Occlutech® Announces FDA Approval of its Occlutech® ASD Occluder and Occlutech® Pistol Pusher, a Minimally Invasive Cardiac Device and Delivery System to Treat Atrial Septal Defects

Occlutech ASD Occluder delivers positive procedural outcomes with strong efficacy and a low rate of complications[I] 

Occlutech®, a world leading specialist provider of minimally invasive structural heart implants, today announced that the United States Food and Drug Administration (FDA) has approved the Occlutech® ASD Occluder and Occlutech® Pistol Pusher for the treatment of Atrial Septal Defects (ASD). With this approval, Occlutech will immediately begin commercialization in an exclusive partnership with distributor B. Braun Interventional Systems Inc. (B. Braun Interventional Systems).

ASDs are one of the most common congenital heart defects (CHD) seen in pediatric cardiology[ii]. An ASD is a hole in the septum, or wall, between the two upper chambers of the heart (atria)[iii]. This opening causes abnormal blood flow between the atria and may result in too much blood flow to the lungs. If left untreated, an ASD can lead to fatigue, shortness of breath, pulmonary hypertension, heart failure, arrhythmia and/or an enlarged heart.

Sabine Bois, Occlutech CEO commented, “Today marks a momentous occasion for Occlutech and a significant leap forward in our commitment to advancing healthcare around the globe. I am thrilled the FDA has granted approval for the Occlutech ASD Occluder and Occlutech Pistol Pusher. Our mission has always been to improve the quality of life for patients; indeed, we have sold over 90,000 of our ASD devices outside of the U.S. Now, with the FDA’s approval, we are poised to leverage our experience in the largest congenital and structural heart disease market in the world, with ASD closure representing a $40 million market in the US with solid growth predicted.

Bois continued, “We extend our deepest gratitude to the patients, partners and all stakeholders who have been instrumental in this journey.”

An ASD can be closed by a minimally invasive procedure. A catheter is inserted via a blood vessel in the groin and guided to the heart. The Occlutech ASD Occluder is a self-expanding Nitinol double disc occlusion device comprised of two umbrella-shaped flexible discs with a ‘waist’ in the middle that connects the two discs. Designed to be a lifelong solution, the discs attach to both sides of the atrial septum, bridging the defect and closing the hole.

Prof. Ziyad M. Hijazi, Chairman, Department of Cardiovascular Diseases and Professor of Pediatrics & Medicine, Sidra Medicine and Weill Cornell Medicine- Doha commented, “This landmark approval is a huge milestone. The Occlutech ASD Occluder has demonstrated excellent procedural outcomes and a low complication rate, per rigorous scientific study and clinical trials of >5000 studied patients in retrospective, prospective and randomized clinical trials as well as comparative meta-analysis. Therefore, to have the device available to our patients in the U.S. will only serve to help thousands more people in need.”

In an agreement signed May 2022, B. Braun Interventional Systems will immediately initiate the U.S. commercialization activities for the Occlutech ASD Occluder with the support of the global Occlutech team. Through the collaboration, Occlutech positions itself for success in the strategically important U.S. market, which is characterized as a premier and commercially attractive healthcare system, while B. Braun Interventional Systems increases its portfolio’s relevancy around its strong congenital and structural heart focus.

“We are honored to bring the trusted Occlutech ASD Occluder, with its strong body of clinical evidence into our portfolio of devices developed to treat congenital heart defects,[i,iv] said Dave Mittl, VP Sales and Marketing, B. Braun Interventional Systems. “Our legacy at B. Braun Interventional Systems has been to deliver solutions to interventionalists treating these often-overlooked patients. This portfolio addition builds on that commitment,” Mittl concluded.
