Pulse Biosciences, Inc. Appoints Dr. Gan Dunnington as Chief Medical Officer

Leading Cardiothoracic Surgeon Joins Leadership Team as the Company Leverages its Proprietary nsPFA™ Technology for the Treatment of Atrial Fibrillation

HAYWARD, Calif.--(BUSINESS WIRE)-- Pulse Biosciences, Inc. (Nasdaq: PLSE), Pulse Biosciences, Inc. (Nasdaq: PLSE), a company leveraging its novel and proprietary nanosecond pulsed field ablation (nsPFA™) technology for the treatment of atrial fibrillation, today announced the appointment of Gansevoort “Gan” Dunnington, M.D. as its Chief Medical Officer.

“On behalf of the Company, I am thrilled to welcome Dr. Dunnington to the Pulse Biosciences team,” said Kevin Danahy, Chief Executive Officer of Pulse Biosciences. “Dr. Dunnington brings a wealth of knowledge, expertise, and experience in the field of cardiothoracic surgery, where he is a leader in pioneering novel less-invasive technologies that improve the lives of patients with atrial fibrillation. We look forward to his leadership and contributions, as we continue to harness the power of nanosecond pulsed field ablation to have a significant and meaningful positive impact on the treatment outcomes of atrial fibrillation, all the while being increasingly patient and physician friendly.”

Dr. Dunnington is a cardiothoracic surgeon and the Director of Cardiothoracic Surgery at St. Helena Hospital (Napa Valley). He specializes in minimally invasive complex cardiothoracic procedures including the Hybrid Cox-Maze procedure for the treatment of atrial fibrillation (AF). Prior to his time at St. Helena Hospital, Dr. Dunnington was an assistant professor at Stanford University and assistant director of cardiothoracic surgery at El Camino Hospital, a Stanford University affiliate. Dr. Dunnington obtained his medical degree from the Medical College of Virginia. He completed his residency at Stanford University, where he served as Chief Resident of Surgery, and completed a fellowship in cardiothoracic surgery at the University of Virginia.

“I believe nsPFA can meaningfully advance the treatment of AF for patients,” said Dr. Dunnington. “Based on my experience using this technology in preclinical studies, I believe the differentiated mechanism of action has the potential to significantly improve the safety and efficacy profile of cardiac ablation procedures and to disrupt the AF surgical device market. I am excited to join the Pulse Biosciences team at this important stage of the product and look forward to helping to bring this novel and uniquely differentiated technology to patients and healthcare providers around the world.”
