  • Patent number: 10357511
    Abstract: Osteoinductive compositions and implants having increased biological activities, and methods for their production, are provided. The biological activities that may be increased include, but are not limited to, bone forming; bone healing; osteoinductive activity, osteogenic activity, chondrogenic activity, wound healing activity, neurogenic activity, contraction-inducing activity, mitosis-inducing activity, differentiation-inducing activity, chemotactic activity, angiogenic or vasculogenic activity, and exocytosis or endocytosis-inducing activity. In one embodiment, a method for producing an osteoinductive composition comprises providing partially demineralized bone, treating the partially demineralized bone to disrupt the collagen structure of the bone. In another embodiment, an implantable osteoinductive and osteoconductive composition comprises partially demineralized bone, wherein the collagen structure of the bone has been disrupted, and, optionally, a tissue-derived extract.

  • Patent number: 10328179
    Abstract: An osteoinductive composition, corresponding osteoimplants, and methods for making the osteoinductive composition are disclosed. The osteoinductive composition comprises osteoinductive factors, such as may be extracted from demineralized bone, and a carrier. The osteoinductive composition is prepared by providing demineralized bone, extracting osteoinductive factors from the demineralized bone, and adding the extracted osteoinductive factors to a carrier. Further additives such as bioactive agents may be added to the osteoinductive composition. The carrier and osteoinductive factors may form an osteogenic osteoimplant. The osteoimplant, when implanted in a mammalian body, can induce at the locus of the implant the full developmental cascade of endochondral bone formation including vascularization, mineralization, and bone marrow differentiation. Also, in some embodiments, the osteoinductive composition can be used as a delivery device to administer bioactive agents.

  • Patent number: 10220115
    Abstract: Bone matrix compositions having nanoscale textured surfaces and methods for their production are provided. In some embodiments, bone matrix is prepared for implantation and retains nanoscale textured surfaces. In other embodiments, nanostructures are imparted to bone matrix wherein collagen fibrils on the surface of the bone matrix have been compromised, thus imparting a nanoscale textured surface to the bone matrix. Generally, these methods may be applied to mineralized or demineralized bone including partially or surface demineralized bone.

  • Patent number: 10028837
    Abstract: A covering for delivering a substance or material to a surgical site is provided. The covering, with substance provided therein, may be referred to as a delivery system. Generally, the covering may be a single or multi-compartment structure capable of at least partially retaining a substance provided therein until the covering is placed at a surgical site. Upon placement, the covering may facilitate transfer of the substance or surrounding materials. For example, the substance may be released (actively or passively) to the surgical site. The covering may participate in, control, or otherwise adjust, the release of the substance.

  • Patent number: 9855368
    Abstract: A cyclized peptide designated BMP Binding Peptide (BBP) is a synthetic peptide that avidly binds rhBMP-2, as do endogenous forms of BBP, and sequence conservation between species results in a variety of useful BBP compositions. BBP increases the over-all osteogenic activity of rhBMP-2, increases the rate at which rhBMP-2 induces bone formation, and BBP induces calcification alone. Compositions and substrates including BBP, and methods of using BBP are useful in therapeutic, diagnostic and clinical applications requiring calcification and osteogenesis.

  • Patent number: 9694047
    Abstract: The use of autogenous bone graft is the current gold standard in the 1.5 million bone-grafting surgeries performed annually in the United States. Although this practice has resulted in high rates of fusion success, it is associated with increased operative time and blood loss, along with a significant degree of donor-site morbidity. Additionally, in certain settings such as revision cases, multilevel constructs, or in patients with medical co-morbidities, autogenous bone graft may exist in limited quantity and quality. This significant need for a suitable alternative to autogenous bone graft has stimulated great interest in the exploration of bone graft substitutes and extenders.

  • Patent number: 9415136
    Abstract: 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.
