ABSTRACT:
Method for guiding a catheter within a lumen system of the body of a patient includes receiving consecutive position inputs from a user to guide the catheter in real time within the lumen system, determining a user defined position for the catheter tip determining continuously successive incremental paths along a trail defined by a plurality of user defined positions, and directing a moving mechanism to incrementally move the catheter within the lumen system along each of the incremental paths, each of the user defined positions being determined for each of the received consecutive position inputs, the successive incremental paths being determined between a real time catheter tip position and the adjacent proceeding user defined position, according to a topological representation of the lumen system, the moving mechanism being directed to incrementally move the catheter from each of a plurality of real time positions, toward the adjacent proceeding user defined position.
