Nature | Milli-spinner: Germany’s DeWei Medical Powers Stanford’s Zhao Ruikai Team to Achieve a Breakthrough in Thrombosis Treatment

On June 4, 2025, Professor Yilong Chang’s team from Stanford University (with Yilong Chang as the first author) published a groundbreaking research paper titled "Milli-spinner Thrombectomy" in the prestigious international academic journal *Nature*. The Milli-spinner thrombectomy technique leverages rotational forces to generate compressive and shear stresses, mechanically densifying the fibrin network within blood clots and significantly reducing their volume. This approach effectively addresses the longstanding challenge of removing large, fibrin-rich clots that are notoriously difficult for conventional mechanical thrombectomy methods to tackle. Both in vitro and in vivo experiments demonstrated that this innovative technology can rapidly and efficiently restore blood flow while maintaining excellent safety profiles. As a result, it holds immense potential for broad clinical applications—particularly in treating acute ischemic stroke and life-threatening conditions like pulmonary embolism, where timely revascularization is critical.

A new breakthrough in carotid plaque phantoms: Testing model lesions with custom-tailored elastic modulus.

In the field of medical technology, even a micrometer-level error can determine the course of life. Atherosclerosis is a chronic condition that begins with lipid metabolism abnormalities, leading to inflammation within the vessel lumen, intimal necrosis, and fibrosis—ultimately resulting in plaque formation at specific sites along the arterial walls. Over decades of gradual progression, these plaques may trigger acute cardiovascular or cerebrovascular events such as stroke or myocardial infarction.

DeWei All-Brain Silicone Vascular Model: Technology Empowers DSA Angiography Research

Cerebrovascular diseases significantly contribute to global mortality and long-term disability (Vaduganathan et al., 2022). In recent years, thanks to advances in medical and imaging technologies, the mortality rates associated with intracranial arterial (IA) diseases—such as intracranial artery stenosis (ICAS), middle cerebral artery occlusion (MCAO), and intracranial aneurysms—have declined (Hess, 2018).

Endoscopic Intervention Urology System Model – Customizable Simulation Silicone Intervention Model

Urinary tract stones are a common condition in urology. As early as 1901, stones were discovered in the pelvic bones of mummies from ancient Egyptian tombs. Today, they account for 6% to 10% of all urinary system disorders, and their incidence has been steadily rising in recent years, placing a significant burden on healthcare systems worldwide.

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.

Coronary Intervention Vascular Model – Minimally Invasive Interventional Device Testing

The heart is often referred to as the body's "perpetual motion machine," and any heart-related condition should not be taken lightly. Coronary artery disease, in particular, is a fairly common cardiovascular disorder. Officially known as coronary atherosclerotic heart disease, this condition essentially occurs when the blood vessels that supply the heart—known as coronary arteries—become narrowed or blocked due to various factors. This restricts the flow of blood to the heart muscle, leading to ischemia, oxygen deprivation, or even tissue death. As a result, patients may experience symptoms like angina or, in severe cases, even sudden cardiac arrest and death.
