A surgical system includes an anchor and an introducer provided to deliver the anchor into tissue. The anchor includes a body having a pointed leading end that is configured to pierce the tissue, a spine projecting radially away from the body and having a width and a height configured to allow the spine to engage with the tissue, an eyelet attached to a trailing end of the body, and a length of suture attached to the eyelet. The introducer includes a cannula with a pointed distal end, an opening formed in the cannula that is sized to receive the body of the anchor, and a slot formed in a wall of the cannula at a distal end portion of the cannula and sized to receive the width of the spine.
