Surgical filament snare assemblies
A surgical filament snare assembly including an anchor capable of being fixated in bone and having a filament engagement feature. A first filament has a noose on a first portion of at least a first limb and has a second portion connected to the filament engagement feature of the anchor. Preferably, at least one free filament limb, which in some embodiments is a length of the first filament and in other embodiments is a second filament, is capable of being passed through tissue to be repaired and has at least one end passable through the noose to enable incremental tensioning of the tissue after the anchor is fixated in bone. The noose strangulates the free filament limb when tension is applied to at least one of the free filament limb and the noose.
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 suture engagement feature is positioned on a distal-most, terminal end of the anchor; and
wherein a knot of the first suture engages the suture engagement feature at the distal-most end of the anchor.
2. 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.
3. The surgical suture snare assembly of claim 1 , wherein the noose of the first suture is disposed within the passage of the anchor.
4. 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.
5. The surgical suture snare assembly of claim 1 , wherein the first suture does not contact a bone engaging surface of the anchor.
6. 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.
7. The surgical suture snare assembly of claim 6 , 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.
8. 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 suture engagement feature is positioned on a distal-most, terminal end of the anchor; and
wherein a knot of the first suture engages the suture engagement feature at the distal-most end of the anchor.
9. The surgical suture snare assembly of claim 8 , wherein the noose of the first suture is disposed within the passage of the anchor.
10. The surgical suture snare assembly of claim 8 , wherein the noose of the first suture is disposed beneath a skin surface when the second suture is passed therethrough.
11. The surgical suture snare assembly of claim 8 , wherein the first suture does not contact a bone engaging surface of the anchor.
12. 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 suture engagement feature is positioned on a distal-most, terminal end of the anchor; and
wherein a knot of the first suture engages the suture engagement feature at the distal-most end of the anchor.
13. The surgical suture snare assembly of claim 12 , 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.
14. The surgical suture snare assembly of claim 12 , wherein the noose of the first suture is disposed within the passage of the anchor.
15. The surgical suture snare assembly of claim 12 , wherein the noose of the first suture is disposed beneath a skin surface when the second suture is passed therethrough.
16. The surgical suture snare assembly of claim 12 , wherein the first suture does not contact a bone engaging surface of the anchor.
