The global vascular interventional market is witnessing a paradigm shift from traditional open surgery to Endovascular Aneurysm Repair (EVAR) and Thoracic Endovascular Aneurysm Repair (TEVAR). As a leading manufacturer in China, Hangzhou SJ Medical Co., Ltd. stands at the intersection of medical engineering and clinical necessity. Stent grafts represent a critical component in the treatment of aortic aneurysms, dissections, and peripheral arterial diseases.
Modern stent grafts are no longer simple scaffolds. The industry is moving towards ultra-low profile delivery systems, customized fenestrated grafts, and bio-compatible PTFE coatings. These innovations allow surgeons to treat complex anatomies that were previously considered "inoperable," significantly reducing procedure time and improving patient outcomes through minimally invasive access.
The aging global population and rising prevalence of cardiovascular diseases drive the demand for reliable stent graft suppliers. China's manufacturing sector has evolved from basic assembly to high-end R&D, offering devices that rival Western counterparts in safety while providing superior cost-efficiency.
Our manufacturing utilizes aerospace-grade Nitinol and high-tenacity polyester/ePTFE fabrics. By integrating laser precision cutting with automated balloon forming, we ensure that every micron of the device meets clinical tolerances.
Stent grafts must resist migration and endoleaks. Our proprietary "active fixation" mechanisms and proximal sealing technologies are designed to withstand the high-flow hemodynamic environment of the aorta.
Hangzhou SJ Medical Co., Ltd. is dedicated to the research, development, and commercialization of vascular interventional medical devices. Our focus spans both cardiovascular and peripheral intervention, striving to provide innovative solutions for healthcare providers worldwide. Established with a vision to democratize high-end medical technology, SJ Medical has secured multiple patents and international certifications.
Unlike standard manufacturers, SJ Medical employs a Vertical Integration Strategy. We control the production from the raw Nitinol wire drawing to the final catheter sheath assembly. This ensures that every component—be it a coronary balloon catheter or a complex stent graft delivery system—maintains 100% traceability and performance consistency.
Transitioning toward bio-resorbable scaffolds and drug-coated delivery systems to minimize long-term chronic inflammation and improve vessel remodeling.
Implementing Femtosecond Laser Cutting and AI-driven quality inspection to detect microscopic defects in stent struts that human eyes might miss.
Development of "Steerable Sheaths" that allow clinicians to navigate tortuous iliac arteries with minimal vessel trauma, reducing the risk of access-site complications.
SJ Medical operates a high-standard cleanroom environment, including localized hundred-class areas for critical assembly processes. Our facility is equipped with precision balloon forming equipment and laser welding technology, ensuring that our stent grafts and catheters meet the rigorous demands of modern hemodynamics.
Navigating the regulatory landscape of medical devices requires deep expertise. SJ Medical holds CE Certification, ISO 13485, and CFDA (NMPA) approvals. We don't just ship products; we provide a localized support ecosystem for our partners in Europe, Asia, the Middle East, and Africa.
We provide comprehensive Technical Files (TF) and support for local registration in countries like India, Indonesia, Turkey, and Brazil.
Remote and on-site training for clinical specialists on the correct deployment of our stent systems and introducer sheaths.
Strategically located in Hangzhou, we leverage China's advanced logistics to ensure consistent delivery times even during global supply chain disruptions.
Our product portfolio is engineered for high-stakes medical procedures where precision is the only option:
