An intervertebral implant includes a chassis and endplates movable relative to the chassis. The endplates are each movable between a contracted position, wherein the endplates are nearer to a central axis defined relative to the chassis, and an expanded position, wherein the endplates are farther from the central axis. The chassis includes at least one wedge that, in turn, includes surfaces along which the endplates travel in transition between the contracted and expanded positions. The wedge remains stationary relative to the central axis throughout transitions between the contracted and expanded positions.

Stationary wedge expandable interbody device

An expandable device comprising, a body defining a bore, a shaft received in the bore of the body, an end plate coupled to the shaft, wherein rotation of the shaft translates the end plate with respect to the body, and a locking mechanism engaged with the shaft so as to permit the shaft to rotate in a first direction and apply a resistance force to resist the shaft when attempting to rotate in a second direction.

Expandable implant with worm gear

A spinal interbody implant includes a shaft extending along and rotatable about a central axis. The shaft includes a first threaded region. The implant further includes a first link having a first end with first gear teeth. The first end of the first link is fixed at a first point relative to the central axis such that the first gear teeth engage the first threaded region.
