S4 Medical has developed the esolution® device, the only FDA-cleared tool that provides bilateral deviation of the esophagus during catheter ablation for atrial fibrillation, reducing the risk of thermal injury. This device is compatible with any ablation energy source and significantly decreases the incidence of esophageal injury, which affects up to 47% of patients undergoing such procedures.

Problem
During catheter ablation for atrial fibrillation, the esophagus, which lies close to the point of ablation, is susceptible to thermal injury. Esophageal injury has been reported in up to 47% of patients undergoing AF ablation.
Solution
S4 Medical's esolution® device is the only FDA-cleared tool designed to deviate the esophagus bilaterally during catheter ablation for atrial fibrillation, thereby reducing the risk of thermal injury. The device uses vacuum suction to provide deviation to either the left or right, accommodating each patient’s pulmonary vein anatomy and any lesion strategy. This flexibility allows electrophysiologists to determine when and where deviation is needed, enabling ablation to be performed with confidence anywhere in the left atrium. The esolution® device is compatible with any ablation modality and does not require unique hardware, software, or other accessories.
Target Audience
The primary users are electrophysiologists performing catheter ablation for atrial fibrillation.
