Patent ID: 7947064

Claim:
A system for stabilizing a portion of a spine, comprising: a rod having: a non-circular cross-sectional profile a curvature along a length of the rod; and a recessed portion located along the length and oriented transverse to a longitudinal axis of the rod; two bone fastener assemblies, wherein each bone fastener assembly comprises: a pedicle screw for advancement into a vertebra; a collar for coupling the rod to the pedicle screw, comprising: two upwardly extending walls forming a passage having a profile for receiving a portion of the rod non-circular cross-sectional profile; and a threaded portion; and a threaded closure member for engaging the threaded portion of the collar to couple the rod in the passage; and a wire for percutaneous advancement of the rod to the passage in a bone fastener assembly coupled to a vertebra, wherein the wire comprises: a non-circular cross-sectional profile complementary to the rod non-circular cross-sectional profile for engaging the rod to inhibit rotational movement of the rod relative to the wire; and a cross-sectional profile and a curvature for engaging the recessed portion of the rod.
