1. A method for guiding a catheter through a region of a patient with a catheter navigation system, the method comprising:
- tracking a location of a tracking device of the catheter while the catheter is within the region of the patient, wherein the catheter further includes at least one sensor;
measuring a physiology at discrete tracked locations within the region of the patient with the at least one sensor as the catheter is moved within the region of the patient, wherein the tracked locations are based on tracking the location of the tracking device;
executing instructions with the catheter navigation system to determine at least one location of a reference point within the region of the patient based on the measured physiology at the discrete tracked locations;
executing instructions with the catheter navigation system to generate a matched model by stretching, rotating, and aligning at least one model reference point in a model to the determined at least one location of the reference point in the region of the patient;
displaying the matched model; and
displaying a distribution map on the matched model regarding delivering at least one of a pharmaceutical agent, a volume of cells, or a genetic therapy to illustrate how the at least one of the pharmaceutical agent, the volume of cells, or the genetic therapy is disbursed through the region of the patient.

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.

6. A method for guiding a catheter through a region of a patient with a catheter navigation system, the method comprising:
-
generating a model of the region of the patient; tracking a tracking device of the catheter while the catheter is within the region of the patient, wherein the catheter further includes a sensor; measuring a physiology with at least one sensor of the region of the patient as the catheter is moved within the region of the patient; determining locations of reference points within the region of the patient based on the measured physiology and the tracked tracking device of the catheter; executing instructions with the catheter navigation system to generate a matched model by matching the model to the region of the patient by stretching, rotating, and aligning the model at the determined reference points to match the model to the determined reference points; displaying the matched model; executing instructions with the system to determine a suggested site for delivery of at least one of a pharmaceutical agent, a volume of cells, or a genetic therapy; and displaying an indication of the suggested site. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)

15. A catheter navigation system method for guiding a catheter through a region of a patient, comprising:
-
a catheter configured to be moved into the region of the patient, the catheter including, a plurality of discrete tracking devices, wherein each of the plurality of discrete tracking devices is connected to the catheter and is operable to track a plurality of positions relating to each of the respective plurality of discrete tracking devices, and a physiology sensor to measure at least a portion of a physiology at the tracked position in the region of the patient; a display operable to display an image representative of the region of the patient; and a controller in communication with the plurality of discrete tracking devices and the physiology sensor; wherein the controller is operable to execute instructions to automatically determine at least one reference point in the region of the patient based on the measured portion of the physiology and a tracked location of the catheter by tracking at least one of the plurality of discrete tracking devices; wherein the controller is operable to match a model of the region of the patient to the determined at least one reference point; wherein the controller is operable to execute instructions to determine a distribution map regarding delivering at least one of a pharmaceutical agent, a volume of cells, or a genetic therapy to illustrate how the at least one of the pharmaceutical agent, the volume of cells, or the genetic therapy is disbursed through the region of the patient; wherein the display is operable to display the distribution map. - View Dependent Claims (16, 17, 18, 19, 20, 21)
