A surgical system (20) includes an anchor (22) and an introducer (24) provided to deliver the anchor into tissue. The anchor includes a body (30) having a pointed leading end (32) that is configured to pierce the tissue, a spine (34) 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 (36) attached to a trailing end of the body, and a length of suture (23) attached to the eyelet. The introducer includes a cannula (40) with a pointed distal end (44), an opening (46) formed in the cannula that is sized to receive the body of the anchor, and a slot (92) formed in a wall of the cannula at a distal end portion of the cannula and sized to receive the width of the spine.
