  • Patent number: 8486074
    Abstract: The invention is directed toward a surgical kit having component parts capable of use to prepare a cartilage implant plug from allograft condyle. The kit comprises a sizing gauge used to measure surface of the allograft condyle so that a cartilage implant plug can be removed that corresponds to the contours of the defect site excised on a patient. An adjustable guide member is mounted in a fixed orientation over the allograft condyle in which a cylindrical graft cutter for cutting a cylindrical allograft bone plug having a cartilage cap and a bone end portion. A chamfering tool is used for chamfering the bone end of the allograft bone plug.

  • Patent number: 8152808
    Abstract: The invention is directed toward a surgical kit having component parts capable of use in excising a cartilage defect site on a patient to prepare the same for receipt of an implant plug, the kit comprising a cylindrical gauge with a central bore used to measure the defect area, a guide rod adapted to be driven through the gauge tube into the center of said defect area and a cartilage cutting assembly adapted to be mounted over the guide rod and used for excising the defect area and cutting a cylindrical bore into the defect area. The method for use of the kit comprises the steps of: marking the defect area to be cut; placing a guide rod into the center defect area and driving the same to a predetermined distance to secure the same in the defect area and placing a drill bit over the guide rod and rotating the drill bit to cut a cylindrical blind bore removing the cartilage defect.

  • Publication number: 20080109037
    Abstract: A sterile suture anchor and insertion kit with the suture anchor having a cylindrical body portion with a generally tapered distal end portion and flat end. A plurality of parallel longitudinal grooves are cut into the cylindrical body and a connecting throughgoing bore is cut through the cylindrical body engaging the plurality of longitudinal grooves. An inserter driver is adapted to be mounted to the suture anchor, the driver comprising a handle with a drive shaft mounted to the handle, and a slidable sleeve mounted on the drive shaft which holds the suture anchor. A guide member comprising a handle with a hollow sleeve extending therefrom is used to hold a punch against the area on which a blind bore is formed to form the blind bore after which the inserter driver is mounted in the guide member sleeve to guide the slidable sleeve of the inserter driver and associated suture anchor into the blind bore.

  • Publication number: 20080109038
    Abstract: A sterile suture anchor and drive kit with the suture anchor having a cylindrical body portion with a generally tapered distal end portion and a screw thread extending along a cylindrical body portion. A plurality of parallel longitudinal grooves are cut into the cylindrical body interrupting opposed portions of the screw thread and a connecting groove is cut through the distal end portion of the suture anchor engaging the plurality of longitudinal grooves. A closed suture loop is mounted in the longitudinal grooves and the connecting groove. A driver is adapted to be mounted to the suture anchor, the driver comprising a handle with a tube mounted to the handle, the tube being provided with outwardly extending drive tip members adapted to be inserted into the suture anchor longitudinal grooves to engage the groove side walls of the suture anchor to apply driving torque to the suture anchor.
