  • Patent number: 8653319
    Abstract: A hydratable gel-forming polymer may be sterilized by chilling the polymer below ambient temperature and sterilizing the chilled polymer using ionizing radiation (e.g., E-Beam radiation). Doing so may reduce the degradation in physical properties caused by ionizing radiation sterilization of the polymer while at ambient temperature, and may preserve or retain desired hydration or gel-forming characteristics.

  • Patent number: 7678138
    Abstract: In one aspect of the invention, a cross-pin includes a distal portion having an axis, a distal end, and a proximal end. A proximal cylindrical portion includes a threaded exterior surface. A junction may be interposed between the distal and proximal portions to enable the proximal portion to rotate relative to the distal portion. In another aspect of the invention, a graft retaining system for retaining a graft in a bone tunnel includes a graft block having a proximal end and a distal end, and sized to fit within the bone tunnel. A cross pin transverse to the bone tunnel attaches the graft block adjacent the tunnel. An intermediate connector is attached to the graft block at a point distal to the cross pin and connects the graft to the graft block so as to apply compressive forces to the graft block.

  • Patent number: 7270666
    Abstract: A two piece graft fixation arrangement includes a graft block engageable with a graft and a transverse member engageable with the graft block to fix the graft block in a bone tunnel. Instruments and methods are presented for installing a graft in a bone tunnel and anchoring the graft with a transverse member placed through a transverse bore intersecting the bone tunnel.

  • Publication number: 20020188301
    Abstract: A system for inserting a tissue anchor during endoscopic or other surgical procedures. The system incorporates an insertion instrument for inserting into a surgical site of implantation an elongated, tissue anchor having, for example, a plurality of barbs outwardly extending from its body and a transverse head situated at its proximal end. The instrument is provided with an elongated needle received in the cannulation of the anchor, and an elongated pusher for pushing the anchor into tissue. The needle and pusher are fixedly attached to a handle and are situated in the lumen of a slidable, distally biased sheath or cannula for maintaining the tissue anchor, needle and pusher in alignment while the handle is pushed. The anchor may be inserted by a single-handed operation of the instrument through a simple pushing motion which causes the sheath to retract simultaneously with advancement of the handle to allow the anchor to be pushed into tissue.
