Navigation system for cardiac therapies
First Claim
1. An image guided navigation system for guiding an instrument through a region of a patient, said image guided navigation system comprising:
- an anatomical gating device operable to sense a physiological event;
an imaging device operable to capture image data of the region of the patient in response to said physiological event;
a tracking device operable to track the position of the instrument in the region of the patient;
a controller in communication with said anatomical gating device, said imaging device and said tracking device and operable to register said image data with the region of the patient in response to said physiological event, said controller further operable to superimpose an icon representing the instrument 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 instrument.

Abstract
An image guided 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 a patient. The tracking device tracks the location of the instrument in a region of the patient. The controller superimposes an icon representative of the instrument onto the images generated from the imaging device based upon the location of the instrument. The display displays the image with the superimposed instrument. The images and a registration process may be synchronized to a physiological event. The controller may also provide and automatically identify an optimized site to navigate the instrument to.
