Abstract

An arrangement, for surgical or medicinal use, involving a spiral spring (l) together with a device through which this can be made to expand from a first position (fig.3; 5) with a certain diameter, to a second position (fig.2; 4) with a larger diameter and vice versa; whereby the device (4l, 42b, 43) is designed , whilst keeping the same length (L) on the spring (1; 36) , to turn the spring's ends (38, 39) relative to each other so that the transition from said first position to said second position takes place through a reduction in the number of turns in the spring within said length (L) and a corresponding increase in the spring's ascent (s) or, in order to supply further spring material (B) for a given length (L4) of the spring (1), on at least one end of the spring's (1) said length (L4) so that the transition from said first position to said second position takes place independently of the extension and the number of turns of the spring within said length (L4).<IMAGE>
