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.

The method of claim 1, wherein the determined at least one reference point includes a plurality of determined reference points. 3. The method of claim 2, wherein the plurality of determined reference points include transition points in a heart of the patient including a transition from the superior vena cava to the right atrium, passing the tricuspid valve into the right ventricle, and a left ventricular apex. 4. The method of claim 1, further comprising: displaying a catheter icon representing a location of the catheter superimposed on the matched model. 5. The method of claim 4, further comprising: executing instructions with the catheter navigation system to provide a road map information to direct the catheter through the region of the patient to a suggested target site for a treatment to be delivered by 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; anddisplaying an indication of the suggested site. 7. The method of claim 6, further comprising: registering the region of the patient with the matched model; andsuperimposing a catheter icon representing a position of at least a portion of the catheter on the displayed and registered matched model. 8. The method of claim 7, further comprising: passing a medical instrument through an open lumen defined by the catheter to the region of the patient. 9. The method of claim 7, further comprising: delivering at least one of the pharmaceutical agent, the volume of cells, or the genetic therapy through an open lumen defined by the catheter into a portion of the region of the patient. 10. The method of claim 9, further comprising: measuring a rhythm of the heart of the patient with an electrocardiogram device operable to determine an activation state or relaxation state of the heart of the patient to enable gated delivery of at least one of the pharmaceutical agent, the volume of cells, or the genetic therapy delivery, at an optimum time of the heart rhythm. 11. The method of claim 9, further comprising: displaying a distribution map regarding delivering at least one of the pharmaceutical agent, the volume of cells, or the 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 heart. 12. The method of claim 6, wherein the measured physiology includes at least one of an electrical signal morphology change and a pressure signal change. 13.
