Multiple pass self-cinching suture construct
A multiple pass self-cinching suture construct includes a strand of suture material. A fixed loop is formed at one end, and an adjustable loop is formed at the opposite end. A self-cinching section is disposed between the fixed loop and the adjustable loop. The self-cinching section includes a first pass of a tag end axially through the interior of the self-cinching section to form the fixed loop. The opposite tag end passes axially through the interior of two co-axial suture segments inside the self-cinching section, forming an adjustable loop. As the adjustable loop tag end is pulled, tension is applied and the self-cinching section constricts to maintain tension. In some embodiments, the self-cinching section includes at least four segments of the strand of suture material co-axially aligned along the self-cinching section.
1. A suture construct apparatus, comprising:
a suture strand including an adjustable loop at a first end and a fixed loop at a second end;
a self-cinching section disposed on the suture strand between the adjustable loop and the fixed loop, the self-cinching section including first and second segments of the suture strand co-axially aligned;
a first tag end of the suture strand extending axially inside both the first and second segments of the suture strand in the self-cinching section; and
a second tag end of the suture strand housed axially inside a portion of the first tag end.
2. The apparatus of claim 1 , wherein the second tag end housed axially inside a portion of the first tag end extends into and through the self-cinching section with the first tag end.
3. The apparatus of claim 2 , wherein the first tag end exits a portion of the fixed loop between the second end and the self-cinching section.
4. The apparatus of claim 3 , wherein the second tag end housed axially inside a portion of the first tag end exits the portion of the fixed loop between the second end and the self-cinching section with the first tag end when the suture construct is tightened.
5. The apparatus of claim 2 , further comprising a shuttling suture disposed on the fixed loop.
6. The apparatus of claim 5 , wherein a distal end of the first tag end is removably housed inside a portion of the shuttling suture.
7. The apparatus of claim 6 , further comprising a continuous loop freely disposed on the adjustable loop.
8. The apparatus of claim 7 , wherein the first tag end includes a progressive narrowing taper toward the distal end of first tag end.
9. The apparatus of claim 8 , further comprising an anchor disposed on the fixed loop.
10. The apparatus of claim 9 , wherein the anchor comprises a soft anchor.
11. The apparatus of claim 10 , further comprising:
a shuttling suture loop disposed on an end of the shuttling suture, wherein the shuttling suture loop is disposed on the fixed loop.
12. The apparatus of claim 11 , wherein the shuttling suture loop extends around the anchor on the fixed loop.
13. A suture construct apparatus, comprising:
a suture strand including an adjustable loop at a first end and a fixed loop at a second end opposite the first end; and
a self-cinching section disposed on the suture strand between the fixed loop and the adjustable loop,
wherein the self-cinching section includes two or more co-axially aligned segments of the suture strand extending axially inside the self-cinching section.
14. The apparatus of claim 13 , further comprising a first tag end of the suture strand exiting the fixed loop between the second end and the self-cinching section.
15. The apparatus of claim 14 , further comprising a first shuttling suture disposed on the fixed loop.
16. The apparatus of claim 15 , further comprising a continuous loop freely disposed on the adjustable loop.
17. The apparatus of claim 16 , further comprising a second shuttling suture disposed on the continuous loop.
18. The apparatus of claim 17 , further comprising an anchor disposed on the fixed loop.
19. A suture construct apparatus, comprising:
a suture strand having a first tag end and a second tag end;
an adjustable loop formed by the first tag end;
a fixed loop formed by the second tag end; and
a self-cinching section on the suture strand between the fixed loop and the adjustable loop,
wherein a portion of the second tag end extends axially through the self-cinching section inside the suture strand toward the adjustable loop,
wherein the second tag end is housed in a portion of the first tag end passing through the self-cinching section toward the fixed loop, and
wherein at least two segments of the suture strand are co-axially aligned inside the self-cinching section of the suture strand.
20. The apparatus of claim 19 , wherein the first tag end and the second tag end housed in a portion of the first tag end both exit the suture strand at a location on the fixed loop.
