HELIOSTAR™ Balloon Ablation Catheter is the first-ever radiofrequency balloon ablation catheter and supports more efficient cardiac arrhythmia ablation procedures

IRVINE, CA – September 28, 2021 – Biosense Webster, Inc., part of the Johnson & Johnson Medical Devices Companies* today announced post-approval procedures were successfully performed with the first-ever radiofrequency balloon ablation catheter at sites across Europe with Biosense Webster’s HELIOSTAR™ Balloon Ablation Catheter. In Europe, the HELIOSTAR Balloon Catheter is indicated for use in catheter-based cardiac electrophysiological mapping of the atria and for cardiac ablation.

The novel HELIOSTAR™ Balloon Ablation Catheter is the first-ever radiofrequency balloon ablation catheter

Europe is home to more than 11 million people living with atrial fibrillation (AF), and estimates state that by 2030 the number of people with AF is projected to increase by up to 70%.1,2 Catheter ablation is a recommended first-line treatment option**13 and is associated with a significant improvement in quality of life and significant reductions in AF burden and AF-related complications.3,4,5

The HELIOSTAR™ Balloon Ablation Catheter, with the LASSOSTAR™ Catheter and CARTO™ 3 System, allows physicians to provide more efficient ablation procedures, with lower procedure times and reduced fluoroscopy time and exposure***, potentially benefitting both the patient and physician.6,7,8 Shorter procedure time may require less anesthesia and radiation and may result in less nursing and facility time. These time savings may also enable more procedures per day facilitating improved patient access.9,10

The novel HELIOSTAR™ Balloon Ablation Catheter features ten gold-plated, irrigated electrodes that can be tailored based on anatomical location and known tissue thickness**** enabling personalized ablation procedures for unique patient anatomies and arrhythmias.8,11,12 The amount of power delivered to each electrode can be controlled independently to provide electrophysiologists with greater customization, control and the ability to achieve pulmonary vein (PV) isolation in approximately ten seconds.*****7

“Pulmonary vein isolation is a technically complex and time-consuming procedure so it’s important that advancements in balloon ablation systems help electrophysiologists quickly and easily isolate the pulmonary veins, while maintaining safety,” said Ahmed Abdelaal, Senior R&D Director and HELIOSTAR Project Leader at Biosense Webster. “The HELIOSTAR™ Balloon Ablation Catheter was developed with electrophysiologists in mind giving them the ability to perform personalized ablation procedures with a short duration, to better meet patient’s needs.”

In a multicenter single-arm study, SHINE, the HELIOSTAR™ Balloon Ablation Catheter was an effective treatment for paroxysmal atrial fibrillation (AF) and isolated targeted pulmonary veins (PV) in 98.8% of patients without the need for focal touch-up.******7 On average, time to isolation of the pulmonary vein was approximately ten seconds, total procedure time was less than 90 minutes and dwell time was less than 40 minutes.*****,*******7

“HELIOSTAR™ Balloon Ablation Catheter reaffirms our commitment to partnering with physicians to advance the practice of electrophysiology and to help change the lives of patients suffering from atrial fibrillation,” said Uri Yaron, Worldwide President of Biosense Webster, Inc. “With CE mark approval and the first commercial procedures completed, we have made significant progress in providing electrophysiologists with another novel option for the safe and efficient treatment of this burdensome disease.”
