WeMed Medical's Endovascular Robotic System Has Obtained NMPA Certification
On March 21, 2025, the National Medical Products Administration (NMPA) officially approved the launch of WeMed's ETcath® Interventional Surgery Assistance System. This marks the introduction of the world's first interventional surgery robot integrating "eye-hand-brain" functionality, signaling China's historic transition from "catching up" to "leading" in the field of high-end medical equipment.
ETcath® has achieved the first-ever data closed-loop across three major systems
Eyes: The self-developed DSA equipment is deeply integrated with AI algorithms to precisely capture every detail of vascular lesions, providing the robot with an "ultra-high-definition road map."
Hands: With the intelligent bionic expertise of an Endovascular Robotic System, it acts as a "vehicle" navigating through blood vessels. Under the doctor's remote control, it flexibly and precisely performs various complex surgical procedures, supporting the full interventional process of catheters, guidewires, balloons, and stents.
Brain: Through deep learning and big data analysis, the AI imaging platform not only supports a wide range of advanced image post-processing functions but also provides doctors with accurate diagnostic insights and treatment plans, effortlessly enabling "autonomous navigation" within blood vessels.
The advantages of Eye-Hand-Brain Solution:
▍ Provides surgeons with a fully integrated, immersive robotic surgery workspace.
▍ High-definition imaging, precise hand control, and an autonomous decision-making system that integrates underlying data, ensuring real-time performance and highly collaborative intelligence.
▍ Establishes an AI reinforcement learning platform based on imaging data and surgeon behavior, advancing toward a more intelligent operating system.
The First Domestic Model! A Remarkable Journey from Follower to Leader
On October 8, 2021, a pivotal moment in the development of cardiovascular interventional technology in China and globally occurred. With the support of the leadership at Beijing Anzhen Hospital, Capital Medical University, Professor Zhou Yujie's team successfully performed a special PCI procedure using the ETcath interventional surgery robot. This marked the first percutaneous coronary intervention (PCI) surgery performed by a domestically developed vascular intervention robot, signifying the transition of interventional surgery from the "manual era" to the "intelligent era."
A Leading Number of Patents
WeMed is committed to independent research and development, with ongoing large-scale investments. The company has secured hundreds of patents, 80% of which are invention patents. In the field of interventional surgery robotics, WeMed has established a comprehensive patent portfolio across the entire technology chain and is dedicated to creating the world's largest patent pool for interventional robotics.
Setting the Standard! Defining the Industry's "China Rules"
As one of the drafters of the national standard for interventional surgery robots, WeMed was the first to comprehensively define key performance metrics, such as axial movement and rotation, for interventional surgery robots. The company also established detailed safety features, including mechanical protection and collision avoidance, thereby setting new standards for the industry.
The First Domestic Interventional Robot to Validate Safety Through Controlled Trials!
ETcath® is the first domestic interventional surgery robot to conduct a "prospective randomized controlled clinical trial (RCT)." The trial was completed in five top-tier Grade A tertiary hospitals, including Beijing Anzhen Hospital, Capital Medical University. As the first clinical randomized controlled trial for an interventional surgery robot, the data is more rigorous, scientific, and authoritative. The trial results became a key basis for approval by the National Medical Products Administration (NMPA). In addition to evaluating safety and efficacy, the trial thoroughly validated the clinical effectiveness of advanced features, including force feedback.
The launch of ETcath® represents a major milestone in the field of medical technology. This innovative interventional surgery robot introduces advanced capabilities that enhance precision and efficiency in complex procedures. Designed to meet the growing demands of modern healthcare, ETcath® is poised to revolutionize the way interventional surgeries are performed, offering enhanced safety, improved patient outcomes, and a more intelligent approach to medical treatment. This launch not only showcases cutting-edge technological advancements but also marks a significant step forward in the evolution of surgical robotics.
