  • 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.
