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; 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. |
