S4 Medical develops and offers esolution®, the only FDA-cleared device designed to deviate the esophagus and reduce the risk of thermal injury during ablation for atrial fibrillation. The esolution device provides bilateral deviation to accommodate each patient's pulmonary vein anatomy, allowing electrophysiologists to perform ablation with confidence in the left atrium. It is specifically developed for catheter ablation workflow, compatible with any ablation modality and mapping system, and does not require unique hardware or accessories. S4 Medical is dedicated to creating safer and more effective catheter ablation treatments for atrial fibrillation.
