Abstract

A method for controlling a remote navigation system to navigate a medical device in an operating region in a subject is provided, comprising operating the remote navigation system to bring a sensor carried on a medical device successively into a plurality of locations in a predetermined pattern, and using the sensor to sense a physiological property of the subject in each location. At least once thereafter, the method operates the remote navigation system to bring a sensor carried on a medical device successively into a series of locations in a predetermined pattern relative to at least one location selected from the predetermined pattern in the immediately preceding step based upon the sensed physiological property value, and uses the sensor to sense the physiological property in each location. The method automatically determines the location of a local extreme value of the sensed physiological property, and may be selectively used to locate a maximum value of the sensed physiological property or a minimum of the sensed physiological property. The method may be utilized for sensing one or more physiological properties such as a magnitude of an electrical signal, a conductivity, a temperature, a fluid flow rate or a fluid velocity, or a range of motion of a surface.
