The October 2024 launch of the Farapulse Nav system, integrating advanced mapping, further cements BSX's leadership. This innovation has driven over 140% growth in the electrophysiology segment in Q1 2025, with adoption by more than 60% of AFib ablation procedures in leading centers. Physicians favor Farapulse for its selective tissue targeting and reduced collateral damage, differentiating it from Medtronic’s PulseSelect and Johnson & Johnson’s Varipulse systems Boston Scientific's Farapulse Market Leadership.
WATCHMAN Device: Cornerstone of Structural Heart Growth#
The WATCHMAN device remains a cornerstone of BSX’s structural heart business, driving significant revenue contributions and procedural volume growth. Its role in stroke prevention for AFib patients, offering a minimally invasive alternative to anticoagulation therapy, has led to expanded clinical indications and reimbursement support.
Sales performance has consistently outpaced expectations, with over 50% of US electrophysiology centers performing concomitant WATCHMAN and PFA procedures. This synergy enhances procedural efficiency and patient outcomes, solidifying Boston Scientific’s market share in the left atrial appendage closure (LAAC) segment.
Financial Performance and Growth Metrics#
