  • Patent number: 11278411
    Abstract: A method of creating a wedge-shaped recess in a bone is disclosed. The method includes creating a cylindrical recess within a bone, positioning a tool within the cylindrical recess, radially expanding an articulating cutter of the tool and rotating the tool to remove additional bone along the cylindrical recess' side walls and create a wedge-shaped recess; wherein, a diameter of the bottom surface of the wedge-shaped recess is larger than a diameter of a surface opening of the wedge-shaped recess.

  • Patent number: 10376368
    Abstract: According to some embodiments, a method of treating a joint of a patient comprises creating a recess in a bone located at or near a targeted joint, wherein the recess includes a generally wedge or truncated cone shape. In one embodiment, the recess in a bone comprises a surface opening along an outer surface of the bone and a bottom opening along the distal end of the recess, such that a diameter of the surface opening is generally smaller than a diameter of the bottom opening. The method additionally comprises providing a joint implant having a wedge or truncated cone shape, wherein a diameter of a top end of the joint implant is generally smaller than a diameter of a bottom end of the joint implant, inserting the joint implant within the recess.

  • Patent number: 7896920
    Abstract: Bioprosthetic devices include an exterior biological tissue member which at least partly defines a cavity, and a proteinaceous biopolymer which fills the cavity, and intercalates and is chemically bound (fixed) to the tissue of the surrounding biological tissue member. In preferred forms, the bioprosthetic device is a bioprosthetic vertebral disc having a fibrillar outer annulus which surrounds and defines an interior cavity and is formed by removal of at least a substantial portion of the natural gelatinous core therefrom. The cavity defined by the fibrillar outer annulus may then be filled with a flowable proteinaceous biopolymer. Preferably, the proteinaceous biopolymer is a liquid mixture comprised of human or animal-derived protein material and a di- or polyaldehyde, which are allowed to react in situ to form a cross-linked biopolymer within the cavity. The liquid mixture may be formed in advance of being introduced into the cavity, or may be formed simultaneously during introduction into the cavity.
