Abstract

A tissue repair has at least two attachment points for a suture to create a broad area of contact between tissue in bone. When two anchor points are used, the suture extends between and is attached to the two attachment points to create a suture band. When two on more attachment points are used, a first anchor point in the bone has one or more loops. The first anchor point is preferably located on a medial location at the repair site when performing rotator cuff repair. For other types of repair procedures, the first anchor point is different and located as required. The loop or loops are passed through the soft tissue at points spaced from one another. The loop or loops are then captured and secured at anchor points laterally during rotator cuff repair and spaced from the first anchor point and from one another. When complete, the loop or loops are in the form of a “V” and a large area of contact between the soft tissue and bone is established. When more than two loops are used, each loop extends from the first attachment point to another attachment point.

Claims

1. A tissue repair comprising

a first attachment point secured in bone, at least one loop attached to and extending from said first attachment point,

a second attachment point in the bone spaced from said first attachment point,

said at least one loop passing through tissue and secured to said second attachment point.

2. The tissue repair of claim 1, further comprising

a third attachment point spaced from said first and second attachment points,

said at least one loop passing through tissue and secured to said third attachment point.

3. The tissue repair of claim 2, wherein

said second and third attachment points comprise compression anchors.

4. The tissue repair of claim 2, wherein

said second and third attachment points comprise a sleeve and plug.

5. The tissue repair of claim 4, wherein said sleeve fits within the sleeve with a ratchet connection.

6. The tissue repair of claim 1, wherein

said at least one loop is molded to said first attachment point.

7. The method of claim 2, wherein said at least one

loop comprises a first loop and a second loop, and

said first loop is attached to said second attachment point, and

said second loop is attached to said third attachment point.

8. The tissue repair of claim 7, further comprising

a fourth attachment point secured in bone,

a third and fourth loop attached to an extending from said fourth attachment point,

a fifth attachment point secured in bone,

said third loop attached to said second attachment point, and

said fourth loop attached to said fifth attachment point.

9. A method of repairing tissue comprising

securing a first attachment in bone, said first attachment point having at least one loop,

forming a second attachment point in bone, and

attaching said at least one loop to said second attachment point.

10. The method of claim 9 further comprising

forming a third attachment point in bone, and attaching said at least one loop to said third attachment point.

11. The method of claim 10, wherein said at least one

loop comprises a first loop and a second loop and

said first loop is attached to said second attachment point, and

said second loop is attached to said third attachment point.

12. The method of claim 10, further comprising

securing a fourth attachment point in bone, said fourth attachment point having a third and fourth loop,

forming a fifth attachment point,

securing said third loop to said second attachment point, and

securing said fourth loop to said fifth attachment point.

13. A tissue repair comprising

a first attachment point secured in bone,

a suture loop attached to and extending from said first attachment point,

a second attachment point in the bone spaced from said first attachment point,

said suture loop passing through tissue and secured to said second attachment point.

14. The tissue repair of claim 13, wherein said second attachment point is a sleeve and plug, said plug capturing the suture loop and retained in said sleeve.

15. The tissue repair of claim 14, wherein said plug is retained in said sleeve by a ratchet connection.
