A method is provided to facilitate the movement of a medical device for
automated mapping of anatomical surfaces of a subject's heart with a
remote navigation. The method may include one or more distinct movements
for moving a medical device for mapping a portion of an anatomical
surface of a subject's heart. Upon establishing contact of the tip of the
medical device with a surface of the heart, one method provides for
moving the medical device along the surface of the heart towards an
anatomical feature until a loss of contact with the surface is sensed,
and determining the point where the loss of contact occurred to identify
at least one point along the anatomical feature. The process may be
repeated to identify a multiplicity of points that serve to define the
ridge on the interior heart surface. The ridge location in the anatomical
map can be used as a reference or guide to facilitate the further mapping
of physiological properties and to plan therapy delivery during the
medical procedure.
