Methods and devices to treat diseased or injured musculoskeletal tissue
First Claim
1. A method of knotless suturing comprising:
- providing a delivery instrument carrying a first anchor and a second anchor, wherein a continuous length of suture is coupled directly with the first anchor and directly with the second anchor;
advancing the delivery instrument to a treatment region comprising treatment tissue;
placing the first anchor into a first region of the tissue;
coupling the suture to a portion of the treatment tissue;
attaching the second anchor to the first anchor;
tensioning the suture; and
securing the suture without knotting the suture by moving the suture through a cinching mechanism in the first or the second anchor, wherein the cinching mechanism is adapted to allow the suture to move through the cinching mechanism in a first direction while movement of the suture through the cinching mechanism in a second direction opposite the first direction is constrained independently of the position of the second anchor relative to the first anchor.

Abstract
A knotless suture anchoring system includes an outer anchor having a central channel and a distal tip adapted to penetrate tissue. An inner anchor is positionable in the central channel of the outer anchor and a locking feature on one or both of the inner and outer anchors retains the inner anchor within the central channel. A continuous length of suture is coupled with the inner and outer suture anchors and has a free end. At least one of the inner and the outer anchors also has a cinching mechanism that allows the suture to be tensioned by passage of the suture through the cinching mechanism in a first direction while movement of the suture through the cinching mechanism in a second direction opposite the first direction is constrained.
