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: Innovative Applications of Medical Simulation Models
In today’s rapidly advancing medical technology landscape, interventional devices—now the cornerstone of modern minimally invasive treatments—are undergoing unprecedentedly rapid iterations and updates. For device manufacturers, a high-quality interventional device showroom is not just a showcase for their products; it also serves as a vital platform to demonstrate technological expertise and attract both partners and potential customers.
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).
In May 2024, at the invitation of the Neurointerventional Hemodynamics Research Group at Stanford University in the United States.
In May 2024, at the invitation of the Neurointerventional Hemodynamics Research Group at Stanford University in the U.S., Derui Medical successfully completed the delivery of its next-generation bionic cerebral vascular phantom and advanced hemodynamic testing equipment. The system has received unanimous praise from both Stanford University and leading neurointerventional physicians in the U.S., addressing critical challenges encountered during cerebral vascular intervention procedures.
In June 2023, DeWei Medical successfully delivered the cardiac intervention device delivery testing system to HeartPath Medical Technology (Guangzhou) Co., Ltd.
In June 2023, Dermed Medical successfully delivered the cardiac intervention device delivery testing system to Heartway Medical Technology (Guangzhou) Co., Ltd., a rising star in China's cardiac intervention device industry.
In April 2023, DeWei Medical successfully delivered the ECMO mock-up testing system to the Human Pulmonary Circulation Project Team at Fuwai Hospital, Chinese Academy of Medical Sciences.
In April 2023, DeWei Medical successfully delivered the ECMO phantom testing system to the Human Pulmonary Circulation Project Team at Fuwai Hospital, Chinese Academy of Medical Sciences, completing China's first-ever in-vitro validation experiment for ECMO equipment—and addressing a key scientific challenge encountered during ECMO cannulation procedures.
In November 2022, Derui Medical successfully developed a particle/re-transmission testing system for pan-vascular interventional devices.
In November 2022, DeWei Medical successfully developed a particle/re-coating testing system for pan-vascular interventional devices. This solution addresses the critical need for in-vitro particle and re-coating validation of various pan-vascular interventional tools, including drug-coated balloons, drug-eluting stents, coated catheters, and coated guidewires.
