摘要： An apparatus and method for interventional navigation within a subject's body is provided in which a medica! device having at least one electrostrictive element is adapted to cause the distal end of the medical device to bend in a given direction for improving navigation. The medical device may further comprise at least one magnetically responsive element on the distal end, which may be oriented in the approximate direction of a magnetic field that is applied to the subject's body. At least one method for navigating a medical device though a subject's body is provided, by changing the direction of an applied magnetic field to align a magneticaliy responsive element on the distal end for orienting the distal end, and by applying a voltage to at least one electrostrictive element disposed in the distal portion of the device for causing the distal end to change orientation from that achieved by application of the magnetic field alone.

摘要： A control and control method for a remote navigation system including an orientation controller that orients the distal end of a medical device in an operating region in a subject, and a length controller that extends and retracts the distal end of the medical device, to navigate the distal end of the medical device to a selected destination in response to user inputs. In accordance with the control method, the control interrupts operation of at least one of the orientation controller and the length controller when the user inputs would cause the orientation controller and the length controller to navigate the distal end of the medical device to one of a plurality of predetermined restricted locations (or alternatively when the user inputs would cause the orientation controller and length controller to navigate the distal end of the medical device other than to one of a plurality of predetermined target locations). In accordance with one preferred embodiment of the method, the control can determine inputs to cause the navigation system to navigate the medical device to an unrestricted location that is closest the user's original selection (or to a target location that is closes to the user's original selection).

摘要： A system and method are provided for control of a navigation system for deploying a medical device within a subject, and for enhancement of a display image of anatomical features for viewing the projected location and movement of medical devices, and projected locations of a variety of anatomical features and other spatial markers in the operating region. The display of the X-ray imaging system information is augmented in a manner such that a physician can more easily become oriented in three dimensions with the use of a single-plane X-ray display. The projection of points and geometrical shapes within the subject body onto a known imaging plane can be obtained using associated imaging parameters and projective geometry.

摘要： The guide wire invention relates to improvements in magnetically navigable medical guide wires for enabling, in addition to magnetic navigation, conventional navigation without the use of a magnetic field. The distal portion of the guide wire may be navigated by either manually applying an axial rotation to the guide wire or by applying a magnetic field to modify the curvature of the distal portion to access small branch vessels in a subject body. The distal portion of the guide wire can also be straightened or aligned with the longitudinal axis of the guide wire by applying a magnetic field that straightens the bent section in the direction of the longitudinal axis, which enables the guide wire to push through a lesion.

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.
