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.

Claims16

Dependent claims

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.
