Ruidi Biotechnology’s newly certified Nanosecond Pulsed Ablation System is primarily indicated for solid tumors throughout the body, a category of diseases characterized by a large patient population, significant health burden, unmet clinical needs with existing therapies, and global attention.
Technically, compared with the ablation technologies currently on the market that use thermal or cryogenic energy, pulsed field technology offers advantages such as tissue selectivity, extremely short transmembrane time, and no accumulation of Joule heat. Therefore, it can break through the contraindications of traditional surgery and thermal/cryogenic ablation, enabling safe ablation in high-risk anatomical sites such as hepatocellular carcinoma in the hepatic hilum with dense vasculature and pancreatic cancer.
Furthermore, compared with the previous generation of kilovolt-level microsecond pulses, the nanosecond pulses developed by Hangzhou Ruidi Biotechnology Co., Ltd. have achieved multiple independent innovations. The voltage generated by its nanosecond pulse ablation system exceeds 10,000 volts, with a pulse width at the nanosecond level. These ultra-high-voltage, ultra-short pulses can traverse cell membranes and enter the nucleus, achieving superior ablation efficacy. To date, Hangzhou Ruidi Biotechnology has secured hundreds of core patents.
In fact, not only has the U.S. FDA recognized Hangzhou Ruidi Biotechnology Co., Ltd.’s nanosecond pulsed ablation system, but the National Medical Products Administration (NMPA) of China had already included Ruidi’s products in the Special Review Procedure for Innovative Medical Devices—commonly known as the “green channel”—as early as 2020. Having successively obtained both the Chinese Innovative Medical Device designation and the U.S. FDA Breakthrough Device designation, Ruidi Biotechnology’s nanosecond pulsed tumor ablation system has becomeThe World’s Only Tumor Pulsed Field Ablation System with Dual “Innovative” Designations in Both China and the United States。
The innovative designations granted by regulatory authorities in China and the United States will accelerate the approval of Hangzhou Ruidi Biotechnology Co., Ltd.’s nanosecond pulsed tumor ablation system by both the NMPA and the FDA. Additionally, Ruidi Biotechnology has successfully completed key milestones, including CE certification and manufacturing process transfer, thereby laying a solid foundation for global commercialization following its dual submissions in China and the U.S.
Notably, in addition to its nanosecond pulsed tumor ablation system for oncology applications, Hangzhou Ruidi Biotechnology Co., Ltd. has developed a Pulsed Field Ablation (PFA) system for atrial fibrillation based on its next-generation nanosecond electric pulse ablation technology platform. This product was also approved by the National Medical Products Administration (NMPA) at the end of 2023 to enter the Green Channel for innovative medical device review.
Leveraging its pioneering nanosecond pulse technology, Ruidi Biotechnology has secured two innovation designations from China’s National Medical Products Administration (NMPA) and one Breakthrough Device Designation from the U.S. Food and Drug Administration (FDA).
