1. Katheteranordnung aus Kunststoff, mit einem Außenkatheter (2) und einem darin angeordneten, längsverschieblichen Innenkatheter (1), der ein Arbeitslumen aufweist zur Aufnahme verschiedener Arbeitswerkzeuge, dadurch gekennzeich­ net, daß zur verbesserten Steuerbarkeit des Innenkatheters der Außenkatheter eine größere Biegesteifigkeit aufweist als der Innenkatheter und der im normalen Gebrauchszustand über das distale Ende des Außenschlauches axial vorstehende distale Endabschnitt des Innenkatheters gekrümmt vorgeformt ist mit einem sich in Längsrichtung verändernden Krümmungsradius, wobei die vorgeformte Krümmung des distalen Endabschnittes in mindestens einer Krümmungsebene vorgesehen ist und sich beim Zurückziehen des Innenkatheters in den Außenka­ theter an die jeweilige Krümmung des Außenkatheters anpaßt.1.Catheter arrangement made of plastic, with an outer catheter ( 2 ) and a longitudinally displaceable inner catheter ( 1 ) arranged therein, which has a working lumen for receiving various working tools, characterized in that the outer catheter has greater flexural rigidity than that for improved controllability of the inner catheter The inner catheter and the distal end portion of the inner catheter projecting axially beyond the distal end of the outer tube in the normal state of use is pre-shaped with a radius of curvature which changes in the longitudinal direction, the pre-shaped curvature of the distal end portion being provided in at least one plane of curvature and when the inner catheter is pulled back into the Außenenka adapts to the curvature of the outer catheter. 2. Katheteranordnung nach Anspruch 1, dadurch gekennzeichnet, daß die vorgeformte Krümmung des distalen Endabschnittes in mindestens zwei Krüm­ mungsebenen vorgesehen ist, die sich unter einem Winkel größer als Null schnei­ den.2. Catheter arrangement according to claim 1, characterized in that the preformed curvature of the distal end section in at least two bends mung planes is provided which intersect at an angle greater than zero the. 3. Katheteranordnung nach Anspruch 2, dadurch gekennzeichnet, daß zwei Krümmungsebenen vorgesehen sind, die zueinander senkrecht stehen.3. Catheter arrangement according to claim 2, characterized in that two Planes of curvature are provided which are perpendicular to each other.
