  • Cancellous bone product including viable osteogenic cells
    Patent number: 11471560
    Abstract: A bone implant comprising cancellous bone that is essentially free of blood cells, and which has been treated with at least a loosening agent, such as collagenase and/or a digestive enzyme, for a time and at a concentration to loosen the osteogenic cells in the cancellous bone matrix.

  • Systems, devices, and methods for designing and forming a surgical implant
    Patent number: 11453041
    Abstract: A method is provided for determining the shape of a surgical linking device that is to be attached to a bony body structure such as the spinal column based on digitized locations of a plurality of attachment elements engaged to the bony structure. The method is implemented by a computer system through a GUI to generate an initial bend curve to mate with the plurality of attachment elements. The initial bend curve may be simplified based on user input to the GUI to reduce the number of bends necessary to produce a well-fitting linking device and may be altered to help obtain the goals of surgery.

  • Post-operatively adjustable angled rod
    Patent number: 11446063
    Abstract: A jointed rod assembly for use in a spinal fixation construct involves a caudal rod portion connectable to an adjustment mechanism, and a cranial rod portion connectable to the adjustment mechanism. The adjustment mechanism is configured to rotate the caudal and cranial rod portions relative to one another about a joint axis that is generally perpendicular to the longitudinal axes of the caudal and cranial rod portions. The caudal and cranial rod portions may be dimensioned to be compatible with other pieces of hardware commonly used for spinal fixation, such as bone anchors (e.g., pedicle screws), occipital plates, reducers, and others. The caudal and cranial rod portions are composed of a strong, rigid, non-absorbable, biocompatible material. The jointed rod assembly may be advantageously used in spinal fixation systems and methods of spinal fixation.
