Atraverse Medical, Inc. is a privately held medical device company founded in 2022 and headquartered in Encinitas, California. The company specializes in next-generation left-heart access technologies for interventional cardiac procedures, particularly transseptal access to the left atrium.
Its flagship product, the FDA-cleared HOTWIRE™ Transseptal Access System, consists of a radiofrequency (RF) guidewire and generator. Key features include impedance-sensing automatic energy shutoff to minimize RF exposure post-crossing, universal compatibility with multiple sheaths, enhanced tip visibility under intracardiac echocardiography, and a zero-exchange workflow design for procedural efficiency. The system has been utilized in nearly 3,000 clinical procedures.
In April 2026, Johnson & Johnson announced a definitive agreement to acquire Atraverse Medical to bolster its cardiac ablation portfolio for treating atrial fibrillation and other arrhythmias, with the transaction expected to close in Q2 2026 subject to customary conditions.
