S4 Medical Completes Development Study

Recently renamed medical device company S4 Medical Corp. successfully completed its milestone development study, which demonstrated capability of protecting the esophagus from thermal damage during catheter ablation. Catheter ablation is an effective treatment for patients with atrial fibrillation (AF), but carries risk of esophageal injury due to anatomical position of the heart and esophagus. 
 
“This is an exciting breakthrough for electrophysiologists and their patients with atrial fibrillation,” said Dr. Emile Daoud, S4 inventor and co-founder. “As ablation technologies continually improve, we need better solutions for managing esophageal damage. Current solutions fall far short.”
 
AF is an irregular heartbeat that affects nearly 30 million people worldwide. It is a serious heart condition and the leading cause of stroke. Treatment includes catheter ablation, which can completely eliminate AF, but is not without risks. One such risk is damage to the esophagus, which, while rare, can become a life-threatening complication. 
 
To address this risk, Daoud, of The Ohio State University Wexner Medical Center, and a team of physicians developed a device to better protect the esophagus during catheter ablation. “Esophageal damage is top of mind during ablation procedures.” said Daoud. “This solution will provide greater confidence, improved procedure efficiency, and ultimately better outcomes for the patient.”
 
“We are thrilled with the results we saw,” added William Fuller, S4’s CEO and co-founder. “Meeting this milestone was a major step forward and confirms the value S4’s technology can bring to the market.”

The company completed its seed round of funding in 2018, and the success of this most recent study puts the company on track for the next phases of development and funding. “Things are falling into place exactly as we’d hoped,” said Fuller. 
 
S4 Medical Corp. is a medical device company focused on solutions for cardiac procedures. The company’s initial product is a simple, yet comprehensive solution for reducing complications to the esophagus during catheter ablation treatment for atrial fibrillation.
