Abstract

A device having one or more adjustable loops or coils associated with an implant body for use in soft tissue reconstructions is provided. One exemplary embodiment of a device includes a body and a suture filament, with the filament being used to form a self-locking sliding knot disposed on a top side of the body and a plurality of adjustable coils that are substantially disposed on the body's bottom side. Terminal ends of the filament located above the body's top side can be passed through an opening of a Lark's Head knot from opposite sides, thus forming a self-locking sliding knot, and then the terminal ends can be tensioned to adjust a circumference of the coils. Changing a coil's circumference changes a location of a ligament graft disposed on the coil. Other configurations of devices and systems, as well as methods for performing ACL repairs, are also provided.

First claim

What is claimed is:

1. A surgical implant, comprising:
a body having a plurality of thru-holes formed therein;
a first suture filament extending through the body and configured to form:
a self-locking knot, the self-locking knot defining a collapsible opening that is located on a top side of the body, and
one or more coils arranged such that each coil is formed as a result of the suture filament being disposed through at least two of the plurality of thru-holes of the body such that a portion of each coil is disposed on the top side of the body and a portion of each coil is disposed on a bottom side of the body, and
a second suture filament extending longitudinally through the body, wherein the self-locking knot has:
a first portion of the first suture filament that is intermediate a first terminal end thereof and the one or more coils, is disposed on the top side of the body and extending through the collapsible opening from a first side of the opening, and
a second portion of the first suture filament that is intermediate a second terminal end thereof and the one or more coils disposed on the top side of the body and passed through the collapsible opening from a second, opposite side of the opening, and

wherein the collapsible opening is configured to collapse and move toward the body when tension is applied to at least one of the first and second terminal ends.

2. The implant of claim 1 , wherein the one or more coils comprises a first coil and a second coil formed by a third portion of the suture filament extending between the self-locking knot and the first terminal end, and a third coil and a fourth coil formed by a fourth portion of the suture filament extending between the self-locking knot and the second terminal end.

3. The implant of claim 2 , wherein the plurality of thru-holes comprises two outer thru-holes and two inner thru-holes, each outer thru-hole being located adjacent to respective opposed terminal ends of the body and the inner thru-holes being disposed between the outer thru-holes, and wherein the first and third coils pass through each of the outer thru-holes and the second and fourth coils pass through each of the inner thru-holes.

4. The implant of claim 2 , wherein the plurality of thru-holes comprises two outer thru-holes and two inner thru-holes, each outer thru-hole being located adjacent to respective opposed terminal ends of the body and the inner thru-holes being disposed between the outer thru-holes, and wherein the first, second, third, and fourth coils each pass through each of the inner thru-holes.

5. The implant of claim 1 , wherein at least one coil of the one or more coils is configured such that a circumference thereof can be changed by applying tension to at least one of the first and second terminal ends.

6. The implant of claim 1 , wherein the one or more coils is configured such that a circumference of one coil of the one or more coils can be adjusted independent of adjusting a circumference of another coil of the one or more coils.

7. The implant of claim 1 , wherein the self-locking knot comprises a Lark's Head knot.

8. The implant of claim 1 , wherein the body includes a longitudinal bore through which the second suture filament extends, and wherein the second suture filament includes a protrusion positioned outside of the longitudinal bore that has a diameter larger than the longitudinal bore to prevent passage of the protrusion through the longitudinal bore.

9. The implant of claim 8 , wherein the protrusion is a knot.

10. The implant of claim 1 , further comprising;
a first sleeve disposed over a third portion of the suture filament that extends between the self-locking knot and the first terminal end, the first sleeve being located on the top side of the body; and
a second sleeve disposed over a fourth portion of the suture filament that extends between the self-locking knot and the second terminal end, the second sleeve being located on the top side of the body.

11. The implant of claim 10 , wherein the first sleeve disposed over the third portion of the suture filament and the second sleeve disposed over the fourth portion of the suture filament are a same sleeve, and a portion of the same sleeve is disposed around the bottom side of the body.

12. A surgical implant, comprising:
a body having a longitudinal axis, a longitudinal bore, and a plurality of thru-holes, the plurality of thru-holes extending in a direction transverse to the longitudinal axis of the body from a top side to a bottom side of the body;
a first suture filament having first and second terminal ends; and
a second suture filament extending through the longitudinal bore, the second suture filament including a protrusion positioned outside of the longitudinal bore that has a diameter larger than the longitudinal bore to prevent passage of the protrusion through the longitudinal bore,
the first suture filament being associated with the body to form:
a self-locking knot, the self-locking knot including a collapsible opening, located on the top side of the body, and
a plurality of coils formed as a result of the terminal ends of the first suture filament passing through a thru-hole from the top side of the body to the bottom side of the body and then passing through a different thru-hole of the body back to the top side of the body,

wherein the self-locking knot is formed with the first terminal end passing through the collapsible portion from a first side of the opening and the second terminal end passing through a second, opposite side of the opening, and
wherein the collapsible opening is configured to collapse and move toward the body when tension is applied to at least one of the first and second terminal ends.

13. The implant of claim 12 , wherein the plurality of coils comprises a first coil and a second coil formed by a first portion of the suture filament extending between the self-locking knot and the first terminal end, and a third coil and a fourth coil formed by a second portion of the suture filament extending between the self-locking knot and the second terminal end.

14. The implant of claim 13 , wherein the plurality of thru-holes comprises two outer thru-holes and two inner thru-holes, each outer thru-hole being located adjacent to respective opposed terminal ends of the body and the inner thru-holes being disposed between the outer thru-holes, and wherein the first and third coils pass through each of the outer thru-holes and the second and fourth coils pass through each of the inner thru-holes.

15. The implant of claim 13 , wherein the plurality of thru-holes comprises two outer thru-holes and two inner thru-holes, each outer thru-hole being located adjacent to respective opposed terminal ends of the body and the inner thru-holes being disposed between the outer thru-holes, and wherein the first, second, third, and fourth coils each pass through each of the inner thru-holes.

16. The implant of claim 12 , wherein at least one coil of the plurality of coils is configured such that a circumference thereof can be changed by applying tension to at least one of the first and second terminal ends.

17. The implant of claim 12 , wherein the plurality of coils is configured such that a circumference of one coil of the plurality of coils can be adjusted independent of adjusting a circumference of another coil of the plurality of coils.

18. The implant of claim 12 , wherein the self-locking knot comprises a Lark's Head knot.

19. The implant of claim 12 , wherein protrusion is a knot.
