Attorney, Agent or FirmInternational ClassA61M 031/100AbstractA process for removing essentially all bone marrow from a cut bone graft and the cut bone graft produced thereby. A large substantially intact bone is selected and excess cartilage and associated soft tissues are removed from the surface of the bone. The bone is left whole or may be cut into appropriate smaller pieces constituting cut grafts and bone marrow is removed from the cancellous bone spaces of the small cut grafts through the application of centrifugal force. Prior to and/or following the application of centrifugal force, the bone graft may optionally be pretreated with one or more decontaminating agents, and/or solubilizing agents. | |
