User interface for remote control of medical devices
First Claim
Patent Images
1. An interface for controlling a magnetic navigation system that applies a magnetic field in a selected direction to an operating region in a subject to magnetically orient a medical device in the operating region, the interface comprising:
- a display on which at least one image of the operating region is displayed;
an input device for identifying a point in the operating region on the at least one image on the display;
a processor for determining an application point in the operating region on a predetermined branched path through the subject'"'"'s vasculature that is closest to the identified point, and causing the magnetic navigation system to apply a magnetic field at the application point, in a direction tangent to the predetermined path at the application point.

Abstract
An interface for remotely controlling a medical device in a patient'"'"'s body provides a two dimensional display of a three dimensional rendering of the operating region, and allows the user to select the orientation or location of the distal end of the medical device on the display and then operate a navigation system to cause the distal end of the medical device to approximately assume the selected orientation or location.

12. A method of operating a magnetic navigation system to apply a magnetic field in a selected direction in an operating region in a subject, to magnetically orient a medical device in the operating region, the method comprising:
-
identifying a plurality of points along the subject'"'"'s vasculature in an image of the operating region in the subject;
connecting each point to the closest adjacent point to create a network of navigable paths through the subject'"'"'s vasculature;
identifying a selected point on an image of the operating region, and identifying an application point that is on the network of navigable paths, closest to the selected point; and
applying a magnetic field at the application point in a direction tangent to the navigable path at the application point. - View Dependent Claims (13, 14)
