Abstract

A method of controlling a remote navigation system that remotely orients the distal end of the medical device in order to navigate a medical device through a body lumen, the method comprising: displaying an exterior image of the body lumen; superimposing an indicator of the current position of the medical device in the body lumen; displaying a plurality of segment labels; receiving oral commands and recognizing one of the spoken displayed segment labels; and causing the remote navigation system to orient the distal end of the device in a preselected direction associated with the segment corresponding to the displayed segment label.

Claims

1. A method of controlling a remote navigation system that remotely orients the distal end of the medical device in order to navigate a medical device through a body lumen or catheter, the method comprising:

introducing a medical device within a body lumen;

displaying on a display device an image of a body lumen or cavity divided into a plurality of segments in which the centerline direction of each segment does not vary by more than a predetermined angular amount;

displaying on the display device a label for at least one of the segments;

receiving oral commands using a system adapted to receive and process oral commands, and recognizing an oral identification of a particular segment label that is being displayed on the display device as an identified segment; and

transforming the identified segment by causing the remote navigation system to orient the distal end of the medical device that is within the body lumen in a predetermined direction corresponding to the identified segment associated with the recognized segment label.

2. The method according to claim 1 further comprising superimposing an indicator of the current position of the medical device on the display device displaying the image of the body lumen or cavity.

3. The method according to claim 2 further comprising displaying on the display device an image of the portion of the body lumen through which the distal end of the medical device is being navigated, and indicating on the display device the present position of the distal end of the medical device by highlighting a ring on the surface of the displayed image of the body lumen in the plane perpendicular to the centerline of the lumen at the current position of the distal end of the catheter.

4. The method according to claim 1 wherein labels for a plurality of segments are displayed on the display device.

5. The method according to claim 1 wherein the predetermined direction associated with each segment is the average direction of the centerline of the segment.

6. The method according to claim 1 wherein the predetermined direction associated with each segment is the direction at the midpoint of centerline of the segment.

7. The method according to claim 1 wherein the predetermined direction associated with each segment is the direction at an end point of centerline of the segment.

8. The method according to claim 1 wherein the segments are automatically defined based upon a predetermined variance of centerline direction.

9. The method according to claim 1 wherein the segments are defined by the user.

10. The method according to claim 1 wherein the labels are automatically generated.

11. The method according to claim 1 wherein the labels are created by the user.

12. The method according to claim 1 wherein the image of the body lumen or cavity being displayed on the display device is generated from three-dimensional imaging data.

13. The method according to claim 1 wherein the image of the body lumen or cavity being displayed on the display device is generated from two two-dimensional images.

14. A method of controlling a remote navigation system that remotely orients the distal end of the medical device in order to navigate a medical device through a body lumen or catheter, the method comprising:

introducing a medical device within a body lumen;

processing imaging data of a body lumen or cavity to divide the lumen into a plurality of segments in which the centerline direction of each segment does not vary by more than a predetermined angular amount;

displaying on a display device an image of a body lumen or cavity divided into a plurality of segments in which the centerline direction of each segment does not vary by more than the predetermined angular amount;

displaying a label for a plurality of the segments;

receiving oral commands using a system adapted to receive and process oral commands, and recognizing in the oral commands an oral identification of a particular segment label that is being displayed on the display device as an identified segment; and

transforming the identified segment by causing the remote navigation system to orient the distal end of the medical device that is within the body lumen in a predetermined direction corresponding to the identified segment associated with the recognized segment label.

15. The method according to claim 14 further comprising superimposing an indicator of the current position of the medical device on the display device displaying the image of the body lumen or cavity.

16. The method according to claim 15 further comprising displaying on the display device an image of the portion of the body lumen through which the distal end of the medical device is being navigated, and indicating on the display device the present position of the distal end of the medical device by highlighting a ring on the surface of the displayed image of the body lumen in the plane perpendicular to the centerline of the lumen at the current position of the distal end of the catheter.

17. The method according to claim 14 wherein labels for a plurality of segments are displayed on the display device.

18. The method according to claim 14 wherein the predetermined direction associated with each segment is the average direction of the centerline of the segment.

19. The method according to claim 14 wherein the predetermined direction associated with each segment is the direction at the midpoint of centerline of the segment.

20. The method according to claim 14 wherein the predetermined direction associated with each segment is the direction at an end point of centerline of the segment.

21. The method according to claim 14 wherein the segments are automatically defined based upon a predetermined variance of centerline direction.

22. The method according to claim 14 wherein the segments are defined by the user.

23. The method according to claim 14 wherein the labels are automatically generated.

24. The method according to claim 14 wherein the labels are created by the user.

25. The method according to claim 14 wherein the direction associated with at least one section is based at least in part upon the adjacent sections.

26. A method of controlling a remote navigation system that remotely orients the distal end of the medical device in order to navigate a medical device through a body lumen or catheter, the method comprising:

introducing a medical device within a body lumen;

processing image data of a body lumen to divide the body lumen into a plurality of segments in which the centerline direction of each segment does not vary by more than a predetermined angular amount;

displaying on a display device an image of a body lumen or cavity divided into a plurality of segments in which the centerline direction of each segment does not vary by more than the predetermined angular amount;

displaying a label for a plurality of the segments;

giving oral commands including the label associated with a segment of the body lumen or catheter to an interface system capable of recognizing the label;

receiving the oral commands using a system adapted to receive and process oral commands, and recognizing in the oral commands a particular segment label that is being displayed on the display device as an identified segment; and

transforming the identified segment by operating the remote navigation system to orient the distal end of the medical device that is within the body lumen in a predetermined direction corresponding to the identified segment associated with the recognized segment label.

27. The method of claim 26, further comprising the steps of advancing the medical device under the control of the user, determining the position of a medical device in the body lumen;

and automatically orienting the distal end of the medical device in the direction of the centerline of a particular identified segment of the lumen based on a voice command from the user.
