Abstract

A suture tensioning and fixation device comprises a suture thread and a suture retaining element. The retaining element has a first suture thread engaging portion on the first end, a second suture thread engaging portion opposite the first suture thread engaging portion, and a third, substantially centrally located suture thread engaging portion. The retaining element is adapted such that segments of the suture thread can be interwoven between the suture thread engaging portions of the retaining element. The suture thread engaging portions of the retaining element are adapted to frictionally hold the interwoven segments of suture thread. Localized melting of the retaining element where it contacts the suture thread segments establishes a weld and bonds the suture thread to the retaining element in a knotless joint.

Claims

1. A suture tensioning and fixation kit, comprising:

a. a suture thread; and

b. a suture retaining element having a first suture thread engaging portion on one end of the retaining element, a second suture thread engaging portion opposite the first suture thread engaging portion, and a third, substantially centrally located, suture thread engaging portion;

said suture retaining element being a substantially planar sheet for frictionally engaging suture thread;

wherein segments of the suture thread can be interwoven between the suture thread engaging portions, wherein the retaining element is heat bondable to the suture thread.

2. The device according to claim 1, wherein the retaining element is a plastic material having a melting point lower than the melting point of the suture thread.

3. The device according to claim 1, wherein the centrally located suture engaging portion of the retaining element includes one or more channels for the suture thread.

4. The device according to claim 3, wherein the centrally located suture engaging portion of the channel includes one or more projecting tabs.

6. The device according to claim 1, wherein the retaining element has a figure eight shape.

7. The device according to claim 1, wherein the suture thread is a braided suture thread.

5. The device according to claim l, wherein the retaining element has a serpentine shape.

8. A suture tensioning and fixation kit, comprising:

a suture retaining element having a first suture thread engaging portion on one end of the retaining element, a second suture thread engaging portion opposite the first suture thread engaging portion, and a third, substantially centrally located, suture thread engaging portion;

said suture retaining element being a substantially planar sheet for frictionally engaging a suture thread;

wherein segments of the suture thread can be interwoven between the suture thread engaging portions, wherein the retaining element is heat bondable to the suture thread.

9. The device according to claim 8, wherein the retaining element is a plastic material having a melting point lower than the melting point of the suture thread.

10. The device according to claim 8, wherein the centrally located suture engaging portion of the retaining element includes one or more channels for the suture thread.

11. The device according to claim 10, wherein the centrally located suture engaging portion of the channel includes one or more projecting tabs.

12. The device according to claim 8, wherein the retaining element has a serpentine shape.

13. The device according to claim 8, wherein the retaining element has a figure eight shape.

14. The device according to claim 8, wherein the suture thread is a braided suture thread.
