Abstract
An electrophysiological catheter and an ablation system comprising a control device, an ablation energy output device and the electrophysiological catheter. The control device controls the ablation energy output device to selectively provide a first fluid or a second fluid that is a frozen liquid to the electrophysiological catheter. When the ablation energy output device provides the first fluid, the control device controls a first heating component on the electrophysiological catheter to work to heat the fluid entering the electrophysiological catheter for spraying a thermal ablation gas onto the inner surface of a balloon; and when the ablation energy output device provides frozen liquid, the control device controls the first heating component not to work to directly spray the frozen liquid to the inner surface of the balloon.
