Abstract

Systems and methods are provided for remotely navigating an elongate medical device in an operating region in a subject'"'"'s body at a local procedure site, under the control of a user at a remote site. A navigation system having a controller responsive to signals from a local computer is provided. An imaging system displays an image of the operating region on a local display, and a physiology monitoring system displays information about the subject. The system utilizes a local computer for providing instructions from a local user to the navigation system controller, and a remote computer for providing instructions from a remote user to the navigation system controller. A display is provided at the remote site, and a video linking system provides a combined video display at the remote site. The system further includes an audio linking system and a data linking system for providing data communication between the remote and local sites.

an audio linking system for providing two way audio communication between the local procedure site and the remote site; and

a data linking system for providing data communication between a computer at the remote site and the navigation system controller and the advancer system controller, wherein the data linking system communicates signals input by a user of the computer at the remote site for remotely controlling operation of the navigation system at the local site.

2. The system of claim 1, wherein the navigation system is configured to give priority to control signals received from the local controller from a local user over control signals received from the remote computer via the data linking system.

3. The system of claim 1, wherein the navigation system is configured to execute the control signals received from the remote computer via the data linking system upon authorization from a local user at the local site.

4. The system according to claim 1 wherein the at least one medical imaging system is one of the group consisting of a fluoroscopic imaging system, a magnetic resonance imaging system, and an ultrasound imaging system.

5. The system according to claim 1 wherein the at least one subject physiology system is a system for measuring and displaying electrical activity.

6. The system according to claim 1 wherein the at least one subject physiology system is a system for measuring and displaying an electrocardiogram.

7. The system according to claim 1 wherein the at least one video imaging system includes one of a stationary camera for making a video image of the subject during the procedure, or a mobile camera for making a video image of the procedure site responsive to directions from a user at the remote site.

8. The system according to claim 1 wherein the navigation system is one of a magnetic navigation system that applies a magnetic field to orient a magnetically responsive element associated with the distal end of the elongate medical device, a robotic system that orients the distal end of the elongate medical device, or an electrostrictive system that orients the distal end of the elongate medical device.

9. A system for navigating a medical device in an operating region in a subject'"'"'s body at a local procedure site, under the control of a user at a remote site, the system comprising:

a navigation system at the local site for controllably navigating the medical device in the operating region within the subject, the navigation system including a controller responsive to control signals provided from a computer, for applying a magnetic field to selectively orienting the distal end of the flexible medical device in a desired direction;

a local device advancer for advancing and retracting the device in the operating region, the device advancer including a controller responsive to control signals provided from a computer;

at least one local fluoroscopy imaging system for displaying an image of the operating region on a local display;

at least one video camera imaging system for providing video images of the local procedure site on a local display;

at least one subject physiology monitoring system for displaying information about the subject'"'"'s physiology on a local display;

a local computer for providing instructions from a local user to the navigation system controller and the advancer controller;
