System and method for moving a medical device for treating or diagnosing a patient

A system for moving, in a vascular network, a medical device including a magnetic part in a head section and a controlling line in a back section, the system comprising:

• a magnetic actuator;
• a controlling unit;
• a controlling line driver;
• wherein the controlling line driver is adapted to hold and/or to release at different speeds the controlling line when the controlling line is attached to the controlling line driver,
• wherein the magnetic actuator is adapted to generate a magnetic field at a location in order to pull the medical device,
• wherein the controlling unit is adapted to balance at least three forces applied on the medical device, the at least three forces comprising a flow drag force and a force acting on the medical device through the controlling line,
• wherein the controlling unit is adapted to operate at least one of the magnetic actuator and/or the controlling line driver, and
• wherein the controlling unit is adapted to compute the at least three forces based on trajectory data that are representative for a predetermined vascular path.
