This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
The Conquer-AF trial is testing the Sphere-9 Catheter and Affera Ablation System in patients whose atrial fibrillation has come back after one previous ablation procedure. This is a second ablation procedure designed to help control the irregular heart rhythm. The study will follow 400 patients across multiple sites in the United States, Europe, and Australia.
Some patients find that their atrial fibrillation returns even after undergoing ablation treatment. This trial exists to evaluate whether the Sphere-9 Catheter and Affera Ablation System can safely and effectively treat those recurring cases and help keep the heart rhythm stable longer.

You will come to the hospital for a second ablation procedure using the new Sphere-9 Catheter system. After the procedure and hospital discharge, you will have follow-up visits at 7 days, 3 months, 6 months, and 12 months to check how well the treatment is working. The entire study lasts about 2 years, with most of your active involvement being the initial procedure and routine follow-up appointments.
