Abstract
An expandable interbody spinal fusion device, including a superior component an inferior component and an expansion mechanism. The expansion mechanism including a threaded rod, a threaded collar operatively arranged to engage with the threaded rod and axially translate in a first axial direction, a fixed collar secured about the threaded rod, a first arm pivotably secured to the fixed collar, and a first strut pivotably secured to the first arm and the threaded collar.
