1. An implant for restoring a height within a space between adjacent superior and inferior vertebrae of a spine, comprising: an expandable outer surface component formed of a biologically compatible material defining an inner fillable cavity, the outer surface component being expandable from a first configuration to a second expanded configuration when the inner cavity is filled with a filling material, the outer surface component having slightly curved generally planar upper and lower surfaces, said surfaces having an edge, and said surfaces joined circumferentially by the edge to an intermediate edge surface to form a generally bean-shaped implant when expanded in the second configuration, wherein the upper and lower surfaces of the implant in the second configuration are shaped and sized to be located entirely within the space between the adjacent superior and inferior vertebrae, and wherein the space extends from a recess surgically created in an inferior surface of the superior vertebra to a recess surgically created in a superior surface of the inferior vertebra, wherein the intermediate edge surface includes a plurality of multi-coil spiral outwardly extending ribs and further comprising a lead coiled between adjacent ribs.
