Abstract

Claims (34)

1. A surgical suture snare assembly, comprising:

an anchor capable of being fixated in bone and having at least one passage and a suture engagement feature;

a first suture having a noose on a first portion of at least a first limb and having a second portion passing through the passage and connected to the suture engagement feature of the anchor; and

a second suture having at least a first free suture limb which is capable of being passed through tissue to be repaired and having at least one end passable through the noose to enable incremental tensioning of the tissue after the anchor is fixated in bone, the noose strangulating the first free suture limb when tension is applied to at least one of the first free suture limb and the noose,

wherein the first free suture limb forms a knot with another limb of the second suture, the knot being configured to be advanced distally to strangulate the first free suture limb within the noose, and

wherein the second portion is disposed distal to the suture engagement feature when the second portion is connected to the suture engagement feature of the anchor.

2. The surgical suture snare assembly of claim 1 , wherein the suture engagement feature is positioned on a distal-most, terminal end of the anchor.

3. The surgical suture snare assembly of claim 2 , wherein a knot of the first suture engages the suture engagement feature at the distal-most end of the anchor.

4. The surgical suture snare assembly of claim 1 , wherein the first suture comprises a knot configured to interact with the suture engagement feature to retain the first suture in a substantially fixed position relative to the anchor.

5. The surgical suture snare assembly of claim 1 , wherein the noose of the first suture is disposed within the passage of the anchor.

6. The surgical suture snare assembly of claim 1 , wherein the noose of the first suture is disposed beneath a skin surface when the second suture is passed therethrough.

7. The surgical suture snare assembly of claim 1 , wherein the first suture does not contact a bone engaging surface of the anchor.

8. The surgical suture snare assembly of claim 1 , further comprising a threader filament that extends through the noose of the first suture, the threader filament having a threader loop on a first end thereof and a free limb on a second end thereof, the threader filament being movably disposed relative to the noose of the first suture.

9. The surgical suture snare assembly of claim 8 , wherein at least one of the threader loop and the free limb extend proximal to the passage of the anchor, with at least one of the threader loop and the free limb extending proximal to a skin surface when the anchor is fixated in bone.

10. A surgical suture snare assembly, comprising:

an anchor capable of being fixated in bone and having at least one passage that extends along a central longitudinal axis of the anchor, and a suture engagement feature;

a first suture having a noose on a first portion of at least a first limb and having a second portion passing through the passage and connected to the suture engagement feature of the anchor; and

a second suture having at least a first free suture limb which is capable of being passed through tissue to be repaired and having at least one end passable through the noose to enable incremental tensioning of the tissue after the anchor is fixated in bone, the noose strangulating the first free suture limb when tension is applied to at least one of the first free suture limb and the noose,

wherein the suture engagement feature is positioned on a distal-most, terminal end of the anchor.

11. The surgical suture snare assembly of claim 10 , wherein a knot of the first suture engages the suture engagement feature at the distal-most end of the anchor.

12. The surgical suture snare assembly of claim 10 , wherein the noose of the first suture is disposed within the passage of the anchor.

13. The surgical suture snare assembly of claim 10 , wherein the noose of the first suture is disposed beneath a skin surface when the second suture is passed therethrough.

14. The surgical suture snare assembly of claim 10 , wherein the first suture does not contact a bone engaging surface of the anchor.

15. The surgical suture snare assembly of claim 10 , wherein the noose is defined by a knot that is formed in the first suture.

16. A surgical suture snare assembly, comprising:

an anchor capable of being fixated in bone and having at least one passage and a suture engagement feature;

a first suture having a noose on a first portion of at least a first limb and having a second portion passing through the passage and connected to the suture engagement feature of the anchor; and

a second suture having at least a first free suture limb which is capable of being passed through tissue to be repaired and having at least one end passable through the noose to enable incremental tensioning of the tissue after the anchor is fixated in bone, the noose strangulating the first free suture limb when tension is applied to at least one of the first free suture limb and the noose,

wherein the noose of the first suture is disposed within the passage of the anchor, and

wherein the second portion is disposed distal to the suture engagement feature when the second portion is connected to the suture engagement feature of the anchor.

17. The surgical suture snare assembly of claim 16 , wherein the suture engagement feature is positioned on a distal-most, terminal end of the anchor.

18. The surgical suture snare assembly of claim 17 , wherein a knot of the first suture engages the suture engagement feature at the distal-most end of the anchor.

19. The surgical suture snare assembly of claim 16 , wherein the first suture comprises a knot configured to interact with the suture engagement feature to retain the first suture in a substantially fixed position relative to the anchor.

20. The surgical suture snare assembly of claim 16 , wherein the first suture does not contact a bone engaging surface of the anchor.
