Patent Images
1. An ablation system, comprising:
- an ablation catheter having at least two flexible ablation elements;
at least one electrode affixed to each ablation element reading at least one of ECG and EKG information, and transmitting energy to tissue in a monopolar mode, a bipolar mode, and a combination monopolar-bipolar mode;
an interface unit coupled with the ablation catheter including a control interface and a visual display;
the visual display having a graphic representation of the ablation elements, the electrodes, an electrical signal from each electrode, an indication of whether each electrode is selected to transmit energy, a current quantitative representation of a system parameter, a system parameter target value, and an indication of the selected energy mode.

Abstract
Devices, systems and methods are disclosed for the ablation of tissue. Embodiments include an ablation catheter that has an array of ablation elements attached to a deployable carrier assembly. The carrier assembly can be constrained within the lumen of a catheter, and deployed to take on an expanded condition. The carrier assembly includes multiple electrodes that are configured to ablate tissue at low power. Systems include an interface unit with a visual display that provides a visual representation of the geometry of the ablation elements and/or provides selection means for selecting an icon provided on the display.
