Catheters and Tools with Pulsed Field Ablation-Pulmonary Vein Isolation with Focal Lattice-Tip Affera Sphere 9.

The Affera system features a versatile and large footprint catheter with a lattice-tip design that is capable of delivering both pulsed field and radiofrequency energy. It provides precise mapping and ablation capabilities, demonstrating high acute success rates and durable lesion formation, with excellent safety profile in both radiofrequency and pulsed field ablation modes. Preclinical and clinical studies have shown high lesion durability, reduced procedural time, and promising outcomes in pulmonary vein isolation with minimal complications.
