Abstract

A suture system including a suture construct having a first reduction construct configured to be selectively arranged in an expanded state and a reduced state. The first reduction construct includes a first locking limb, a first contractible loop, and a first opposed loop disposed generally opposite to the first contractible loop, wherein reduction of the first opposed loop contracts the first contractible loop from the expanded state into the reduced state and secures the suture construct in the reduced state. The suture construct may also include a second reduction construct. Optionally, the suture system includes a first and a second pusher tube defining a first and a second lumen, respectively, wherein each pusher tubes are advanced over portions of opposed loops, respectively, and wherein distal portions of opposed loops extend beyond the pusher tubes, respectively.

Claims

1. A suture system comprising:

a suture construct including a first reduction construct configured to be selectively arranged in an expanded state and a reduced state, said first reduction construct comprising;

a first locking limb;

a first contractible loop; and

a first opposed loop disposed generally opposite to said first contractible loop, wherein reduction of said first opposed loop contracts said first contractible loop from said expanded state into said reduced state and secures said suture construct in said reduced state;

a suture pin configured to be disposed through said first contractible loop, wherein said suture pin includes an elongated main body having a generally circular cross-section extending between a first and a second enlarged portion, said first and said second enlarge portions extending outwardly from said elongated main body; and

a first pusher tube defining a first lumen, wherein the first pusher tube is advanced over portions of said first opposed loop, and wherein a distal portion of the first opposed loop extend beyond the first pusher tube.

2. The suture system of claim 1, wherein said first and said second enlarged portions include a generally concaved bone facing surface.

3. The suture system of claim 1, wherein said first contractible loop and said first opposed loop are separated by a first loop defined by a first knot.

4. The suture system of claim 3, wherein a first portion of said first opposed loop extends through said first loop from said first contractible loop, and wherein a second portion of said first opposed loop extends through said first loop and terminates at said first locking limb.

5. The suture system of claim 4, wherein a first portion of said first contractible loop extends through said first loop from said first opposed loop, and wherein a second portion of said first contractible loop extends from and terminates at said first knot.

6. The suture system of claim 3, wherein a length of said first contractible loop is reduced by pulling said locking limb, causing a portion of said suture to pass from said first contractible loop and through said first knot, and through said first opposed loop.

7. The suture system of claim 3, wherein said first locking limb is configured to be disposed through said first opposed loop to lock said suture construct.

8. The suture system of claim 1, further comprising a second reduction construct separated from said first reduction construct by a bridge, said second reduction construct comprising:

a second locking limb;

a second contractible loop; and

a second opposed loop disposed generally opposite to said second contractible loop, wherein reduction of said second opposed loop contracts said second contractible loop.

9. The suture system of claim 8, wherein said first and said second contractible loops and said first and said second opposed loops are separated by a first and a second loop defined by first and second knots, respectively.

10. The suture system of claim 9, wherein first portions of said first and said second opposed loops extend through said first and said second loops from said first and said second contractible loops, respectively, and wherein second portions of said first and said second opposed loops extend through said first and said second loops and terminate at said first and said second locking limbs, respectively.

11. The suture system of claim 10, wherein first portions of said first and said second contractible loops extend through said first and said second loops from said first and said second opposed loops, respectively, and wherein second portions of said first and said second contractible loops extend from and terminate at said first and said second knots, respectively.

12. The suture system of claim 9, wherein said first and said second locking limbs are passed through said first and said second opposed loops, respectively.

13. The suture system of claim 12, further comprising a second pusher tube defining a second lumen, wherein said second pusher tube is advanced over portions of said second opposed loops, and wherein distal portions of said second opposed loop extend beyond said second pusher tubes.

14. The suture system of claim 8, further comprising a suture pin configured to be disposed through said first and said second contractible loops.

15. The suture system of claim 8, further comprising a suture plate configured to be proximate to said bridge, said suture plate including two apertures spaced apart from each other a distance substantially equal to a length of said bridge.
