Abstract

Claims (25)

1. A way-pointing method comprising:

receiving a three-dimensional model of a tissue region;

selecting a plurality of sites of interest on the three-dimensional model of the tissue region;

generating, via at least one computer processor, a site boundary for a first site of interest of the plurality of sites of interest and navigational information from the first site of interest to a second site of interest of the plurality of sites of interest; and

displaying the site boundary and the navigational information on an image generated by a visualization catheter to guide the visualization catheter from the first site of interest to the second site of interest, wherein the image generated by the visualization catheter and the navigational information change as the visualization catheter is moved from the first site of interest toward the second site of interest.

2. The way-pointing method of claim 1 , wherein the navigational information includes directional guidance from the first site of interest to the second site of interest.

3. The way-pointing method of claim 1 , wherein the navigational information includes distance guidance from the first site of interest or the second site of interest.

4. The way-pointing method of claim 1 , further comprising displaying identification information for the first site of interest.

5. The way-pointing method of claim 4 , wherein the identification information for the first site of interest is displayed in a listing of the plurality of sites of interest.

6. The way-pointing method of claim 1 , wherein the plurality of sites of interest are ablation sites at least partially surrounding a pulmonary vein ostium.

7. The way-pointing method of claim 1 , wherein the three-dimensional model is a pre-operative three-dimensional model.

8. The way-pointing method of claim 1 , wherein the three-dimensional model is a uniquely generated three-dimensional model.

9. A way-pointing method comprising:

receiving a three-dimensional model of a tissue region;

selecting a plurality of sites of interest on the three-dimensional model of the tissue region;

generating, via at least one computer processor, navigational information for navigating the plurality of sites of interest with a visualization catheter, wherein the navigational information includes a representation of an idealized position or orientation of the visualization catheter for creating an optimal lesion or performing an optimal ablation at one of the plurality of sites of interest; and

displaying, on the three-dimensional model, the plurality of sites of interest and the navigational information for navigating the plurality of sites of interest with the visualization catheter.

10. The way-pointing method of claim 9 , wherein the navigational information includes a representation of a current position or orientation of the visualization catheter.

11. The way-pointing method of claim 9 , wherein the idealized position or orientation is based on anatomical contours or structure in the three-dimensional model.

12. The way-pointing method of claim 9 , further comprising displaying a legend, the legend including a listing of the plurality of sites of interest.

13. The way-pointing method of claim 12 , wherein the legend associates each of the plurality of sites displayed on the three-dimensional model with each of the plurality of sites of interest in the listing.

14. The way-pointing method of claim 13 , wherein a unique pattern associates each of the plurality of sites of interest displayed on the three-dimensional model with each of the plurality of sites of interest in the listing.

15. The way-pointing method of claim 9 , wherein the plurality of sites of interest are ablation sites at least partially surrounding a pulmonary vein ostium.

16. The way-pointing method of claim 9 , wherein the three-dimensional model is a pre-operative three-dimensional model.

17. The way-pointing method of claim 9 , wherein the three-dimensional model is a uniquely generated three-dimensional model.
