Abstract:
1. An expandable spinal implant comprising: a first member having first and second arms, the first and second arms of the first member both including an upper face partially defining an upper contact area of the implant and a lower face partially defining a lower contact surface of the implant; and a second member having first and second arms, the first and second arms of the second member both including an upper face partially defining an upper contact area of the implant and a lower face partially defining a lower contact surface of the implant, the second member being completely separate from the first member; the first and second members coupled to each other such that the first and second arms of the first member alternate with the first and second arms of the second member, the first and second members pivotally coupled to each other for relative movement about a rotation axis between a closed position for inserting the implant into a spine and an expanded position for providing structural support to the spine, the rotation axis extending generally perpendicular to the upper and lower contact surfaces, wherein the first and second members both include a central portion between the respective first and second arms, the central portions of the first and second members being rotatably coupled.
