Johnson & Johnson has signed a definitive agreement to acquire Atraverse Medical; a privately held firm focused on advanced left-heart access technologies and radiofrequency (RF) solutions.
The acquisition centers on Atraverse Medical’s HOTWIRE™ Transseptal Access System, an FDA-cleared RF guidewire and generator platform designed to improve access to the left atrium during cardiac procedures. Left atrial access is a critical step in catheter-based ablation for atrial fibrillation, where precision and safety directly influence procedural outcomes.
According to the company, the HOTWIRE™ system has been used in nearly 3,000 clinical procedures. It incorporates features aimed at improving control and efficiency, including impedance-based automatic energy shutoff, compatibility with multiple sheath systems, and enhanced tip visibility under intracardiac echocardiography.
These design elements support more consistent and controlled transseptal access.
Johnson & Johnson stated that the planned acquisition would strengthen its cardiac ablation portfolio by adding differentiated tools for electrophysiologists treating atrial fibrillation and other cardiac arrhythmias. The integration of Atraverse Medical’s technology is expected to complement existing offerings in electrophysiology.
The transaction is anticipated to close in the second quarter of 2026, subject to customary closing conditions. Financial terms were not disclosed.
