Abstract

A suture anchoring and tensioning device is made from a resilient strip of polymeric or superelastic material adapted to be coiled into a tight spiral configuration that restricts movement of a suture entwined therein as the device coils about itself.

Claims

1. A suture anchoring device for use with a suture in a surgical procedure, comprising a resilient member having a coiled configuration, said resilient member being biased towards said coiled configuration from an uncoiled configuration, and said resilient member including holding means for holding a suture such that it becomes entwined within said resilient member as said resilient member moves from its said uncoiled configuration to its said coiled configuration.

2. A suture anchoring device in accordance with claim 1, wherein said resilient member is made from a polymeric plastic material having a memory shape.

3. A suture anchoring device in accordance with claim 1, wherein said resilient member is made from a superelastic material having a memory shape.

4. A suture anchoring device in accordance with claim 3, wherein said resilient member is made from a nickle-titanium alloy having a memory shape.

5. A suture anchoring device in accordance with claim 1, wherein said resilient member forms a tight spiral when said resilient member is in its said coiled configuration.

6. A suture anchoring device in accordance with claim 5, wherein said resilient member is a rectangularly-shaped thin planar strip when in its said uncoiled configuration.

7. A suture anchoring device in accordance with claim 6, wherein said planar strip includes a distal end, a proximal end, a pair of opposed planar surfaces, a pair of opposed end edges and a pair of opposed side edges.

8. A suture anchoring device in accordance with claim 7, wherein said distal end of said planar strip becomes an interior end of said spiral and said proximate end of said planar strip becomes an exterior end of said spiral, when said resilient member is in its said coiled configuration.

9. A suture anchoring device in accordance with claim 8, wherein one of said planar surfaces forms a spiralling outer wall and the other of said planar surfaces forms a spiralling inner wall, when said resilient member moves from its said uncoiled configuration to its said coiled configuration.

10. A suture anchoring device in accordance with claim 9, wherein a suture extending along said one planar surface is spiralled between said outer and inner walls, when said resilient member moves from its said uncoiled configuration to its said coiled configuration.

11. A suture anchoring device in accordance with claim 10, wherein said holding means prevents a spiralled suture from unspiralling, when said resilient member is in its said coiled configuration.

12. A suture anchoring device in accordance with claim 7, wherein said holding means includes a pair of openings, one of said openings being positioned proximate to one of said end edges of said planar strip, and the other of said openings being positioned proximate to the other of said end edges of said planar strip, each of said openings extending through said planar strip and being sized and shaped to receive a portion of a suture therein.

13. A suture anchoring device in accordance with claim 12, wherein each of said openings has a generally circular shape.

14. A suture anchoring device in accordance with claim 12, wherein said holding means further includes another opening extending through said planar strip and being positioned between said one opening and said other opening.

15. A suture anchoring device in accordance with claim 14, wherein each of said openings is generally U-shaped to thereby form a tab which is sized and shaped to hold a small portion of a suture passing thereunder.

16. A suture anchoring device in accordance with claim 7, wherein said holding means includes a pair of slots, one of said slots being formed in one of said side edges, and being positioned proximate to said distal end of said planar strip, and the other of said slots being formed in the other of said side edges and being positioned proximate to said proximal end of said planar strip, each of said slots being sized and shaped to receive a portion of a suture therein.

17. A suture anchoring device in accordance with claim 16, wherein each of said slots has a generally rectangular shape.

18. A suture anchoring device in accordance with claim 7, wherein said holding means includes a pair of slots, one of said slots being formed in one of said side edges and being positioned proximate to said distal end of said planar strip, and the other of said slots being formed in said side edge and being positioned proximate to said proximal end of said planar strip, each of said slots being sized and shaped to receive a portion of a suture therein.

19. A suture anchoring device in accordance with claim 18, wherein each of said slots has a generally rectangular shape.

20. A suture anchoring device in accordance with claim 7, wherein said holding means includes a pair of slots, one of said slots being formed in one of said end edges of said planar strip, and the other of said slots being formed in the other of said end edges of said planar strip, each of said slots being sized and shaped to receive a portion of a suture therein.

21. A suture anchoring device in accordance with claim 20, wherein each of said slots is generally L-shaped.

22. A suture anchoring device in accordance with claim 7, wherein said holding means includes a groove formed in said outer wall centrally positioned along and extending from one of said end edges of said planar strip to the other of said end edges of said planar strip, said groove being sized and shaped to receive a portion of a suture therein.

23. A suture anchoring device in accordance with claim 5, wherein said resilient member tensions an entwined suture when said resilient member is in it said coiled configuration.

24. A suture anchoring device in accordance with claim 1, wherein said holding means holds a pair of sutures.
