Patent ID: 8197514

Claim:
An implant for mutual support of the spinous processes of two adjacent vertebral bodies with an upper support surface for the spinous process of an upper vertebral body and a lower support surface for the spinous process of a lower vertebral body, the spacing between which can be increased, wherein it comprises two implant components, each of which having at least two adjacent support arms, which are connected to one another at one end by means of a bridge and can be spread apart at their free ends, and at least one of which support arms forms one of the support surfaces, with the free ends of their support arms both implant components are directed towards the free ends of the support arms of the respective other implant component, and both implant components slide on slide faces of the respective other implant component, and are pivoted thereby, so that the spacing of the upper and lower support surfaces is thereby increased, wherein the support arms of one implant component run inclined relative to one another, starting from the bridge connecting them, that they cross over one another and that the support arms slide on the slide faces of the other implant component with their outer surfaces and are thereby inclined even more steeply relative to one another, wherein as a result of the crossover of the support arms the free ends of the support arms are moved away from one another.
