  • Patent number: 8328876
    Abstract: The present invention provides methods of improving the osteogenic and/or chondrogenic activity of a bone matrix, e.g., a dermineralized bone matrix (DBM), by exposing the bone matrix to one or more treatments or conditions. In preferred embodiments the bone matrix is derived from human bone. The treatment or condition may alter the structure of the bone matrix and/or cleave one or more specific proteins. Cleavage may generate peptides or protein fragments that have osteoinductive, osteogenic, or chondrogenic activity. Preferred treatments include collagenase and various other proteases. The invention further provides improved bone and cartilage matrix compositions that have been prepared according to the inventive methods and methods of treatment using the compositions. The invention further provides methods of preparing, testing, and using the improved bone matrix compositions.

  • Publication number: 20120259426
    Abstract: The present invention is a new composite bone graft material made from biocompatible poly(D,L-lactic-co-glycolic acid) (PLGA) and nano-sized hydroxyapatite particles exposed on its surface using a gas foaming particle leaching (GF/PL) method. A further embodiment of this invention involves coating this PLGA/hydroxyapatite biomaterial with an adherent, fast, uniform coating of a mineral such as apatite. The PLGA polymer portion of the composite provides sufficient mechanical strength to replace bone and is degradable over time to allow new bone tissue ingrowth. The incorporated hydroxyapatite particles increase the composite material's osteogenic properties by providing sites for tissue attachment and propagation. Finally, a uniform coating of mineral apatite on the surface of this novel biomaterial composite further enhances its osteogenic qualities.

  • Patent number: 8273194
    Abstract: This invention discloses a method, using pure niobium as a transient liquid reactive braze material, for fabrication of cellular or honeycomb structures, wire space-frames or other sparse builtup structures or discrete articles using Nitinol (near-equiatomic titanium-nickel alloy) and related shape-memory and superelastic alloys. Nitinol shape memory alloys (SMAs), acquired in a form such as corrugated sheet, discrete tubes or wires, may be joined together using the newly discovered joining technique. Pure niobium when brought into contact with nitinol at elevated temperature, liquefies at temperatures below the melting point and flows readily into capillary spaces between the elements to be joined, thus forming a strong joint.

  • Patent number: 8012218
    Abstract: There is disclosed a bone substitute material for medical use which satisfies all the requirements of (1) no histotoxicity, (2) osteoconductivity, (3) bone replacement capability, and (4) mechanical strength necessary for a bone reconstruction operation. The bone substitute material for medical use is predominantly composed of carbonate apatite and produced through the formation of carbonate apatite by contacting a block of calcium compound with a phosphate-containing solution, wherein the calcium compound block contains substantially no powders, and at least one of said calcium compound block and said phosphate solution contains a carbonate group, without any sintering. The block of calcium compound is preferably one prepared using an artificially synthesized calcium compound, most preferably a foamed calcium compound.

  • Patent number: 7998207
    Abstract: Interbody fusion implants that include a load bearing body composed of a calcium phosphate material hardened around one or more structural reinforcing members are provided. The reinforcing members aid the load bearing body in resisting bending forces and, in certain forms, aid in preventing expulsion of the implant after implantation. Methods for promoting fusion bone growth in the space between adjacent vertebrae and methods for making the inventive implants are also provided.

  • Publication number: 20110160870
    Abstract: An implant system includes a fixation device that, in turn can include an expandable implant alone or in combination with an auxiliary implant. The expandable implant includes an expandable implant body that is made from an expandable material. The expandable material includes a polymer matrix and an expandable gas source contained within at least a portion of the polymer matrix. The implant system can further include an energy source configured to heat the polymer matrix to a temperature above its glass transition temperature, thereby causing the gas source to expand inside the polymer matrix. The fixation device can further include an insertion instrument configured to implant the fixation device into an anatomical cavity.

  • Publication number: 20110153029
    Abstract: The present invention concerns a process for the preparation of a flexible composite membrane, biocompatible and biodegradable, obtained from natural or synthetic materials, containing inorganic osteoconductive elements with a gradient of concentration along the thickness of the membrane or an asymmetric concentration of such elements in both sides of the membrane. The membrane may be obtained by gravitational deposition of the osteoconductive elements during solvent evaporation. The membrane is aimed to be used in vivo, in guided tissue regeneration, as a sealant for defects or structures for tissue engineering, or as coatings for biomaterials. The membrane exhibits one side featuring osteoconductive properties, that interacts favorably with mineralized tissues or other implanted bioactive materials, and the other side prevents the penetration or invasion of other tissues.

  • Publication number: 20110144763
    Abstract: The present disclosure relates to a dynamic bioactive bone graft material having an engineered porosity. In one embodiment, a bone graft material is provided having bioactive glass fibers arranged in a porous matrix that is moldable into a desired shape for implantation. The material can be substantially without additives and can include at least one nanofiber. The porous matrix may include a combination of one or more pore sizes including nanopores, macropores, mesopores, and micropores. In another embodiment, a bone graft implant is provided having a matrix comprising a plurality of overlapping and interlocking bioactive glass fibers, and having a distributed porosity based on a range of pores provided in the bioactive glass fibers. The distributed porosity can comprise a combination of macropores, mesopores, and micropores, and the matrix can be formable into a desired shape for implantation into a patient.

  • Publication number: 20110144764
    Abstract: The present disclosure relates to a bone graft material and a bone graft implant formed from the material. In some embodiments, the bone graft implant comprises a porous matrix having a plurality of overlapping and interlocking bioactive glass fibers and a plurality of pores dispersed throughout the matrix, whereby the fibers are characterized by fiber diameters ranging from about 5 nanometers to about 100 micrometers, and the pores are characterized by pore diameters ranging from about 100 nanometers to about 1 millimeter. The implant may be formed into a desired shape for a clinical application. The embodiments may be employed to treat a bone defect. For example, the bone graft material may be wetted and molded into a suitable form for implantation. The implant may then be introduced into a prepared anatomical site.
