The invention relates to a guide device ( 1 ), in particular for positioning catheters in a body duct. The guide device ( 1 ) has an extended first thread ( 2 ) and at least one extended second thread ( 3 ) made from wire, which runs close to the first thread ( 2 ). According to the invention, the guide device ( 1 ) has a device ( 8 ), provided for one of the threads ( 2, 3 ) by means of which it is possible to actively control a relative movement between the threads ( 2, 3 ) or at least make the same difficult. The control device ( 8 ) is for example embodied such that the first thread ( 2 ), prepared from a flexible material, exerts a pressure, preferably acting in a radial direction, on the several second threads, or that magnetic fields ( 4 ) of differing polarities along the first thread ( 2 ), prepared from a flexible material and along the second thread ( 3 ), may be generated for the selective introduction of an opposing attraction of the threads ( 2, 3 ) for reinforcing the guide device ( 1 ).
