  • Patent number: 7744632
    Abstract: An apparatus for coupling a spinal rod to a cross bar comprising a main body having a channel with a wall for receiving a spinal rod therein, an opening for receiving a fastener with at least one tang adjacent to the opening, a clamping body pivotally disposed in the main body, the clamping body being moveable between a first position in which it does not clamp the spinal rod in the channel and a second position in which it does clamp the spinal rod in the channel, a cross bar having an opening aligned substantially with the opening of the main body and having the tang disposed therein, and a fastener for rigidly coupling the cross bar to the main body, the fastener being positioned within the openings of the cross bar and the main body, wherein the fastener is operable to force the tang into the cross bar to clamp the cross bar to the main body and simultaneously to move the clamping body between the first position and the second position.

  • Patent number: 7628799
    Abstract: The invention is a rod to rod connector that can be used to interconnect two generally parallel spinal rods of a spinal rod and anchor system. The connector comprises a transverse rod and two pairs of clamping bodies, one for each spinal rod. Each pair connects one of the longitudinal spinal rods to the transverse rod in infinitely adjustable angular relationship. One of the two clamping bodies of each pair comprises a C-shaped channel for accepting the spinal rod. The channel is in communication with a slot that defines a hinge. A threaded screw hole passes transversely through the slot and permits a screw to squeeze the hinge, thereby causing the C-shaped channel to close around and clamp the rod. The second clamping body is similar to the first except that there is no slot or hinge and the screw hole preferably is not threaded, but includes a countersink for seating a chamfered screw head. Also, an angular portion of the screw hole intersects the C-shaped channel.

  • Publication number: 20080132904
    Abstract: A surgical device suitable for use in spinal fusion of the cervical vertebrae is provided. The surgical device includes an inner tubular body and an outer tubular body. The inner and outer tubular body each has a lengthwise region and a distal portion with a discontinuous wall forming a fenestration. The fenestrations are alignable to provide a passage through the wall of the surgical device. The surgical device may provide any of several benefits, including unobstructed access to a surgical site, greater stability, and improved tactile control.
