  • Patent number: 11617588
    Abstract: A device for collecting a bone graft material comprises a canister extending defining a filter-receiving space therein, the canister including a connection for connecting to a vacuum source, a proximal end of the canister including a first locking feature and a filter element sized and shaped to be received within the filter-receiving space of the canister, the filter element including a channel extending therethrough, the channel defined via a mesh material and a proximal end of the filter element including a second locking feature releasably engageable with the first locking feature of the canister via a rotation of the filter element about a longitudinal axis thereof relative to the canister in combination with an extractor sized and shaped to be received within the channel of the filter element, the extractor defining a graft material receiving space therein and being releasably engageable with the extractor.

  • Publication number: 20220202992
    Abstract: The present disclosure is directed to a method of preparing an osteogenic bone graft. The method includes introducing an anticoagulant compound into a volume of cellular material including a mononuclear cell population from the intramedullary canal of a long bone; collecting an effluent including the volume of cellular material containing the anticoagulant compound at a collection point; separating a concentrated cell fraction from the effluent, the concentrated cell fraction including the mononuclear cell population and the anticoagulant compound; and preparing an osteogenic bone graft from the concentrated cell fraction.

  • Patent number: 8852119
    Abstract: A bone marrow harvesting device includes a flexible bone marrow harvesting needle that can bend during operation to prevent the needle tip from piercing the inner cortical wall of the target bone. The needle defines an aspiration channel that defines an intake end that is recessed to reduce the instances that the aspiration channel will be fouled by bone particles or other debris within the cancellous portion.

  • Patent number: 8057595
    Abstract: The present invention relates in general to implantable compositions, and method for preparing same, containing a calcium salt-containing component, optionally demineralized bone, a plurality of discrete fibers, optionally a flow additive, and optionally continuous reinforcing fibers or an array of organized fibers in the form of mesh. Advantageously, the discrete fibers have a specific aspect ratio (length/diameter) from about 50:1 to about 1000:1. The addition of a small amount of discrete fibers and/or the continuous reinforcing fibers or fiber mesh can cause drastic increases in certain mechanical properties including flexural strength, flexural toughness, and/or screw pullout strength.
