Abstract
An implant, in particular an intervertebral prosthesis, which consists of an elongated elastic body which is form-elastic and takes on the form of a spiral S in the force free state. The spiral can be drawn by a reverse winding up into an insertion instrument which is only insubstantially larger in the insertion region than the cross-section of the elongated elastic body in order to reach the inner space of an intervertebral disc through a small opening in the annulus fibrosus and to push in and sever off the self winding spiral when the interior is filled. This has the advantage that inner spaces of differing sizes can be filled with the same spiral.
