Abstract: An apparatus and method for delivering or installing a surgical suture or suture-like implant into soft tissue, such as the meniscus of the knee, for example, for reattachment or repair of that tissue. The apparatus and method facilitate ease of placement of the suture or implant by the surgeon, protect surrounding tissue and nerves from damage during use, and permit suturing to occur through a single body portal. An injury to soft tissue, such as a tear in the meniscus of the knee joint or detachment of soft tissue from bone, is repaired through a single body portal by installing a surgical suture across the injury, tear, or detachment and passing that suture back through the body portal so that the suture can be joined and the injury, tear, or detachment can be reapproximated by the surgeon while working through the single body portal.

Abstract: A medullary suture anchor including an elongated body having flat, angled end portions. A central bore extends through the body transverse to and centered on the longitudinal axis of the anchor. The anchor further includes channels extending along the sides of the body, such that a suture journaled through the central bore may be received within the longitudinal grooves during insertion of the anchor into a medullary canal.
Abstract: A surgical bone screw having a head which has asymmetrical radii relative to the central axis of the screw. The cross-section of the head is configured as a lobular shape having a constant radii along one hemisphere of the head, and smaller radii along the opposing hemisphere of the head, with the smallest radius existing approximately perpendicular to the midline of the head member. The asymmetry of the head minimizes surface area of the screw protruding above the bone surface.
