Method for delivering a medical device coupled with a catheter, to a selected position within a lumen of the body of a patient, the method comprising the procedures of: registering a three-dimensional coordinate system with a two-dimensional coordinate system, the three-dimensional coordinate system being associated with a medical positioning system (MPS), the two-dimensional coordinate system being associated with a two-dimensional image of the lumen, the two-dimensional image being further associated with an organ timing signal of an organ of the patient; acquiring MPS data respective of a plurality of points within the lumen, each of the points being associated with the three-dimensional coordinate system, each of the points being further associated with a respective activity state of the organ; determining a temporal three-dimensional trajectory representation for each the respective activity states from the acquired MPS data which is associated with the respective activity state; superimposing the temporal three-dimensional trajectory representations on the two-dimensional image, according to the respective activity state; receiving position data respective of the selected position, by selecting at least one of the points along the oral three-dimensional trajectory representation; determining the coordinates of the selected position in the three-dimensional coordinate system, from the selected at least one point; determining the current position of the medical device in the three-dimensional coordinate system, according to an output of an MPS sensor attached to the catheter in the vicinity of the medical device; maneuvering the medical device through the lumen, toward the selected position, according to the current position relative to the selected position; and producing a notification output when the current position substantially matches the selected position.
