Abstract
A device is disclosed for insertion in the human or animal body in order to increase the spacing between adjacent spinous processes of the spinal column. The device comprises a plurality of shaped members which are pivotally joined to each other and arranged around a central screwed rod which is supported by a collar at one end and a threaded collar at the opposite end said collar and collar being located within the pivoting axis of the adjacent members forming each end of the device. Following insertion in the body and positioning between adjacent spinous processes the device may be deployed by rotation of the central screwed rod in order to achieve the desired separation of adjacent spinous processes while at the same time providing a secure location of the device in the deployed condition.
