Patent ID: 10507056

Abstract:
In the present invention, a system and method for determining the orthogonality and applied force vector of an ablation catheter includes the steps of providing an electrophysiology system including an RF generator, a processor operably connected to the RF generator, a display operably connected to the processor and an ablation catheter operably connected to the RF generator and the processor, the catheter including an ablation electrode disposed opposite the RF generator and a number of microelectrodes disposed on and electrically isolated from the ablation electrode, the processor configured to compare data signals obtained from the microelectrodes with one another to derive a difference value for each pair of data signals, obtaining data signals from the microelectrodes, comparing the data signals from microelectrode pairs to determine difference values and generating a visual representation on the display of the orthogonality and applied force vector of the ablation electrode using the difference values.
