  • Implant with structure allowing injection of polymer for attaching implant to tissue
    Patent number: 7361369
    Abstract: Methods and apparatus for bone implants that allow for the directed application of an osteogenic compound. The implant is preferably constructed of a biodegradable polymer formed into a structure having micro-architectural features and includes features that allow for in-situ application of a liquid biodegradable polymer to securely attach the implant to the surrounding tissue. The implant is constructed with a nozzle connected to a fluid supply that can be injected through a central channel and one or more distribution channels. The implant is designed so as to provide structural support to the damaged area. The implant and the fluid supply are preferably biodegradable polymers that contain an osteogenic material.
