placed over a hydrogel plug encased in a constraining jacket.

13 . The implant of claim 12 wherein the hydrogel plug contains therapeutic agents.

14 . An implant for repairing intervertebral disks, the implant comprising:

a bone anchor adapted to engage a vertebra within the intervertebral disk space;

a flexible wire structure having a first end and a second end, the first end connected with the bone anchor; and

an anulus patch that connects with the second end of the flexible wire structure, adapted to repair damage or injury to the anulus, while promoting healing.

15 . The implant of claim 14 wherein the anulus patch is made of a scarring agent selected from the group consisting of plastic mesh, wire mesh, inert synthetic biocompatible materials, and structural filaments.

16 . The implant of claim 14 wherein the anulus patch is placed over a hydrogel plug encased in a constraining jacket.

17 . The implant of claim 16 wherein the hydrogel plug contains therapeutic agents.

18 . The implant of claim 1 wherein the size of the second structure part can be adjusted to accommodate the anatomy of an intervertebral disk space.

19 . A method for repairing a defect in an anulus of an intervertebral disk comprising:

making a surgical incision to expose the defect in the anulus;

inserting a cannula adjacent to the defect;

excising herniated disk tissue if necessary;

positioning an implant in the cannula;

urging the implant through the cannula and into the intervertebral disk space;

anchoring the implant to a vertebra within the intervertebral disk space; and

positioning a patch to seal the damaged site of the anulus;

securing the patch to the anulus.

20 . The method of claim 19 wherein the implant has an anchor means at one end and is positioned in the cannula so that the anchor means enters the damaged site first.
