Abstract
A device for the magnet-assisted catheter intervention comprises magnets for controlling a magnetic tip of a catheter. An x-ray device serves to generate three dimensional ambient images of a patient. A data processing unit calculates the probability of the magnetic tip colliding with an obstacle in the body of the patient from the ambient images and the current position of the magnetic tip and if necessary acts mechanically on the guide element so as to generate a haptically perceivable signal, with which guide element the movement of the catheter is controlled.
