Soft suture-based anchors
Suture constructs and methods for soft tissue to bone repairs. The suture construct is a soft, suture-based anchor which is self-cinching and has a specific, accordion-type configuration (i.e., with the ability to fold from a first, extended position to a second, folded or compressed position). The suture-based anchor may be formed essentially of a flexible material such as a high strength surgical suture, suture chain, or suture.
1. A knotless folding anchor for surgical repairs comprising:
a folding tube of suture tape; and
a length of suture,
wherein the folding tube of suture tape is designed to be compressed from an extended, non-folded position to a compressed, folded position, the folding tube of suture tape being provided with apertures to allow the length of suture to pass therethrough so that, when the length of suture is pulled, the folding tube of suture tape compresses from the extended, non-folded position to the compressed, folded position, the folding tube of suture tape being configured to lodge into a bone tunnel or socket in the compressed, folded position.
2. The anchor of claim 1 , wherein the anchor consists essentially of suture.
3. The anchor of claim 1 , wherein the length of suture attaches to the folding tube of suture tape by being passed through a length of the suture tape at different points throughout the length of the suture tape.
4. The anchor of claim 1 , wherein the length of suture is attached to the suture tape by passing one end of the length of suture through different points spaced apart along a length of the suture tape, beginning with a first point, and then passing the other end of the length of suture at a position adjacent the first point to form a loop.
5. The anchor of claim 4 , wherein, when the two ends of the length of suture are pulled, the loop collapses and compresses the length of suture tape forming the folding tube from the extended, non-folded position to the compressed, folded position.
6. The anchor of claim 5 , wherein in the compressed, folded position, the length of suture tape forms a plurality of folds in the shape of an accordion.
