Knotless suture anchors
A readily implantable knotless suture anchor that de-couples the angle of insertion of the anchor from the tissue passage step and other steps of conventional procedures. An anchor provides an internal locking mechanism configured such that: suture knots do not have to be tied; suture and tissue tension can be easily adjusted intraoperatively; and suture passage and tensioning can be done at a variety of positions and angles. A method includes: passing a first suture through a patient's tissue and then through a loop of a shuttle suture; pulling the open end of the shuttle suture until the first suture passes through an internal suture locking mechanism; applying tension in the first suture until adequate tension is achieved with respect to the tissue; automatically engaging an internal locking member; and securing the first suture against further relative movement with respect to the anchor.

Individually lockable cinch loop micro suture anchor array for high density anatomical attachment of soft tissue to bone
A system of toggle type suture anchors is disclosed. The plurality of suture anchors is connected in series by a plurality of independently cinchable working suture loops with one working suture loop connecting each pair of anchors in series to form a chain. Each of the suture anchors as connected by working suture loops allows tensioning of the working suture between itself and the prior anchor implanted in the serial string. Further, each anchor includes a loop type locking mechanism to lock the cinchable working suture loop subsequent to tensioning so that the loop remains fixed in size during cyclic loading during joint use. This creates an independently tensioned suture stitch between each implanted suture anchor and the just previously implanted anchor. In total the system as implanted creates a high density, continuous array of anchor-to-anchor stitches for robust securement of soft tissue to bone.
