Abstract: An example expandable interbody device can include a structural body having an upper endplate and a lower endplate. The device can include at least one wedge block and at least one linkage block arranged between the upper and lower endplates. The linkage block can include a plurality of linkages and a shear pin disposed at a respective proximal end of each of the linkages. The device can include a drive screw extending through the wedge and linkage blocks. The drive screw can be configured to rotate and drive the wedge block to expand the upper and lower endplates of the structural body from the closed position to an intermediate position. Additionally, the drive screw can be further configured to rotate and drive the linkage block to expand the upper and lower endplates of the structural body from the intermediate position to an open position.

Abstract: A seismic sway brace fitting for a seismic brace includes a first jaw defining a threaded opening configured to receive a fastener to secure the seismic sway brace fitting to the seismic brace, and a second jaw. A pin connects the first and second jaws to one another. The first and second jaws define a space configured to receive an end portion of the seismic brace. The threaded opening is aligned with the space such that the fastener extends into the space to engage the end portion of the seismic brace when the fastener is received in the threaded opening to secure the seismic brace to the sway brace fitting. The first jaw includes at least one brace bearing surface configured to engage an end of the seismic brace to inhibit the rotation of the first jaw relative to the second jaw.
