Patent ID: 8345067

Claim:
A method of illustrating a selected path on a display, comprising: positioning a mapping instrument in a volume of a patient; moving a first position element in the volume with the mapping instrument; determining a plurality of positions of the first position element in the volume; generating a plurality of map data points of the volume based on the determined plurality of positions of the first position element; determining with a processor an implantation position based on one of the determined plurality of positions of the first position element within the volume of the patient; displaying a map including the plurality of map data points on a display device to illustrate an interior surface of the volume; withdrawing the mapping instrument from the volume along a selected pathway from the determined implantation position; determining a plurality of pathway positions of the first position element along the pathway as the mapping instrument is being withdrawn; illustrating the plurality of determined pathway positions superimposed on the displayed map as a pathway icon; illustrating the determined implantation position superimposed on the displayed map and the pathway icon as a landmark icon; tracking a second position element on a second instrument; and displaying a second instrument icon representing a location of the second instrument relative to the pathway icon and the landmark icon on the displayed map.
