Abstract

A suture lock to be used with a suture thread. The suture lock comprises at least one passageway for receiving a suture thread, with the passageway having at least a portion of its length having a longitudinal side opening arranged to slidably receive the suture. The passageway is tapered inwardly and including an interior surface having inwardly converging teeth. The invention may also comprise a suture lock having an adjustable channel located within the suture lock. The channel may be adjusted between an open and a closed position, thereby allowing the suture to be secured. Translation of the suture itself may be utilized to adjust the positioning of the channel. The suture lock may contain a releasable device to retain the channel in multiple positions between the closed and open position.

Claims

1. A suture lock comprising:

a unitary body having a top side, a bottom side and a height extending therebetween, wherein said top side has a flat portion;

a substantially flat rear face extending between said top side and said bottom side;

an elongated opening formed in said body, said opening extending through said height of said body, said elongated opening having an open end and a terminal end; and

a plurality of teeth situated at least partially within said opening, each tooth having a longitudinal edge disposed within said elongated opening that is at least substantially linear along a portion thereof,

wherein said substantially linear portions of said longitudinal edges of all of said plurality of teeth are disposed at an oblique angle relative to said top side flat portion and said rear face, and wherein at least one of said plurality of teeth is located closer to said terminal end than said open end.

2. The suture lock according to claim 1 having a through bore located in said body independent from said opening, said bore intersecting said elongated opening.

3. The suture lock according to claim 2, said bore being oriented substantially perpendicular to said plurality of converging teeth.

4. A suture lock according to claim 2, further comprising a suture thread secured within said through bore.

5. The suture lock according to claim 1, said open end of said elongated opening being larger than said terminal end.

6. The suture lock according to claim 5, said terminal end being smaller than a suture thread.

7. The suture lock according to claim 6, said terminal end being V-shaped.

8. The suture lock according to claim 1, said teeth being tapered downwardly from said top side of said body toward said bottom side of said body.

9. The suture lock according to claim 1, said elongated opening having a length from said open end to the terminal end, and wherein said elongated opening is curved along at least a portion of said length.

10. The suture lock according to claim 1, the suture lock being comprised of a material that naturally dissolves within a human body.

11. The suture lock according to claim 1, said plurality of converging teeth being angled such that a substantially greater tension is required to slide a suture thread across said teeth in a first direction as opposed to a second direction.

12. The suture lock according to claim 1, wherein a suture thread may be unobstructedly placed within said opening.

13. The suture lock according to claim 1, said bottom side of said suture lock being configured to bridge an interface of sutured tissue substantially parallel to said interface.

14. The suture lock according to claim 1, the bottom side being substantially planar.

15. The suture lock according to claim 1, at least two of said teeth located closer to said terminal end of said opening than said open end.

16. The suture lock according to claim 15, all of said teeth located closer to said terminal end of said opening than said open end.

17. The suture lock according to claim 1, wherein said substantially linear portions of said longitudinal edges of said at least two teeth are coplanar.

18. The suture lock according to claim 1, wherein said edges of said at least two teeth intersect to form at least a portion of said terminal end.

19. The suture lock according to claim 1, wherein said longitudinal edges of at least two of said plurality of teeth converge towards each other.

20. The suture lock according to claim 1, wherein said substantially linear portions of said longitudinal edges of said at least two teeth are coplanar.

21. A device comprising:

a suture lock comprising a unitary body having

a substantially planar bottom side,

a top side having a first substantially planar portion that is substantially parallel to said bottom side and a second substantially planar portion extending at an obtuse angle from said first substantially planar portion,

a substantially planar rear face extending substantially orthogonally from said first substantially planar portion to said bottom side,

a substantially planar front face extending from said second substantially planar portion to said bottom side, intersecting said bottom side at an obtuse angle, and

a height extending between said top side and said bottom side;

an elongated channel having opposed sides, said elongated channel extending through said height of said body and having an open end formed in said rear face and a terminal end, said channel extending through said first substantially planar portion and said bottom side at said terminal end; and

a plurality of teeth situated at least partially within said opening, each tooth being disposed on one of said opposed sides, each tooth having a longitudinal edge disposed within said elongated channel, said longitudinal edge being at least substantially linear along a portion thereof,

a through bore formed through said front face into said elongated opening, said through bore being formed along a longitudinal axis in linear fluid communication with said open end of said elongated opening,

wherein said longitudinal edges of at least two of said teeth converge and wherein at least one of said teeth is located closer to said terminal end of said opening than said open end; and

a suture thread having a first thread portion extending through said through bore and a second thread portion disposed adjacent to said terminal end.

22. The device according to claim 21, wherein said suture thread is secured to said suture lock within said through bore.

23. The device according to claim 22, wherein said suture thread is adhered to said suture lock.
