Abstract: A nested leaflet label structure having an enhanced information carrying capacity. The nested leaflet label structure includes a base panel having a front face. A first leaflet is adjacent to the front face and comprises a first folded panel having a first fold extending substantially parallel to the first axis of the label structure. The first fold divides the first folded panel into a pair of first leaves each having inner and outer page faces. A second leaflet comprises a second folded panel having a second fold extending substantially parallel to the first axis of the label structure. The second fold divides the second folded panel into a pair of second leaves each having inner and outer page faces. A laminating layer overlies the base panel and the first leaflet. The second leaflet is nested in the first leaflet. An assembling adhesive adheres the second leaflet to the first leaflet.

Abstract: A curved drill guide system for forming a channel in a vertebra of a patient for receiving a screw. The curved drill guide system includes an elongate handle member for being held by the hand. A mounting aperture extends through the handle member, with the mounting aperture having an axis oriented perpendicular to a longitudinal axis of the handle member. A guide member is provided for removably receiving and guiding the flexible drill bit. The guide member comprises a guide tube adapted for removably inserting into the aperture of the handle member. The guide tube has a base end and a free end and a length therebetween. A bore extends along the length of the guide tube and open at the base and free ends. The guide tube has an arcuate shape, with the arcuate shape being substantially uniform along the length of the guide tube.
