Soft button assembly and procedure
A suture construct having a soft button, defining a multiplicity of first apertures and a set of second apertures. Also, a suture loop assembly has a suture defining a lumen and forming a double loop, formed by a double trap having a first end and a second end, formed in a trap region of the suture, and in which a first portion of the suture is threaded through the trap region lumen from the first end to the second end and the first portion extends out from the second end, and a second portion of the suture is threaded through the trap region lumen from the second end to the first end, and the second portion extends out from the first end. Finally, the double loop passes through the set of second apertures of the soft button.
1. A suture construct, comprising:
a) a soft button, comprising a sheet of flexible material defining a multiplicity of first apertures and a set of second apertures;
b) a suture loop assembly, having a suture defining a lumen and forming a double loop, formed by a double trap having a first end and a second end, formed in a double trap region of said suture, and in which a first portion of said suture is threaded through said double trap region of said lumen from said first end to said second end and said first portion extends out from said second end, and a second portion of said suture is threaded through said trap region lumen from said second end to said first end, and said second portion extends out from said first end and wherein said double loop passes through said set of second apertures of said soft button.
2. The suture construct of claim 1 , wherein said soft button is positioned on said double loop in a location opposed to said double trap.
3. The suture construct of claim 2 , further including an additional soft button, threaded onto said double trap.
4. The suture construct of claim 1 , wherein said first and second apertures are interstices of a weave of biocompatible fibers, comprising said sheet of flexible material.
5. The suture construct of claim 1 , wherein said first and second apertures are laser-drilled apertures in a sheet of flexible polymeric material, comprising said sheet of flexible material.
6. The suture construct of claim 1 , wherein said set of second apertures consists of six apertures, and wherein said soft button is formed into three folds by said double loop passing through said six apertures.
7. The suture construct of claim 1 , wherein said sheet of flexible material is formed of woven material.
8. The suture construct of claim 7 , wherein said woven material is made of poly ethylene fibers.
9. The suture construct of claim 1 , wherein said sheet of flexible material is formed of expanded Poly Tetrafluoroethylene (ePTFE).
10. The suture construct of claim 1 , wherein said sheet of flexible material is formed of a sheet of flexible polymeric material that has been laser drilled to create apertures.
11. The suture construct of claim 1 , further having two additional traps, defined by a suture portion entering, passing through and exiting a portion of the lumen of another suture portion, one of said two additional traps on either side of said double trap.
12. The suture construct of claim 1 , wherein said set of second apertures consists of at least six apertures, and wherein said soft button is formed into at least three folds by said double loop passing through said six apertures.
