Patent ID: 7811311

Claim:
A medical device for supporting one or more bones comprising: a screw assembly including: a screw having an anchor configured for insertion into bone, a base head, and a base coupled between the anchor and the base head, where the base head includes a receiver defining an aperture opening at opposite sides of the receiver and the aperture further opening at a proximal end of the receiver and a locking device in engagement with the receiver in the proximal end opening of the aperture, and one or more arms extending along a longitudinal axis, said one or more arms include an offset section extending through one of the side openings of the aperture of the receiver with the offset section rotatably attached to the base head, the offset section extending to a body so that the one or more arms are rotatable from a first position where the body and the longitudinal axis are substantially co-axially aligned with a long axis of the base to a second position where the body and the longitudinal axis are substantially perpendicular to the long axis of the basis while the offset section extends from the base head in offset relation to the long axis and the longitudinal axis, wherein the locking device is movable into the receiver through the proximal end opening of the aperture to contact the offset section in the receiver of the base head, where each arm of the one or more arms is configured to directly connect to a support structure having an anchor at a first end configured for insertion into bone.
