  • Publication number: 20060211953
    Abstract: Surgical instruments for use in mapping tissue defects include telescoping rulers and tubes. One of the instruments has a pointed anchoring tip for piercing tissue near the site of the defect. Another instrument has a hook for catching an anatomical landmark. Measuring portions of the rulers of both instruments include distance indicia so that a coordinate system can be established for mapping the location of the defect or of an implant at the defect site. The coordinate system can be re-established at a later time using the same fixation point for the anchoring tip and the same landmark for the hook to evaluate the clinical effects of the treatment selected. The method of using the instrument set is also described.

  • Publication number: 20060095053
    Abstract: A cannula has a flange and a body with slots extending through the entire flange and into the body. The cannula may also have a longitudinal slot extending its entire length. An obturator used with the cannula may also have a longitudinal slot extending along its length. A surgical method using these instruments includes separating lengths of suture and managing the suture by placing lengths of suture in the slots in the cannula. The cannula and obturator may be used after suture is already in place by placing the suture in the longitudinal slots and then introducing the cannula and obturator to the tissue defect site. The cannula may also be used to deliver a therapeutic implant to the tissue defect site. The instruments and method may be used in mensical surgery.

  • Publication number: 20060095049
    Abstract: Surgical instruments for use in sizing tissue defects and selecting an appropriate implant for the defect include sizing templates. The sizing templates are sized and shaped to correspond to the size and shape of the implants. The sizing templates may be retractable into a tube for use in arthroscopic surgery. The retractable sizing templates are resilient to allow them to be retracted into a small diameter tube, and to expand on release from the tube to the desired size and shape. The method of using the instrument set is also described.

  • Patent number: 7014640
    Abstract: A dispensing device for granule bone graft of varying and/or irregular shape is characterized by a body defining a handle/hopper portion, a dispensing portion, and a feed system. The subject device permits reloading or refilling of bone graft at the time of use of the device. The bone graft dispensing device also accepts vials of bone graft. The vials are loaded onto and releasably retained by the dispensing device. In both forms, the feed system allows a controlled and/or variable rate of flow of bone graft during dispensing. The subject device may be made disposable as well as re-usable. The subject device is also modular in design allowing easy assembly/disassembly. The is subject bone graft dispenser is particularly suited for the dispensing of dry, particulate and/or granule bone graft. Particularly, the bone graft dispensing device is especially suited for the dispensing of particulate or granule bone graft having particulates or granules of various and/or irregular size, shape and combinations thereof.

  • Publication number: 20050137600
    Abstract: A technique for the arthroscopic delivery and fixation of an articular cartilage repair device or implant is provided. The technique includes the use of a cannula tube that functions as both a cartilage cutter and a guide to pass instruments into the body arthroscopically. One such instrument is an end-cutting reamer that both prepares the subchondral bone by re-surfacing it down to a specified depth and also simultaneously drills a pilot hole in the subchondral bone to accept the cartilage repair device. A delivery device is utilized to hold and deliver the cartilage repair device to the delivery site.
