摘要： A method of turning a medical device with the assistance of an externally applied magnetic field, in a direction with a component in a plane perpendicular to the direction of the externally applied magnetic field. The method includes applying first torque to the distal end of the medical device by creating magnetic moment at the distal end of the medical device, and applying a second torque to the distal end of the medical device. The second torque may be created by creating a second magnetic moment at the distal end of the device spaced from the first, by using an electrostrictive device, by using a stylette inserted into the device, by using a fluid-driven shaped tube, or otherwise.

摘要： A method for controlling a remote navigation system includes 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 in each location. At least once thereafter, the remote navigation system is operated 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. A local extreme value of the sensed physiological property is thereby located. The physiological properties that can be sensed include electrical signals, conductivity, temperature, fluid flow rate or fluid velocity, and range of motion of a surface.

摘要： 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.
