Advances in Atrial Fibrillation Ablation Devices 47 2 Figure 2. Different Balloon-based Ablation Devices for Pulmonary Vein Isolation. The second and third-generation cryoballoon (with a shorter tip indicated with arrows for better pulmonary vein recordings) (A) with a spiral catheter inside the balloon. The hotballoon (B): the inflated balloon with a thermocouple and radiofrequency electrode inside and a central lumen for a guide wire and the laserballoon (C) with an endoscope and arc generator in the catheter shaft inside the balloon. Images are respectively derived from Chierchia et al. (169), Sohara et al (109) and Reddy et al. (110)
