Abstract: Devices, systems, and methods for performing ablation therapy on body tissue are disclosed. An example ablation device for treating body tissue includes an ionically conductive balloon and a radio-frequency electrode that delivers RF energy into a distal section of the balloon. The balloon is configured to transmit the RF energy in a direction distally towards a leading end of the ablation device. Multiple ablation electrodes on the device can be used for providing lesions of different size or shape.

Abstract: An electrophysiology system comprises an ablation catheter, a radiofrequency generator, and a mapping processor. The ablation catheter has a tissue ablation electrode and a plurality of microelectrodes distributed about the circumference of the tissue ablation electrode and electrically isolated therefrom. The plurality of microelectrodes define a plurality of bipolar microelectrode pairs. The mapping processor is configured to acquire output signals from the bipolar microelectrode pairs, compare the output signals, and generate an output to a display providing a visual indication of a characteristic of the microelectrodes and the tissue ablation electrode relative to myocardial tissue to be mapped and/or ablated.
