Graphical user interfaces for ablation systems

A computing device for generating a graphical user interface (GUI), the computing device comprising:

• one or more controllers configured to:
• communicate with an ablative energy generator configured to generate ablative energy for delivery to an ablation catheter, the ablation catheter comprising a plurality of electrodes;
• display via the GUI electrode icons corresponding to the plurality of electrodes of the ablation catheter;
• receive first electrical impedance measurements from each of the plurality of electrodes at a first time;
• receive second electrical impedance measurements from each of the plurality of electrodes at a second time, wherein the second electrical impedance measurements differ from the first electrical impedance measurements;
• display an impedance indicator in association with each electrode icon, wherein the displayed positions of the impedance indicators relative to the electrode icons change based on the differences between respective first electrical impedance measurements and respective second electrical impedance measurements;
• and
• cause the ablation energy generator to transmit ablative energy to the plurality of electrodes of the ablation catheter.

A method for generating a graphical user interface (GUI), the method comprising:

• providing a computing device comprising one or more controllers configured to communicate with an ablative energy generator configured to generate ablative energy for delivery to an ablation catheter, the ablation catheter comprising a plurality of electrodes configured to sense electrical impedance;
• generating, via the one or more controllers, a graphical representation including electrode icons corresponding to the plurality of electrodes of the ablation catheter for displaying via the GUI;
• receiving, at the one or more controllers, electrical impedance sensed by each of the plurality of electrodes at a first time;
• receiving, at the one or more controllers, electrical impedance sensed by each of the plurality of electrodes at a second time;
• determining, via the one or more controllers, a change in impedance at each of the plurality of electrodes between the first time and the second time;
• generating, via the one or more controllers, an impedance indicator to be displayed via the GUI in association with each electrode icon, wherein the position of impedance indicator relative to its associated electrode icon changes based on the determined change in impedance at the corresponding electrode of the plurality of electrodes;
• causing, via the one or more controllers, the ablation energy generator to transmit ablative energy to the plurality of electrodes of the ablation catheter.
