  • Patent number: 7967843
    Abstract: An apparatus and method for fixing a selected graft relative to a selected anatomical portion. An anchor may be provided that may be interconnected with a selected graft portion that is operable to pass through a selected bore and then moved into an operable position to engage a selected portion of the bore to substantially eliminate the possibility of the graft moving in an unselected direction through the bore. In addition, a spacer member may be used to expand a selected portion of the graft to reduce localized stress and may increase ingrowth into a selected bony portion.

    Abstract: Methods of attaching a soft tissue to an adjacent bone at a defect site are provided. At least one adjustable loop of a flexible construct is passed through the soft tissue. The at least one adjustable loop is passed through a passage construct. A locking member is passed through the at least one adjustable loop and the adjustable loop is reduced about or within the locking member such that the at least one loop is frictionally retained in the passage construct and locked in place by the locking member to thereby secure the soft tissue.

  • Publication number: 20110098727
    Abstract: A method and apparatus for securing soft tissue to bone can include forming a bore in the bone and carrying a flexible suture anchor into the bore. The flexible anchor can include a passage and can be coupled to a suture construct. The suture construct can include at least one self-locking adjustable loop, and the flexible anchor can include a first profile while being carried into the bore. A shape of the flexible anchor can be changed from the first profile to a second profile forming an anchoring mass to retain the flexible anchor in the bore. Tension can be applied to a portion of the suture construct to reduce a size of the self-locking adjustable loop and secure the soft tissue relative to the flexible anchor and the bone.

  • Publication number: 20100222812
    Abstract: A suture anchor for anchoring a suture in the selected portion of an anatomical portion for fixing a suture thereto. The suture anchor including an anatomical engaging portion and a suture engaging portion wherein both the anatomical engaging portion and a suture engaging portion are adopted to be substantially disposed below an exterior of the anatomical portion after implantation. Suture eyelets are provided in the suture engaging section and a suture passage is formed to interconnect the eyelets to allow a suture to be easily threaded in the suture engaging section from the first eyelet to the second eyelet.
