Patent ID: 8579907

Claim:
A device to space vertebral members comprising: a deploying device comprising: a first member comprising a first distal section; a second member comprising a second distal section including a first pair of arms each having an inner surface that engages an outer surface of the first distal section; and a third member comprising a third distal section including a second pair of arms each having an inner surface that engages an outer surface of the second distal section; a first plate comprising a first surface engaging an upper side of the deploying device; a second plate comprising a first surface engaging a lower side of the deploying device; and jointed linkages each comprising a first end attached to the first plate, a second end attached to the second plate, and an intermediate joint attached to the deploying device, a first intermediate joint being attached to the first member, a second intermediate joint being attached to the second member, and a third intermediate joint being attached to the third member, wherein the first distal section is 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 is movable relative to the third distal section between the second pair of arms to adjust an angular orientation of the first and second plates.
