A guide device including a polymer and/or plastic tube, in particular a tube containing a polysiloxane, through the continuous opening of which a cable which is moveable in the continuous opening has been routed. To markedly reduce the wear caused by the cable rubbing in the continuous opening of the tube, a coating is provided on the outer surface of the cable and/or the inner surface of the continuous opening, which includes mainly particles that are substantially spherical and/or cylindrical and can move freely at least on the particular surface (e.g., outer surface of the cable and/or inner surface of the continuous opening). Furthermore, a medical device containing such a guide device, and a method for manufacturing the guide device or the medical device are described.
