  • Synthetic polyurethane composite
    Patent number: 9801946
    Abstract: Embodiments of the present inventions comprise composites of polyurethane(s), osteoconductive matrix, and, optionally, a growth factor. Embodiments further comprise methods of making such composite and uses thereof. The osteoconductive matrix can be a tricalcium phosphate, bioglass, or the like, and can include particles that are surface modified. Growth factors can be provided in powder form, including bone morphogenic proteins such as rhBMP-2. A composition may be moldable and/or injectable. After implantation or injection, a composition may be set to form a porous composite that provides mechanical strength and supports the in-growth of cells.
    Type: Grant
    Filed: April 22, 2013
    Date of Patent: October 31, 2017
    Assignee: Vanderbilt University
    Inventors: Scott A. Guelcher, Jerald Dumas, Edna M. Prieto, Anne Talley, Andrew Harmata, Katarzyna Zienkiewicz
