Abstract:
1. A device to space vertebral members comprising: a deploying device comprising: a first plate comprising a first surface and a second surface, the first surface engaging an upper side of the deploying device, the second surface comprising a plurality of planar angled ridges extending parallel to one another configured to engage tissue; a second plate comprising a first surface and a second surface, the first surface of the second plate engaging a lower side of the deploying device, the second surface of the second plate comprising a plurality of planar angled ridges extending parallel to one another; first, second, and third jointed linkages each comprising a pair of links and each having a first end attached to the first plate, a second end attached to the second plate, and an intermediate joint connecting the pair of links together and being attached to the deploying device, the intermediate joint of the first jointed linkage being attached to the first member at the first opening, the intermediate joint of the second jointed linkage being attached to the second member at the second opening, and the intermediate joint of the third jointed linkage being attached to the third member at the third opening; the first, second, and third members being nested together with the first distal section being axially movable relative to the second distal section between the first pair of arms to adjust a height measured between the first and second plates, and the second distal section being axially movable relative to the third distal section between the second pair of arms to adjust an angular orientation of the first and second plates.
