The scaffold enhances the ability of osteoblasts to secrete organized collagen and mineralize extracellular matrix within the osteon-like channels, thus promoting scaffold strength.Type: ApplicationFiled: May 10, 2012Publication date: August 21, 2014Inventors: Mark R. Appleford, Marcello Pilia

Patent number: 8771748Abstract: Methods are provided for producing compositions, e.g. pastes or clays, which rapidly set into high-strength calcium phosphate products. In the subject methods, dry reactants that include calcium and phosphate sources, as well as a monovalent cation dihydrogen phosphate salt, are combined with a setting fluid and the combined reactants are mixed to produce the settable composition. A feature of the invention is that cements rapidly set into high strength product compositions. Also provided are the compositions themselves as well as kits for preparing the same. The subject methods and compositions produced thereby find use in a variety of applications, including hard tissue repair applications.Type: GrantFiled: May 19, 2005Date of Patent: July 8, 2014Assignee: Skeletal Kinetics, LLCInventors: Brent R. Constantz, David Delaney, Duran Yetkinler

Patent number: 8734525Abstract: An osteoinductive demineralized bone matrix, corresponding osteoimplants, and methods for making the osteoinductive demineralized bone matrix are disclosed. The osteoinductive demineralized bone matrix may be prepared by providing demineralized bone and altering the collagenous structure of the bone. The osteoinductive demineralized bone matrix may also be prepared by providing demineralized bone and compacting the bone, for example via mechanical compaction, grinding into a particulate, or treatment with a chemical. Additives such as growth factors or bioactive agents may be added to the osteoinductive demineralized bone matrix. The osteoinductive demineralized bone matrix may form an osteogenic osteoimplant. The osteoimplant, when implanted in a mammalian body, may induce at the locus of the implant the full developmental cascade of endochondral bone formation including vascularization, mineralization, and bone marrow differentiation.Type: GrantFiled: June 16, 2008Date of Patent: May 27, 2014Assignee: Warsaw Orthopedic, Inc.Inventors: Keyvan Behnam, Nanette Forsyth, James Russell, John Winterbottom, Todd Boyce
