Pulse Biosciences Submits Two Devices for 510(k) Clearance to US FDA

Pulse Biosciences has recently announced two significant 510(k) submissions to the U.S. Food and Drug Administration (FDA), marking important milestones in the company’s expansion of its CellFX Nanosecond Pulsed Field Ablation (nsPFA) technology into new medical fields. The first submission, for the CellFX® nsPFA Cardiac Clamp, represents a novel approach to surgical cardiac ablation, designed to produce continuous linear transmural ablations during cardiac surgical procedures. This technology promises to deliver significant safety and performance benefits over existing thermal ablation technologies, potentially reducing procedure times and minimizing the risk of collateral damage to adjacent tissues. The company's leadership expressed confidence in the clamp's ability to set new standards in cardiac ablation, highlighting its nonthermal mechanism and the impressive preclinical data supporting its efficacy and safety.

In addition to the cardiac focus, Pulse Biosciences has also filed a 510(k) for its innovative CellFX® nsPFA percutaneous electrode, aimed at non-cardiac applications. This needle device leverages the precision of nsPFA energy to achieve complete nonthermal ablation of cellular tissue, sparing noncellular structures. The submission of these two 510(k)s, underscores the company's commitment to advancing medical treatment options across a broad spectrum of applications. Pulse Biosciences' leadership expressed enthusiasm for the potential for these technologies to significantly impact patient care and outcomes, signaling a robust growth trajectory for the company's proprietary nsPFA technology in both cardiac and non-cardiac fields. Neither device has yet been cleared by FDA and are for investigational use only.

Pulse Biosciences Appoints Dr. Niv Ad as Chief Science Officer, Cardiac Surgery

“After working with the Pulse Biosciences’ team and participating in preclinical studies using the nsPFA clamp for cardiac ablation, it was immediately clear to me that nsPFA has the potential to not only replace all other energy modalities in cardiac ablation, including radiofrequency and cryo, but due to the speed, safety, and ablation performance of the system, it has the potential to significantly expand the number of patients we treat in cardiac surgery,” said Dr. Niv Ad, Chief Science Officer, Cardiac Surgery. “Because of this and how far along the Company is in the development of a commercially viable system, I decided to join this experienced team as it enters this next exciting phase of bringing CellFXTM Technology from the lab to the clinic to make a positive impact on patient lives and healthcare. I look forward to working alongside this impressive team.”

Dr. Ad is a leading authority in surgical treatment of atrial fibrillation, minimally invasive heart surgery and other advanced heart surgery techniques and transcatheter therapies. Dr. Ad has published more than 200 research articles in peer-reviewed publications. He has led the development of national and international clinical practice guidelines for the different cardiovascular societies for ISMICS, AATS and STS, and serves on multiple leadership positions and committees in the leading cardiothoracic societies. He is the past president of The International Society of Minimally Invasive Cardiothoracic and Vascular Surgery (MICS), the leading entity for minimally invasive procedures globally and he is the Editor in Chief of INNOVATIONS: Technology and Techniques in Cardiothoracic and Vascular Surgery.

Our Technology

Our proprietary Nanosecond Pulsed Field Ablation (nsPFA) technology delivers nanosecond pulses of electrical energy to nonthermally clear cells while sparing adjacent noncellular tissue. nsPFA energy is delivered from the powerful and versatile nsPFA generator platform. The nsPFA platform was developed to be capable of connecting to multiple types of applicators from superficial to surgical to catheter-based therapies. Our system has already been used to treat over 6,000 patients safely and effectively outside of Cardiology.

These ultrafast electrical energy pulses have pulse durations from billionths up to a millionth of a second. When applied to targeted tissue, nsPFA energy pulses enter cells and alter the function of the internal cellular organelles, including the mitochondria and endoplasmic reticulum. The cascade of intracellular disruption leads to regulated cell death (RCD). RCD is a process exhibited by cells in the human body when they undergo stress and are unable to restore cellular homeostasis.

Pulse Biosciences has brought to market the first commercial product to harness the distinctive advantages of nsPFA technology.

Mechanism of Action

  • Nonthermal modality that delivers nanosecond duration pulses of electrical energy
  • Unlike thermal technologies, nsPFA energy directly impacts cellular structures while sparing non cellular tissue
  • nsPFA energy pulses initiate nanopores in cellular membranes that allow ions, such as calcium, to move within the cell
  • Triggers a cascade of intracellular disruption that stresses vital cell organelles
  • Breakdown of vital cell organelles leads to regulated cell death (RCD)
