Three years after the U.S. FDA approval of Abbott Laboratories’ Amplatzer Amulet, results of its investigational device exemption trial failed to notably differentiate Abbott’s left atrial appendage occluder system from Boston Scientific Corp.’s market-dominant Watchman device beyond the ability to forego anticoagulants quickly after implantation.
Boston Scientific Corp.’s OPTION study demonstrated left atrial appendage closure with the Watchman Flx device reduced risk of stroke compared to management with direct oral anticoagulants or warfarin in patients with atrial fibrillation following cardiac ablation. Results were presented at the American Heart Association's Scientific Sessions 2024 and simultaneously published in The New England Journal of Medicine.
Boston Scientific Corp. resumed enrollment in the AVANT GUARD trial of the Farapulse pulse field ablation (PFA) system after a pause reported in October “to assess a few unanticipated observations.” The trial aims to expand the indications for the market-leading PFA system to include a new population, drug-naïve patients with persistent atrial fibrillation.
Almost a year after U.S. FDA approval of the first pulsed field ablation device for treatment of atrial fibrillation, Johnson & Johnson secured FDA approval for its Varipulse system, intensifying competition in the rapidly growing market.
Boston Scientific Corp. signed a definitive agreement to acquire Cortex Inc., from Ajax Health Inc. to develop an integrated mapping and ablation solution for cardiac arrhythmias. Cortex’s Optimap system employs a basket catheter and algorithm to identify active sources for atrial fibrillation beyond the pulmonary veins on which most mapping and ablation technology currently focus.
The ACURATE study of the Accurate neo2 TAVR device by Boston Scientific Corp., failed to demonstrate the device is non-inferior to established devices, but the COVID-19 pandemic threw up some roadblocks.
Remote monitoring for patients with implanted cardiac electrophysiology devices may finally be coming of age in the U.K. thanks to a review of these systems by the National Institute for Health and Care Excellence.
Boston Scientific Corp. posted another eye-popping quarterly report, led by a 177% year-over-year increase in its electrophysiology business to $527 million, which exceeded consensus expectations by $99 million. That stunning EP growth follows 125% growth in the second quarter and 70% in the first quarter, all largely attributed to the Farapulse pulsed field ablation system, which achieved unprecedented adoption rates.
The U.S. FDA urged doctors and patients to use CT imaging if possible, when the MRI compatibility of any electronic implanted devices is unknown because problems with CT imaging are "extremely low" in these circumstances.
Boston Scientific Corp. racked up a two-fer from the U.S. FDA with approval of its navigation-enabled Farawave Nav ablation catheter and 510(k) clearance for the Faraview software for use with its Farapulse pulsed field ablation (PFA) system.
