Johnson & Johnson MedTech acquires Laminar, focused on reducing risk of stroke in AFib patients 

Johnson & Johnson MedTech on Thursday said it completed the acquisition of Laminar Inc., a privately held medical device company focused on eliminating the left atrial appendage in patients with non-valvular atrial fibrillation. Laminar joins Johnson & Johnson MedTech as part of Biosense Webster Inc. — a global leader in cardiac arrhythmia treatment.

“For the millions of people living with AFib, stroke risk is a major concern. The team at Laminar is driven by our vision to develop and deliver an innovative solution to help patients live without the fear of stroke, or the need for long-term use of blood thinners,” Randy Lashinski, CEO & president, Laminar, said. “We are looking forward to advancing this vision as part of Johnson & Johnson MedTech.”

“We are excited to welcome Laminar to Johnson & Johnson MedTech,” Jasmina Brooks, president, Biosense Webster, said. “Laminar’s innovative approach will provide Biosense Webster the opportunity to expand our portfolio in this high growth market, complement our electrophysiology and intracardiac echo strengths, and deepen our presence with interventional cardiologists and electrophysiologists. Fueled by the global scale and commercial and clinical strength of Biosense Webster, we are excited to explore the possibilities ahead to reach even more patients with critical unmet need.”

As a result of the acquisition of Laminar Inc., Johnson & Johnson will be adjusting its expected adjusted EPS for fiscal year 2023. The asset acquisition will require an in-process research & development charge, which will reduce operational and reported adjusted EPS by approximately $0.17 from guidance previously issued.

Johnson & Johnson MedTech acquired Laminar for an upfront payment of $400 million, subject to customary adjustments, with additional potential clinical and regulatory milestone payments in 2024 and beyond.

Approximately 38 million patients around the world are living with AFib, which causes them to be more than five times as likely to have a stroke. The LAA is a small pouch in the left atrium of the heart and can be a source of clots that can enter the blood stream, potentially causing a stroke. The LAA is a major contributor to thromboembolic stroke in patients with non-valvular atrial fibrillation.

Unlike current commercial catheter-based procedure devices that use plugs to occlude the LAA, Laminar’s novel approach uses rotational motion to eliminate the LAA. Laminar recently received FDA approval for the U.S. pivotal study, which will begin enrollment in early 2024.
