    [Product Collection] 03 Simulation Model – Electrophysiological Heart Model | Electrophysiology Experiment Simulation Platform

    Electrophysiological heart models are closely linked to various cardiac arrhythmia disorders. Atrial fibrillation is a common condition in which patients experience disorganized electrical signals in the atria, increasing the risk of serious complications such as blood clots and heart failure. Clinically, catheter ablation is often employed as a treatment, using tools like mapping catheters and radiofrequency ablation catheters to precisely locate and eliminate abnormal electrical pathways. Ventricular tachycardia, meanwhile, is equally challenging; during an episode, the ventricles beat excessively fast, potentially leading to sudden cardiac arrest, necessitating procedures that combine mapping and ablation to restore normal heart rhythm. Additionally, atrioventricular block—a condition where electrical signals between the atria and ventricles are disrupted—can severely impair cardiac function, often requiring implantation of a pacemaker for effective management.

    Ministry of Finance: Government procurement projects for medical devices exceeding 45 million yuan should exclude EU-based companies (including policy Q&A interpretations).

    On July 6, 2025, China's Ministry of Finance issued a significant notice announcing restrictive policies on the import of medical devices. The policy stipulates that when procuring medical equipment with budget amounts exceeding 45 million RMB, buyers must exclude European Union-based companies (excluding EU-invested enterprises already operating in China) from participating—provided that importing products is deemed absolutely necessary after following the legally mandated procedures. Meanwhile, for non-EU companies involved, the proportion of medical devices sourced directly from the EU cannot exceed 50% of the total project contract value. The introduction of this policy has sparked widespread attention and intense debate across the medical device industry—and even throughout the broader economic sector. On July 10, the Ministry of Finance further released "Policy Q&A on Measures to Be Taken Against Medical Devices Imported from the EU in Government Procurement Activities," providing clear explanations addressing key questions about how the policy will be implemented, thereby offering more precise guidance for its effective application.

    [Product Collection] 03 Simulation Model – Left Atrial Appendage Occlusion Heart Model | Precise Deployment for Intuitive Evaluation

    [Product Collection] 03 Simulation Model – Left Atrial Appendage Occlusion Heart Model | Precise Deployment for Intuitive Evaluation

    Atrial fibrillation (AF) is a common cardiac arrhythmia seen in clinical practice, affecting over 40 million patients worldwide. During AF, blood flow within the left atrial appendage becomes sluggish, increasing the risk of clot formation. If these clots dislodge, they can travel to the brain, leading to stroke—a condition with extremely high rates of disability and mortality. Left atrial appendage closure has emerged as a critical strategy for preventing stroke in AF patients. This procedure involves placing a closure device into the left atrial appendage, effectively blocking the pathway that allows clots to enter the bloodstream. The surgery relies on specialized instruments, including delivery sheaths, guidewires, and dedicated occluders such as the Watchman or LAmbre devices. However, in real-world clinical settings, the left atrial appendage exhibits diverse anatomical shapes—ranging from "chicken-wing" to "cauliflower" or "windsock" types—and is closely situated near critical structures like pulmonary veins and coronary arteries. As a result, ensuring the stability of these devices in the complex intracardiac environment and achieving optimal apposition of the occluder during surgery remain challenging tasks that are difficult to predict preoperatively. Additionally, the varying sizes and irregular inner surfaces of the left atrial appendage mean that improper handling during the procedure could easily lead to serious complications, such as pericardial tamponade or device displacement—both of which demand exceptional spatial awareness and precise instrument control from the surgeon. Traditional training methods often fall short in replicating the true anatomical variations and surgical risks involved, making the development of realistic left atrial appendage closure heart models essential for overcoming these technical hurdles.
