  • Patent number: 6830763
    Abstract: The invention is directed to a process for producing demineralized osteoinductive bone, and demineralized osteoinductive bone produced thereby. The process achieves demineralization of bone by subjecting bone, including for example ground bone, bone cubes, chips, strips, or essentially intact bone, to a rapid continuous acid demineralization process. The process includes subjecting bone to a continuous exchange of demineralizing acid solution where the demineralizing acid solution is recirculated from the substantially closed container through an ion exchange media to remove calcium and phosphate thereby producing a regenerated acid, and returning the regenerated acid to the substantially closed container to produce osteoinductive demineralized bone. The process allows bone to be rapidly demineralized to a precise and specific desired residual calcium level, without sacrificing osteoinductivity.

  • Publication number: 20040062816
    Abstract: A bone repair material is described that is of putty-like consistency, particularly useful for repairing dental bony defects such as those caused by bone loss resulting from moderate or severe periodontitis, augmenting of bony defects of the alveolar ridge, filling tooth extraction sites, or sinus elevation grafting. The repair material includes a porous, resorbable particulate that is bone-derived or derived from bone-like hydroxyapatite or synthetic hydroxyapatite; and, a resorbable carrier, such as high molecular weight polysaccharides, such as hyaluronic acid. A high concentration of particulate in the putty enhances bone repair and requires a high concentration of carrier to retain the putty at the defect site. For a particulate density of about 1.2 g/cc such as PEPGEN P-15® Bone Graft, a preferred formulation comprises about 55% percent by weight of the putty suspended in a hyaluronic acid gel of about 1.

    Abstract: For the repair of injured bone or cartilage, an oxygen enriched material is formed with a high-level (partial pressure) and amount (volume) of dissolved oxygen to support tissue healing. The oxygenated material can be placed in a container having an air valve and pressurized in the container with oxygen to supersaturate the material. The resulting container can be sterilized and transported for use. Immediately prior to use, the valve can be operated to vent the pressure in the container thereby facilitating access to the material. The material can then be applied directly to the hard tissue injury. Absorption of the oxygen to facilitate healing can be enhanced with the use of ultrasonic energy. An oxygen inhibiting film can be placed over the material to direct the oxygen toward the wound.

  • Patent number: 6417166
    Abstract: A strong, thin flexible mineralized collagen membrane is disclosed that is useful for such medical applications as a barrier for guided tissue regeneration, periodontal defect repair, bone grafts and skin wound repair. The mineralized collagen membrane comprises a substantially homogeneous mineralized collagen composite consisting essentially of about 30% to about 70% by weight of a collagen component and about 30% to about 70% by weight of a calcium phosphate minerals component precipitated from a collagen slurry by a soluble calcium ion-containing solution and a soluble phosphate ion-containing solution. The calcium phosphate minerals component has a mole ratio of calcium to phosphate in the range of about 1.0 to about 2.0. The thin mineralized collagen membrane has a bulk density of the membrane of at least about 1.0 g/cm3 and has a thickness not greater than about 0.5 mm and preferably not greater than about 0.3 mm.

  • Patent number: 6380366
    Abstract: The present invention relates to cartilage extracts and to a method of producing the same. Shark cartilage extracts having anti-angiogenic, anti-tumor, anti-inflammatory and anti-collagenolytic activities have been obtained by an improved process. The process comprises the steps of obtaining a crude cartilage extract in an aqueous solution, this crude extract being fractionated to recover molecules of a molecular weight less than about 500 kDa. Some of the biologically active components of the extract are prepared by further fractionation. The cartilage extract can be used for treating diseases or conditions having etiological components selected from the group consisting of tumor proliferation, angiogenesis, inflammation, metalloprotease activity and collagenolysis. Several cosmetic applications based on the capacity of the liquid extract to improve skin conditions are also disclosed. A simple and efficient process for the preparation of cartilage extracts is also disclosed.
