  • Patent number: 10137006
    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.

  • 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: 10070873
    Abstract: An orthopedic driver is provided that includes an elongate tubular body and an indicator assembly. The indicator assembly has a housing that has at least one opening and a visual indicator disposed in the at least one opening. The visual indicator is configured to be coupled with a guide pin such that lateral movement of the elongate tubular body relative to the guide pin causes the visual indicator to move between a flush or recessed configuration within the housing and an extended configuration. In the extended configuration, the visual indicator extends outward of an outer surface of the housing. The flush or recessed configuration corresponds to alignment of the guide pin relative to the elongate tubular body and the extended configuration corresponds to misalignment of the guide pin relative to the elongate tubular body.

  • Patent number: 10028843
    Abstract: A bone graft compaction pliers with removable inserts defines a bone graft harvesting and deployment system applicable to a wide variety of bone graft sized for use with bone anchors such as those employed in ACL repair. Cannulated bone anchors for encouraging bone regrowth employ an anchor with a axial cannulated bore and a plurality of fenestrations surrounding the bore to facilitate bone regrowth. A variety of sizes of single use inserts corresponding to a bone graft shape, or diameter, engage a single compaction pliers for forming various sized bone grafts from a single tool. A transparent transfer tube and corresponding base receives the formed bone graft for length adjustment, and engages protrusions on the recipient bone anchor for aligning the transfer tube to the anchor for disposing the bone graft into the cannulated bore of the anchor.
