Soft anchors with soft eyelets
Soft anchor constructs and methods for soft tissue to bone repairs. The soft anchors may be knotted or knotless constructs. The soft anchors include a body formed of various soft materials (including, but not limited to, suture) and provided in various shapes and configurations that confer the anchors the ability to be easily inserted within bone tunnels or sockets and be bunched up within the bone tunnels or sockets. At least one closed loop or soft eyelet is attached to the soft anchor to allow additional sliding strands and/or shuttle/pull devices (suture passing devices) to pass through the eyelet and aid in the knotted or knotless fixation of tissue to bone.
1. A soft anchor for surgical repairs comprising:
an anchor body formed of a flexible material designed to be compressed from a first, non-compressed position to a second, compressed position, the anchor body including first and second openings; and
at least one flexible strand attached to the anchor body, the flexible strand extending through the anchor body such that a first end of the flexible strand extends through the first opening and a second end of the flexible strand extends through the second opening, the first end of the flexible strand terminating in an eyelet, and the second end extending through the eyelet and extending through a splice in the second end of the flexible strand to form a closed loop.
2. The soft anchor of claim 1 , wherein the closed loop forms a self-cinching flexible closed loop with an adjustable perimeter.
3. The soft anchor of claim 1 , wherein the at least one flexible strand, when pulled, is designed to compress the flexible material from the first, non-compressed position to the second, compressed position.
4. The soft anchor of claim 1 , wherein the anchor body is in the form of a sleeve, a sheath, a tube or a hollow construct.
5. The soft anchor of claim 1 , wherein the anchor body is a braided sheath formed of polyester.
6. The soft anchor of claim 1 , wherein the at least one flexible strand is a suture strand or a suture tape.
7. The soft anchor of claim 1 , wherein the anchor is knotted or knotless.
8. A soft anchor for fixation of soft tissue to bone, comprising:
a tubular sleeve formed of a flexible material, a cannulation and two ends;
a flexible strand with a first end and a second end, the flexible strand extending through at least a portion of the cannulation of the tubular sleeve and with the first end exiting a first opening of the tubular sleeve and with the second end exiting a second opening of the tubular sleeve, the first end terminating in an eyelet; and
a shuttling device having one portion coupled to the second end of the flexible strand and another portion extending through the eyelet of the first end of the flexible strand,
wherein the second end of the flexible strand passes through the eyelet at the first end and passes through a splice in the second end of the flexible strand, to form a closed loop having an adjustable perimeter.
9. The soft anchor of claim 8 , wherein the tubular sleeve is formed of a coreless braid of polyester or polyethylene.
10. The soft anchor of claim 8 , wherein the flexible strand is a coreless suture.
11. The soft anchor of claim 8 , wherein the anchor is a suture-based anchor.
12. The soft anchor of claim 8 , wherein the shuttling device is a nitinol suture passer.
13. A method of knotless fixation of soft tissue to bone, comprising the steps of:
providing a soft anchor comprising a tubular sleeve or sheath formed of a flexible material and having a first length, a cannulation and two ends; and a flexible strand attached to the tubular sleeve, the flexible strand forming an eyelet at a first end and having a shuttling device attached to a portion of a second end of the flexible strand;
inserting the soft anchor into a socket or tunnel formed into bone so that the soft anchor bunches up within the socket or tunnel;
passing the second end of the flexible strand around tissue to be fixated and then through an eyelet of the shuttling device;
pulling the shuttling device so that the second end of the flexible strand passes through the eyelet of the first end of the flexible strand and then passes through the second end of the flexible strand to form a splice through itself and a self-cinching closed loop with an adjustable perimeter;
removing the shuttling device; and
pulling on the second end to provide tensioning of soft tissue relative to the bone.
14. The method of claim 13 , wherein the shuttling device is a suture passer.
15. The method of claim 13 , further comprising the step of securing the soft anchor to an inserter or driver.
16. The method of claim 13 , further comprising the step of providing an attachment suture pre-assembled with the anchor to hold the anchor onto an inserter.
