SAN DIEGO, May 15, 2024 /PRNewswire/ — Atraverse Medical, a San Diego-based medical device company, today announces the FDA clearance of its HOTWIRE™ radiofrequency (RF) guidewire, a novel device that enables zero exchange left-heart access while also acting as a rail for catheter-based therapy systems.

Dr. Mickelsen, also a cardiac electrophysiology physician at Scripps Hospital in La Jolla, CA, commented, The FDA clearance of the HOTWIRE underscores our dedication to medical innovation and our commitment to improving the standard of care for procedures requiring transseptal access including endocardial ablation, left atrial appendage closure, and mitral valve repair.” 

Dr. Devi Nair, Director of Cardiac Electrophysiology and Research at St. Bernard’s Medical Center, along with other key opinion-leading physicians will present their initial experience using the HOTWIRE during the Heart Rhythm Society (HRS) meeting in Boston, MA on May 18, 2024. “I am excited about the HOTWIRE’s ability to drive impactful change in the field of left-heart therapies, allowing physicians to use their preferred transseptal access workflow with the potential for safer, faster procedures,” stated Dr. Nair. Following the recent FDA clearance, Atraverse will conduct demonstrations of the HOTWIRE at the company’s tech suite in the HRS exhibit hall. Prior to HRS, Dr. Mickelsen will introduce the new device during the prestigious Stanford Biodesign New Arrhythmia Technologies Retreat.
