  • Patent number: 10300167
    Abstract: The present invention provides a functionalized composition and resulting functionalized body or prosthesis for in vitro and in vivo use comprising at least one calcium phosphate containing phase that is functionalized with a linker group comprising at least one of an organic acid molecule, a phosphonic acid, an amine, N,N-dicyclohexylcarbodiimide, and 3-maleimidopropionic acid N-hydroxysuccinimide ester, and combinations thereof, and one or more of a chemical and/or a biologically active moieties, wherein the linker group provides for a reactive location for the attachment of the chemical or biologically active moiety, or both, to the calcium phosphate containing phase, and optionally including an unmodified and/or modified calcium aluminate containing phase. Methods of manufacturing a functionalized artificial prosthesis and methods of repairing a bone, vertebrae, or tissue structures are provided.
    Type: Grant

    Assignees: CAberTech, Inc., Duquesne University of the Holy Spirit
    Inventors: Kenneth A. McGowan, Ellen S. Gawalt, Rachelle Palchesko
  • Patent number: 8535706
    Abstract: A bone implant, and bone implant material, includes a calcium- and oxide-containing artificial graft material in a scaffold, to which melatonin and an optional cell adhesion peptide are absorbed or covalently linked.
    Type: Grant

  • Publication number: 20130029960
    Abstract: The combined use—whether by adsorption or covalent linkage—of Melatonin adjacent any bone implant or graft, preferably any calcium- and oxide-containing artificial bone graft material, and more preferably a calcium aluminate composition. Alternatively, the bone graft or implant material may be used as a scaffold for tissue engineering.

  • Publication number: 20120087950
    Abstract: The present invention provides a functionalized composition and resulting functionalized body or prosthesis for in vitro and in vivo use comprising at least one calcium phosphate containing phase that is functionalized with a linker group comprising at least one of an organic acid molecule, a phosphonic acid, an amine, N,N-dicyclohexylcarbodiimide, and 3-maleimidopropionic acid N-hydroxysuccinimide ester, and combinations thereof, and one or more of a chemical and/or a biologically active moieties, wherein the linker group provides for a reactive location for the attachment of the chemical or biologically active moiety, or both, to the calcium phosphate containing phase, and optionally including an unmodified and/or modified calcium aluminate containing phase. The functionalized compositions have a pliable physical property when mixed with water and adhere to natural bone and subsequently harden at ambient temperatures.
