Order Information
PFA Catheter Pulsed Field Ablation (PFA) uses high-voltage, microsecond-duration pulsed electric fields to selectively ablate cardiomyocytes, achieving pulmonary vein isolation while avoiding thermal damage to surrounding tissues, such as the esophagus and phrenic nerve. | Active Devices Active medical devices refer to medical devices that rely on electrical energy or other energy sources (such as chemical energy, mechanical energy) to function, rather than directly utilizing energy generated by the human body or gravity. | IVUS Catheter IVUS catheter is an interventional diagnostic device that integrates a miniaturized high-frequency ultrasound transducer at the tip of the catheter. By emitting and receiving ultrasound waves within the blood vessel lumen, it generates real-time cross-sectional images of the vessel. |
