  • Patent number: 8361126
    Abstract: Bone plate systems for surgical implants and bone repair are provided. The bone plate is multi-tiered for receiving bone anchors for securing a plurality of bones or bone fragments in a desired relationship. The plate members include throughbores for receiving a pivot base therein, with head ends of the bone anchors being secured within the pivot bases. The throughbores may permit and define a translation path for the pivot base and the bone anchor secured therein relative to the plate. The configuration of the pivot base and the throughbore facilitate pivoting and optional translation of the pivot base relative to the plate. With the bone anchor seated within the pivot base, an apparatus for inhibiting bone anchor back out is employed.

  • Patent number: 8361153
    Abstract: An intervertebral space distraction and implantable device assembly provides sequentially axially wider spacers that are to be sequentially inserted into and removed from an intervertebral space to widen the space until a desired anatomical spacing of the adjacent vertebral bones is restored. The set of spacers includes a porous spacer that is as wide as the spacer that restores the desired anatomical spacing. The porous spacer can therefore be left implanted in the intervertebral space to promote fusion of the adjacent vertebral bones.

  • Patent number: 8361080
    Abstract: A spinal implant insertion tool, comprising: a) a shaft having distal end having upper and lower pairs of prongs extending therefrom, the prongs adapted for holding an implant or an implant trial and defining a centerline therebetween, and b) an adjustable stop slidably received upon the shaft of the tool, wherein the adjustable stop has a bifurcated distal end defining first and second prongs that are off-centerline from the centerline. Because the stop is bifurcated and thereby avoids the centerline of the vertebral bodies, it will not collide with components of a Caspar distractor.

  • Patent number: 8357164
    Abstract: A surgical punch has a cartridge for collecting the resected chips cut off in successive punch cuts. The cartridge is a replaceable disposable commodity. The cartridge consists of a casing and a tooth rail which is guided longitudinally displaceable relative to the casing. Once the cartridge is inserted, the casing is fixed on the upper part of the punch, while the tooth rail is fixed on the lower part of the punch. A transport serration is formed in the casing. The tooth rail has a retaining serration. During the opening and closing movement of the punch, the transport serration and the retaining serration interact as transport mechanism which displaces the cut off resected chips in the cartridge in the proximal direction.

  • Patent number: 8348952
    Abstract: A device and method of correcting a spinal defect in a patient employs the use of shape memory material in a spinal correction device. The shape memory material may be transitioned between a flexible martensitic state to allow shaping of the spinal correction device and a rigid austenitic state to apply corrective forces to the spine. The shape memory material may be transitioned to the flexible martensitic by applying a coolant, such as cold gas, directly or indirectly to the shape memory material to transfer heat away from the material. The cooling device and method may allow for in-vivo shaping of the spinal correction device while inserted in the body and attached to bone anchors by cooling the spinal correction device after insertion.

  • Patent number: 8348983
    Abstract: A surgical bone screw includes an elongate body having a proximal end, a distal end, a threaded portion on the circumference of the body, and a passage extending between the proximal and the distal ends of the body. An electrical conductor is disposed in the passage between the proximal and the distal ends of the screw body. The conductor has a first terminal at the proximal end and a second terminal at the distal end. The conductor and both of the terminals are electrically insulated from surrounding portions of the screw body. When the screw is driven into bone tissue and a stimulating current is applied to the first terminal, the current is directed substantially through the conductor to flow into tissue adjacent to the second terminal at the distal end, without shunting by other tissue that surrounds the screw body.

  • Patent number: 8333767
    Abstract: A cerclage device includes a base member, a cerclage member, and a drive member. The base member has a length sufficient to allow for manual holding by a user, an interior space extending from a distal end toward a proximal end, and a slot extending from the distal end toward the proximal end. The cerclage member has a long side with a proximal end and a distal end and a curvature in one direction about its long side at least at the distal end. The cerclage member allows for attaching a suture and fits within and is straightened by the base member within the interior space when in a retracted position. When the drive member is attached to the cerclage member movement of the engagement portion in the slot pushes and pulls the cerclage member to/from the straightened position from/to the extended curved position.
