the second configuration comprising;
(i) the third longitudinal axis of the second portion of the linkage positioned non-parallel and non-colinear to said first longitudinal axis of the first member; and
wherein said transition between the first configuration and the second configuration produces movement of said linkage relative to said first member, said movement comprising;
(i) a rotation of said first portion of the linkage around the axis that extends from said first top surface to said opposing first bottom surface of the first member; and
(ii) a translation of the first portion of the linkage within said first internal channel of the first member.

Abstract
Apparatus and methods for providing spinal percutaneous delivery of an implant that can rigidly fixate the spinous process of a first superior bone and a second inferior bone of a functional spinal unit. In one aspect, the device comprises two bone abutment members connected via an interconnecting member. In another aspect, the method comprises implanting at least two spinal implant apparatus within a target disc space via an implantation apparatus. In another aspect, a placement instrument comprising an implant delivery segment, an anchor segment, and an articulating arm is disclosed.
