Abstract

An image guided catheter navigation system for navigating a region of a patient includes an imaging device, a tracking device, a controller, and a display. The imaging device generates images of the region of the patient. The tracking device tracks the location of the catheter in the region of the patient. The controller superimposes an icon representing the catheter onto the images generated from the imaging device based upon the location of the catheter. The display displays the image of the region with the catheter superimposed onto the image at the current location of the catheter.

Claims

1. An image guided catheter navigation system for guiding a catheter through a region of a patient, said navigation system comprising:

an imaging device operable to generate image data of the region of the patient;

a tracking device operable to track the position of the catheter in the region of the patient;

a controller in communication with said imaging device and said tracking device and operable to superimpose an icon representing the catheter onto the image data of the region of the patient based upon the position tracked by said tracking device; and

a display operable to display the image data of the region of the patient with the superimposed icon of the catheter, wherein said catheter provides a function to the region of the patient.
