Late-Breaking Data Shows Abbott's Amplatzer Amulet Occluder Offers Superior Left Atrial Appendage Closure Compared to Watchman? Device for People With Atrial Fibrillation at Risk of Stroke

Abbott (NYSE: ABT) today announced late-breaking data from the Amulet™ LAA Occluder IDE trial, a multi-center, head-to-head study comparing the company's Amplatzer™ Amulet Left Atrial Appendage (LAA) Occluder with the Watchman‡ device (Boston Scientific) to treat patients with atrial fibrillation (AFib) at an increased risk of stroke. The results of the trial show Abbott's Amulet device was superior for the primary endpoint of LAA closure and noninferior for the primary endpoints of safety and effectiveness versus the comparator device.

The findings were presented today in a late-breaking Hot Line session at ESC Congress 2021 organized by the European Society of Cardiology and simultaneously published in Circulation . The trial results supported the recent U.S. approval of Amulet .

The LAA is a small pouch connected to the upper left chamber of the heart. For people with AFib, the heart's ability to effectively pump blood can be disrupted, allowing blood to pool and collect in the LAA causing an increased risk for clotting. If clots reach the blood stream, they can travel to the brain and cause a stroke. Abbott's Amulet device with Dual-Seal technology (a lobe to fill the body of the LAA and a disc to close off the opening into the LAA) offers immediate closure of the LAA, reducing the risk of stroke and – unlike the study comparator device – immediately eliminates the need for blood-thinning medication following implant. Amulet Occluder also offers a wider range of sizes to help physicians treat a broad range of patients and allows recapturing and repositioning to ensure optimal placement.

"Atrial fibrillation cases have increased in recent years as the world continues to age, making stroke risk more prevalent and resulting in higher usage of blood-thinning medication that can lead to bleeding and other complications," said Dhanunjaya Lakkireddy , M.D., Kansas City Heart Rhythm Institute at HCA Midwest Health, who served as principal investigator for the study. "Amulet demonstrated a clear benefit for people suffering from atrial fibrillation who are at risk of stroke and in need of LAA occlusion. The Amulet IDE trial data show that we can effectively treat these patients with Amulet and get them off blood thinners immediately following implantation."

A Strong Foundation of Clinical Evidence
The Amulet IDE trial is the first multicenter, large-scale randomized study to compare Abbott's Amulet device head-to-head with the Watchman device.

Results from the study demonstrated that Abbott's Amulet Occluder with Dual-Seal technology:

  • Was successfully implanted in 98.4% of patients compared to 96.4% of patients receiving the Watchman device.
  • Demonstrated superiority for the primary endpoint of LAA closure compared to Watchman (98.9% vs. 96.8%, p (superiority) = 0.0025).
  • Was noninferior to the comparator device for the co-primary safety endpoint (a composite of procedure-related complications, all-cause death or major bleeding through 12 months) and co-primary effectiveness endpoint (a composite of ischaemic stroke or systemic embolism through 18 months).

Importantly for patients and their physicians, Amulet did not require the use of blood thinners for participants following implant in the study. Watchman patients were mostly (82%) discharged on anticoagulant therapy (warfarin plus aspirin). In contrast, only 20% of Amulet patients were discharged on anticoagulants, and most (75.7%) were discharged on dual antiplatelet therapy (clopidogrel plus aspirin).

"Now backed by the strength of the Amulet IDE data and the ability to immediately close the LAA, our Amulet device has the potential to change the way physicians approach LAA occlusion therapy," said Michael Dale , senior vice president of Abbott's structural heart business. "Offering immediate, superior LAA closure allows Americans living with atrial fibrillation to experience greater peace of mind against the worry of having a stroke without the need for blood-thinning medication immediately following the procedure."

The Amplatzer Amulet LAA Occluder has been approved for use in more than 80 countries, including in Europe , Canada and Australia , since its initial CE Mark approval in 2013. Amulet is part of the Abbott Amplatzer family of products with proven clinical success for more than two decades.

Medtronic Affera pulsed field ablation technologies continue to demonstrate promising evidence for atrial fibrillation patients

Medtronic Affera pulsed field ablation technologies continue to demonstrate promising evidence for atrial fibrillation patients

  • One-year clinical trial data for the next-generation, investigational, Sphere-360™ single-shot PFA catheter show impressive safety, performance, and efficiency results for paroxysmal Afib
  • Dual-energy (RF/PF), focal Sphere-9™ catheter demonstrates efficacy for linear ablation in persistent AFib
  • Medtronic continues legacy of leadership in innovation, showcasing arrhythmia management portfolio at Heart Rhythm Society annual meeting

Medtronic plc (NYSE: MDT), a global leader in healthcare technology, today announced positive clinical outcomes from two studies in atrial fibrillation (AFib) patients treated with the Affera™ family of technologies, including the next-generation Sphere-360™ single-shot pulsed field ablation (PFA) catheter and the groundbreaking Sphere-9™ combination mapping and dual-energy focal PFA catheter. Data were presented in High Impact Science Sessions at the Heart Rhythm Society 2025 Annual Meeting in San Diego ; the Sphere-360 study was simultaneously published in the Heart Rhythm Journal .

Sphere-360 Study Safety and Performance

Sphere-360 is an investigational, first-of-its-kind, single-shot PFA mapping and ablation catheter for treatment of paroxysmal atrial fibrillation (PAF). Results for Sphere-360 at one year, in a prospective, single-arm, multi-center trial performed in European centers, demonstrated freedom from arrhythmia recurrence in 88% of patients, with chronically durable pulmonary vein isolation (PVI) in 98% of targeted veins and no reported safety events in a sub-group treated with the most optimized waveform. The Sphere-360 catheter has a large, conformable lattice design that can be modified into various shapes, is seamlessly integrated with the Affera Mapping and Ablation System and utilizes an 8.5 Fr sheath – the smallest in any single-shot PFA technology.

"The Affera technology is a sophisticated ecosystem, including an advanced, intuitive mapping system and catheters that are seamlessly integrated to offer treatment options for different cardiac arrhythmias. It is encouraging to see the promising results for Sphere-360, which can easily create circumferential lesions without the need for catheter rotation," said Vivek Reddy , M.D., Director of Cardiac Arrhythmia Services for the Mount Sinai Health System in New York City . "The study results showed Sphere-360 has a promising safety and performance profile with zero serious adverse events observed. Upon approval, Sphere-360 will be a valuable addition to Medtronic's Affera system, which has been a game changer for Afib treatment and physician workflow."

Medtronic intends to begin its U.S. pivotal trial for the Sphere-360 catheter later this calendar year. Worldwide, Sphere-360 is currently investigational and not approved for sale or distribution.

Sphere-9 for Linear Ablation

Additionally, in a sub-analysis from the Sphere Per-AF IDE study , results demonstrated that the Sphere-9 catheter can be used safely and effectively to create linear lesions in persistent AF patients. Linear ablation is often used in conjunction with PVI to improve the chances of restoring a normal heart rhythm without recurrence in persistent AF patients. The Sphere Per-AF IDE study evaluated the safety, efficacy and efficiency of Affera and Sphere-9 in persistent AF and led to the FDA approval of Affera in October 2024 .

"True to our Medtronic mission for patients and legacy of innovation, we are delivering our best-in-class technologies to physicians and improving care for AFib patients, and we are not slowing down," said Rebecca Seidel , president of the Cardiac Ablation Solutions business at Medtronic, which is part of the Cardiovascular portfolio. "These results signify another step forward and energize us as we continue to earn and build our leadership position in electrophysiology every day."

Medtronic is the only company with two PFA offerings for physicians and patients. The PulseSelect™ Pulsed Field Ablation System offers physicians a safe, single-shot solution for pulmonary vein isolation (PVI) and is now available in more than 30 countries. The Affera system together with the Sphere-9 catheter enables physician treatment flexibility with its wide area focal design and 9mm lattice tip that can used with an 8.5Fr sheath. Affera is available in Europe , Australia and New Zealand , with global expansion ongoing.

AFib is one of the most common and undertreated heart rhythm disorders, affecting more than 60 million people worldwide. 1 Afib is a progressive disease, often beginning as paroxysmal AFib (presents intermittently) and progressing to persistent (lasts for more than 7+ days without stopping). As the disease progresses, the risk of serious complications including heart failure, stroke and risk of death increases 2-5 .
