[Product Collection] 03 Simulation Model – Neurointerventional Vascular Model | Mimic Blood Vessels, Delivering Precision-Driven Insights

In the treatment of cerebrovascular diseases, conditions such as intracranial aneurysms, cerebral arteriovenous malformations (AVMs), acute ischemic stroke, and carotid artery stenosis often rely on neurointerventional procedures. Intracranial aneurysms are treated with coil embolization or stent-assisted embolization to prevent rupture and bleeding, while cerebral AVMs are managed by using embolic materials to block abnormal blood flow. Acute ischemic stroke requires the use of thrombectomy stents or aspiration catheters to reopen blocked vessels. And in cases of carotid artery stenosis, balloon angioplasty combined with stent placement is employed to restore proper blood flow.

[Product Collection] 03 Simulation Model – RF Ablation Heart Model | Cardiac RF Intervention Simulation

The advent of cardiac radiofrequency ablation stems from humanity's relentless pursuit of effective treatments for arrhythmias. In the early 20th century, options for managing arrhythmias were limited: drug therapies offered inconsistent results, while surgical interventions carried significant risks and invasiveness. Patients urgently needed safer, more reliable treatment approaches. By 1940, breakthroughs in cardiac electrophysiology revealed that abnormal electrical activity in specific heart muscle tissues was the root cause of arrhythmias, paving the way for innovative therapeutic strategies in the years to come.

[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.

[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.

[Product Collection] 03 Simulation Model – Endoscopic Intervention Upper Gastrointestinal Tract Model | Accurately Replicates Physiological Details, Perfectly Recreating Digestive Scenarios

Upper gastrointestinal diseases encompass a wide range of pathological conditions affecting the esophagus, stomach, and duodenum, including infectious lesions (such as esophageal candidiasis, CMV-induced esophagitis, and HSV-related esophagitis), inflammatory disorders (like gastric ulcers and duodenitis), neoplastic conditions (including esophageal cancer, gastric cancer, and submucosal tumors), as well as acute bleeding episodes (such as ruptured varices or ulcer-related hemorrhage). These conditions often present with diverse clinical symptoms, and some early signs may be subtle or even absent. Without timely intervention, they can progress into life-threatening emergencies or malignant tumors. For instance, acute upper gastrointestinal bleeding (UGIB) carries a mortality rate as high as 2%–15%, and the accuracy of predicting the need for endoscopic intervention directly impacts treatment efficiency. Meanwhile, submucosal tumors of the digestive tract (SMTs), due to their deep-seated location, are typically challenging to diagnose using conventional endoscopy alone, often requiring advanced techniques such as endoscopic ultrasound (EUS) for accurate identification.

TAVR heart model precisely simulates blood flow, driving innovation in surgical techniques.

The medical understanding and treatment of aortic stenosis (AS) have evolved significantly over centuries of exploration and advancement. In the early stages, little was known about its underlying pathological mechanisms—only by the 19th century, with advances in anatomy and pathology, did scientists begin to clearly link it to abnormalities in valve structure. By the mid-20th century, the advent of echocardiography allowed doctors to more accurately assess the severity of valve narrowing and evaluate cardiac function, dramatically improving diagnostic capabilities. In terms of treatment, early approaches relied primarily on medications to alleviate symptoms, though these methods offered only limited effectiveness.
