    摘要: An anchoring device for attaching an upper vertebra adjacent to a lower vertebra comprises a clamp having a first end and a second end opposite the first end, adapted to be positioned around upper and lower lateral masses of the adjacent vertebrae, and a fastener which in an installed position engages opposite ends of the clamp and which engages adjacent vertebrae thereby attaching the adjacent vertebrae together.

    摘要: A cranial clamp for attaching a cranial flap to the skull comprises a clamp having a base to be placed against the lamina interna, and a cap acting as a locking member against the lamina externa. The clamp and the cap are linked together by an extension spring within the diploe through a burr hole or along/within the line of a craniotomy.

    摘要: A spinal plate system that allows for increased spinal stability is provided. In an embodiment, a spinal plate system is provided that includes first and second slidable plates coupled together. Each of the first and second slidable plates includes first and second fasteners that are obliquely oriented relative to the corresponding slidable plate. The first and second fasteners are fixed to each other at their distal ends thereby forming a triangular frame consisting of the corresponding slidable plate and the first and second fasteners. In addition, a fastener guide is provided that facilitates the accurate placement of the first and second fasteners for each of the first and second slidable plates.

    摘要: A novel ventricular catheter designed to reduce CSF shunt obstruction is disclosed comprising a tip using a membrane without any opening and capable of filtering the CSF. When the CSF flows through the membrane, neither tissue (choroid plexus, blood cells, tumor cells, suctioned ependymal tissue) nor proteins can break through the membrane, making this ventricular catheter capable of preventing obstruction from tissue invasion but also preventing clogging from protein precipitation, coagulation or flocculation along the downstream shunt system.
