Abstract
A steering system () comprises two radially oppositely arranged drive wheels () for steering a tubular object () positioned between the drive wheels (). The drive wheels () each have a wheel rotation axis () and each include a plurality of rollers () distributed around the wheel rotation axis (). The rollers () are rotatably arranged, each roller having a roller rotation axis () and an outer drive face () concavely vaulted in a direction corresponding to its roller rotation axis (). The roller rotation axis () is obliquely oriented in relation to the wheel rotation axis () and the rollers () of each drive wheel () form together a steering periphery for the tubular object (). The steering system enables continues rotation of a tubular object without danger that the object will lose the contact with the rollers. The steering system () may be incorporated in a catheter system which comprises a catheter ().
