Method and apparatus for soft tissue attachment
View Patent ↗An anchor assembly for retaining a graft in an anatomy. The anchor assembly includes an anchor body, a flexible connector, and a graft holding member. The anchor body includes a first connector bore defined by the anchor body. The flexible connector extends through the first connector bore. The graft holding member is attached to the flexible connector and is configured to hold the graft.
1. An anchor assembly configured for retaining a graft in an anatomy comprising:
an anchor body having a first connector bore defined by the anchor body;
a flexible connector extending through the first connector bore; and
a graft holding member configured to hold the graft, the graft holding member having an attachment member extending therefrom that is engaged with the flexible connector to link the anchor body to the graft holding member, and a surface configured to maintain separation of a first portion of the graft from a second portion of the graft, wherein the graft holding member is configured to he attached to the flexible connector via a third portion of the graft.
2. The anchor assembly of claim 1 , wherein the anchor body defines a second connector bore spaced apart from the first connector bore, the first connector bore extends substantially parallel to the second connector bore.
3. The anchor assembly of claim 2 , wherein the flexible connector extends through both the first connector bore and the second connector bore.
4. The anchor assembly of claim 1 , further comprising a flexible activation member connected to the anchor body.
5. The anchor assembly of claim 4 , wherein the flexible connector and the flexible activation member are each sutures.
6. The anchor assembly of claim 1 , further comprising:
an activation bore defined by the anchor body; and
a flexible activation member extending through the activation bore.
7. The anchor assembly of claim 1 , wherein the attachment member is flexible.
8. The anchor assembly of claim 1 , wherein the anchor body includes a button.
9. The anchor assembly of claim 1 , wherein the anchor body is rigid and monolithic.
10. The anchor assembly of claim 1 , wherein the anchor body is configured to fit within a bone tunnel.
11. The anchor assembly of claim 1 , wherein the graft holding member is configured to hold the graft with the graft positioned over the graft holding member.
12. An anchor assembly configured for retaining a graft in an anatomy comprising:
an anchor body including a first connector bore defined by the anchor body and a second connector bore defined by the anchor body, the first connector bore extends substantially parallel to the second connector bore;
a flexible connector extending through both the first connector bore and the second connector bore;
a graft support member configured to support the graft, wherein the graft support member includes an attachment member extending therefrom that is engaged with the flexible connector to link the anchor body to the graft support member, the graft support member including a plurality of ridges to maintain separation of a first portion of the graft from a second portion of the graft, wherein the graft support member is configured to be attached to the flexible connector via a third portion of the graft; and
a flexible activation member connected to the anchor body.
13. The anchor assembly of claim 12 , wherein the anchor body is rigid.
14. The anchor assembly of claim 12 , wherein the flexible connector and the flexible activation member are both sutures.
15. The anchor assembly of claim 12 , wherein the graft is configured to replace an anterior cruciate ligament.
16. The anchor assembly of claim 12 , wherein the graft support member is configured to fit within a bone tunnel to support the graft in the bone tunnel.
17. The anchor assembly of claim 12 , wherein the graft support member is configured to support the graft with the graft positioned over the graft support member.
