US20200297415

1. An ablation system comprising: (7) (4)

a radiofrequency (RF) generator configured to generate RF energy;

an ablation catheter in communication with the RF generator and including a plurality of ablation electrodes;

a camera positioned on the ablation catheter and arranged to take an image that includes at least some of the plurality of ablation electrodes; and

one or more processors configured to recommend a subset of the plurality of ablation electrodes to be activate ablation electrodes based, at least in part, on the image.

2. The ablation system of claim 1, wherein the recommendation is based, at least in part, on comparing contrast of pixels in the image around the ablation electrodes. (1) (0)

4. The ablation system of claim 1, wherein the recommendation is also based, at least in part, on impedance measurements taken by the plurality of ablation electrodes. (1) (0)

6. The ablation system of claim 1, wherein only some of the plurality of ablation electrodes are selectable, wherein the one or more processors is configured to: (0) (1)

7. The ablation system of claim 1, wherein the recommendation is based, at least in part, on limiting estimated power received by sink electrodes below a predetermined threshold. (0)

8. The ablation system of claim 1, wherein the recommended ablation electrodes form a closed circuit. (0)

9. The ablation system of claim 1, wherein the recommendation is based, at least in part, on images of the ablation electrodes taken over multiple cardiac cycles. (0)

10. The ablation system of claim 1, wherein the ablation catheter includes an expandable member carrying the plurality of ablation electrodes, wherein the camera is positioned within the expandable member. (0)

11. A computing device for generating and using a graphical user interface (GUI), the computing device comprising: (3) (1)

one or more integrated circuits configured to: generate a graphical representation of a plurality of electrodes of an ablation catheter for displaying via the GUI, and

automatically highlight a subset of the plurality of electrodes on the GUI as active electrodes based, at least in part, on impedance values associated with each of the plurality of electrodes.

12. The computing device of claim 11, wherein automatically highlighting is further based, at least in part, on analysis of images including the electrodes of the ablation catheter. (3) (0)

16. The computing device of claim 11, wherein the one or more integrated circuits is further configured to automatically designate each of the highlighted subset of the plurality of electrodes to be either a source electrode or a sink electrode. (1) (0)

20. The computing device of claim 11, wherein the automatically highlighting is further based, at least in part, determining which of the electrodes of the ablation catheter are selectable. (0)
