Engineered for high-rate recanalization and optimal radial performance in acute ischemic stroke and peripheral arterial interventions.
Cardiovascular and cerebrovascular pathologies, particularly acute ischemic stroke (AIS), present a massive public health challenge across the Korean Peninsula. In North Korea, major general hospitals and research centers such as the Pyongyang Medical College Hospital and Red Cross General Hospital have historically sought to enhance their neurological treatment protocols. However, the domestic production of high-precision cardiovascular intervention tools, particularly Class III mechanical thrombectomy (MT) devices, remains exceptionally constrained due to systemic resource bottlenecks and limitations in raw material processing.
Domestic manufacturing of vascular devices requires ultra-fine laser micromachining, medical-grade nickel-titanium (Nitinol) raw wire sourcing, and specialized chemical etching configurations. Consequently, North Korea's healthcare infrastructure relies heavily on import corridors, custom OEM sourcing, and technical partnerships with advanced manufacturing hubs in nearby China. For medical authorities and institutional procurers in the region, establishing secure supply chains for advanced stent retrievers and clot aspiration systems is paramount to ensuring immediate clinical intervention capabilities for life-threatening vascular obstructions.
Developing high-end vascular intervention systems demands highly controlled medical plastics extrusion and precision laser-welding, resources which regional factories cannot consistently implement. Partnering with a reliable adjacent supplier guarantees zero-interruption procurement.
Access to Nitinol laser-cut stent systems, which display shape memory and superelasticity, allows regional healthcare units to upgrade from outdated open surgeries to state-of-the-art minimally invasive procedures.
A trusted global leader in the R&D, manufacturing, and commercialization of vascular interventional medical devices.
Established in 2015, Hangzhou SJ Medical Co., Ltd. is dedicated to the research, development, manufacturing, and commercialization of vascular interventional medical devices. The company focuses on both cardiovascular and peripheral intervention fields, striving to provide safe, reliable, and innovative solutions for healthcare providers worldwide.
Over the years, SJ Medical has developed a comprehensive product portfolio covering key areas of vascular intervention. Its offerings span from various types of balloon catheters for coronary and peripheral applications to supporting access and diagnostic devices, as well as advanced stent systems. Through continuous innovation and strong R&D capabilities, the company has obtained multiple patents and international certifications, laying a solid foundation for sustainable growth in both domestic and global markets.
SJ Medical's GMP-compliant facilities house advanced laser cutting and balloon-forming machinery.
A profound look into our Nitinol laser cutting processing and stent-retriever physics.
Using ultra-fast laser processing systems to carve intricate mesh patterns on medical grade Nickel-Titanium tubing, ensuring zero heat-affected zones and preserving the core superelastic properties of the alloy.
Through proprietary thermal-shaping regimens, the Austenite Finish temperature ($A_f$) is precisely calibrated, enabling immediate expansion and excellent vessel wall apposition upon microcatheter deployment at body temperature ($37^\circ\text{C}$).
Our segmented design with varied cell densities offers exceptional thrombus engagement and superior retention during extraction, significantly minimizing fragment shedding and secondary embolization.
SJ Medical operates a state-of-the-art manufacturing facility covering approximately 5,000 square meters. The facility is fully structured according to stringent GMP standards. Within this campus, a 100,000-class cleanroom environment is combined with highly advanced localized 100-class sterile zones for critical production sequences.
Our facility integrates high-precision balloon forming equipment, advanced laser welding, and high-fidelity testing labs. These elements empower our cross-functional teams to secure extreme structural precision and uncompromising batch consistency, giving global clinical partners the trust and peace of mind they demand.
Solving complex distribution and quality bottlenecks for clinical demands worldwide.
Maintaining strong shipping networks via neighboring hubs helps us secure steady transit pathways to East Asian regions, minimizing custom delays and supply interruptions.
