Abstract

An expandable bone device including a unitary body extending along a longitudinal axis and including a deformable distal end portion having a collapsed orientation for placement adjacent a spinal structure, the deformable distal end portion including relatively wide, mutually contiguous support surfaces outlined by relatively narrow cutouts, the support surfaces being contiguous with the rest of the unitary body via relatively narrow deformable splines, the deformable distal end portion having an expanded orientation wherein the support surfaces are moved transversely outwards away from and generally parallel to the longitudinal axis, and an actuator coupled to the deformable distal end portion and operative to cause movement of the deformable distal end portion between the collapsed orientation and the expanded orientation.
