  • Patent number: 10137007
    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.

  • Patent number: 10080661
    Abstract: An osteoimplant composite comprising a plurality of particles of an inorganic material, a bone substitute material, a bone-derived material, or any combination thereof; and a polymer material with which the particles are combined. The composite is either naturally moldable or flowable, or it can be made moldable or settable. After implantation, the composite may be set to provide mechanical strength to the implant. The inventive composite have the advantage of being able to fill irregularly shape implantation site while at the same time being settable to provide the mechanical strength required for most orthopedic applications. The invention also provides methods of using and preparing the moldable and flowable composites.

  • Patent number: 10080559
    Abstract: A method facilitates the treatment of the spine of a patient by providing simultaneous access through at least a first opening and a second opening formed in the patient. For example, the method can include the acts of positioning the patient on a surgical table, providing the first opening into a posterior portion of the patient, providing the second opening into a lateral portion of the patient, inserting a first device through the first opening into the patient to contact the spine in a first direction that is transverse to the coronal plane of the patient, and inserting a second device through the second opening into the patient to contact the spine in a second direction that is transverse to the sagittal plane of the patient, where the first and second openings are accessible simultaneously, and, when the first and second devises are inserted into the patient, the position of the patient is stationary with respect to a portion of the table.
