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.
