Abstract

A soft tissue repair system is provided for covering or filling openings in the annulus of an intervertebral disc. The soft tissue repair system uses a single plug or a combination of a first plug and a second plug. The second plug is a flowable plug such as an adhesive material or a material that hardens to a flexible plug material. Each plug is configured to close the opening in the annulus and can be positioned within the opening, over the opening at the exterior surface or over the opening at the interior surface. The plug can also be combined with a clamping mechanism that engages the annulus to secure the plug in the opening.

First claim

What is claimed is:

1 . A soft tissue repair system for an intervertebral disc having an annulus and a nucleus pulposus, the system comprising:
a first plug configured to close an opening that passes through the annulus from an exterior surface of the annulus to an interior surface of the annulus by being positioned within the opening, the first plug comprising a collapsible cage having a pair of opposing ends and a plurality of arms extending between the opposing ends and fixedly secured thereto, the collapsible cage configured to collapse and to expand to fill the opening in the annulus; and a second plug separate from the first plug and configured to close the opening, the second plug comprising a flowable plug material, the second plug is disposed within the opposing ends and the plurality of arms of the collapsible cage, the second plug emerging from the collapsible cage as it is collapsed.

2 . The soft tissue repair system of claim 1 , wherein each arm of the plurality of arms comprises a spike disposed along its length and extending outward from the collapsible cage, each spike configured to penetrate the annulus when the collapsible cage is collapsed.

3 . The soft tissue repair system of claim 2 , wherein opposite each spike, across the arm, a notch extends inward of the arm.

4 . The soft tissue repair system of claim 1 , wherein each of the pair of opposing ends is configured as a disc.

5 . The soft tissue repair system of claim 1 , wherein each of the pair of opposing ends includes a central hole passing completely therethrough.

6 . The soft tissue repair system of claim 1 , wherein each of the pair of opposing ends has a diameter that is less than the size of the annulus that is to be repaired.

7 . The soft tissue repair system of claim 1 , wherein the plurality of arms is arranged as opposing pairs.

8 . The soft tissue repair system of claim 1 , wherein the plurality of arms includes at least one having a generally flat arm with opposing thin edges and opposing flat faces.

9 . The soft tissue repair system of claim 8 , wherein the plurality of arms is positioned so that one of the thin edges runs along the outside of the first plug.

10 . The soft tissue repair system of claim 1 , wherein the first plug is compressed by drawing the two opposing ends together.

11 . A soft tissue repair system for an intervertebral disc having an annulus and a nucleus pulposus, the system comprising:
a plug configured to close an opening that passes through the annulus from an exterior surface of the annulus to an interior surface of the annulus by being positioned within the opening, the first plug comprising a collapsible cage having a pair of opposing ends and a plurality of arms extending between the opposing ends and fixedly secured thereto, the collapsible cage configured to collapse and to expand to fill the opening in the annulus.

12 . The soft tissue repair system of claim 11 , wherein each arm of the plurality of arms comprises a spike disposed along its length and extending outward from the collapsible cage, each spike configured to penetrate the annulus when the collapsible cage is collapsed.

13 . The soft tissue repair system of claim 12 , wherein opposite each spike, across the arm, a notch extends inward of the arm.

14 . The soft tissue repair system of claim 11 , wherein each of the pair of opposing ends is configured as a disc.

15 . The soft tissue repair system of claim 11 , wherein each of the pair of opposing ends includes a central hole passing completely therethrough.

16 . The soft tissue repair system of claim 11 , wherein each of the pair of opposing ends has a diameter that is less than the size of the annulus that is to be repaired.

17 . The soft tissue repair system of claim 11 , wherein the plurality of arms is arranged as opposing pairs.

18 . The soft tissue repair system of claim 11 , wherein the plurality of arms includes at least one having a generally flat arm with opposing thin edges and opposing flat faces.

19 . The soft tissue repair system of claim 18 , wherein the plurality of arms is positioned so that one of the thin edges runs along the outside of the first plug.

20 . The soft tissue repair system of claim 11 , wherein the first plug is compressed by drawing the two opposing ends together.
