  • Publication number: 20210322186
    Abstract: An implant device for use in achieving spinal fusion, includes an implant having an implant body. The device includes a graded radiopacity calibration tool integrated with the implant body. The tool has a plurality of graded levels of radiopacity representative of a range of bone density parameter amounts. Each of the graded levels corresponds to a different bone density parameter amount. A method is provided that uses the device to determine a degree of one of bone maturity, strength, osteoporotic state, state of healing and state of degrading bone tissue based on a comparison of a bone at the site in the image and radiopacity correlated from a calibration standardized curve defined by the standard, with a range of grey levels representative of degrees of one of the bone maturity, the strength, the osteoporotic state, the state of healing and the state of degrading bone tissue.

  • Patent number: 11145415
    Abstract: A system including a range of motion module, a quality of sleep module, an overall module, and a control module. The range of motion module, subsequent to performing a procedure on a patient, determines a first range of motion score of the patient based on a signal generated by a sensor. The quality of sleep module, subsequent to performing the procedure on the patient, determines a first quality of sleep score or a first pain score based on the signal generated by the sensor. The overall module determines a combined score based on (i) the first range of motion score, and (ii) the first sleep score or the first pain score. The control module (i) determines whether an outcome of the procedure is positive based on the combined score, and (ii) stores the determined outcome and the combined score in a memory.

  • Patent number: 11136550
    Abstract: Methods of decontaminating bone tissue and an apparatus or system for the same are provided. The methods can be multi-batch processes and include contacting the bone tissue having contaminants with carbon dioxide to decontaminate the bone tissue and to form carbon dioxide having contaminants. The contaminated carbon dioxide is collected and the contaminants are removed to obtain purified carbon dioxide which can be recycled to treat contaminated bone tissue. The contaminated carbon dioxide can be purified by bubbling it through water and/or an organic solvent followed by acid treatment, filtering and liquefying the carbon dioxide. Contaminants that can be removed from contaminated bone tissue, and in turn, from contaminated carbon dioxide include infectious organisms, bacteria, viruses, protozoa, parasites, fungi and mold or a mixture thereof.

  • Patent number: 11135071
    Abstract: A geared cam expandable spinal implant. Rotational motion of a rotating portion is translated into linear motion of a yoke, which moves geared cams at the distal end of the implant to mate with, and walk along, teeth of corresponding racks. The walking of the gear cam teeth along the rack teeth creates a regular rate of implant expansion, reduces initial excessive expansion force applied to the implant, and provides fine adjustment of the expansion rate and force. Spikes, pivotally mounted on the yoke, pivot outward as the implant expands, to a fully-deployed position into engagement with surfaces of adjacent vertebral bodies. The engagement between the deployed spikes and the vertebral bodies prevents inadvertent backout of the expanded implant.
