DUBLIN, March 15, 2023 /PRNewswire(opens new window)/ -- Medtronic (NYSE:MDT) announced today that it has received CE (Conformité Européenne) Mark for the Affera™ Mapping and Ablation System, which includes the Sphere-9™ Catheter and the Affera™ Prism-1 Mapping Software. Together, the full system creates a new paradigm in electrophysiology through the unique integration of the Sphere-9 pulsed field ablation (PFA), radiofrequency (RF), and high density (HD) mapping catheter, which maps and ablates atrial arrhythmias (fast, abnormal heart rhythms) and provides real-time feedback through its intuitive mapping and navigation software. Atrial fibrillation (AFib) is the most common atrial arrhythmia, and nearly 60 million people are affected worldwide1 and five million patients will be added every year by 20302. Atrial arrhythmias, such as AFib, are associated with serious complications including heart failure, stroke and increased risk of death3-6.

The Sphere-9 Catheter, coupled with the integrated mapping and navigation system, quickly generates sophisticated electro-anatomical maps allowing the physician to deliver wide-area focal ablation lesions of choice between RF or PFA, based on the patient and procedure needs. Given its size, the all-in-one catheter's nitinol 9mm ablation tip has the potential to require fewer focal ablation lesion applications that may result in lower procedure times than standard irrigated ablation catheters7. The intuitive mapping software enables an optimized user experience by delivering streamlined insights and feedback to support procedure performance.

"The revolutionary Affera Mapping and Ablation System combined with the novel Sphere-9 Catheter represent a great advancement in the field of HD mapping and focal ablation," said Khaldoun Tarakji, M.D., MPH, vice president, chief medical officer, Cardiac Ablation Solutions business, which is part of the Cardiovascular Portfolio at Medtronic. "Current technologies require the use of separate HD mapping and ablation catheters. The ability to map, ablate, and validate with the Sphere-9 Catheter enables the physician to eliminate the need to exchange catheters and empowers them to choose the energy source, whether RF or PF, based on the patient's needs. All this leads to improving efficiency and most importantly, enhancing the safety of ablation procedures for our patients."
Supported by results from clinical studies assessing the safety and performance of the Sphere-9 Catheter and Mapping System, CE Mark approval comes on the heels of a December 2022 announcement that enrollment was completed in the Affera SPHERE Per-AF Clinical Trial, a randomized, controlled U.S. Food and Drug Administration (FDA) Investigational Device Exemption (IDE) pivotal trial. Designed to evaluate the safety and effectiveness of the Affera Mapping and Ablation System for the treatment of persistent atrial fibrillation, the SPHERE PER-AF IDE trial is currently in its 12 month follow up phase.
