SJ Medical
High-precision diagnostic, access, and therapeutic equipment developed within state-of-the-art ISO 13485 cleanroom environments.
Over the past two decades, the global clinical space has shifted from transfemoral access (TFA) to transradial access (TRA) in interventional cardiology and peripheral vascular therapies. This progression has been driven by randomized clinical trials proving that transradial access yields lower bleeding rates, faster mobilization times, reduced hospital lengths of stay, and superior patient comfort. In modern cath labs, access kits are the vital first contact point, dictating the overall success rate of subsequent procedures.
"Clinical consensus guidelines now universally recommend radial access as the default pathway for coronary angiographies and percutaneous coronary interventions (PCI), unless anatomical anomalies dictate otherwise."
For hospital systems, clinical procurement networks, and international distributors, partnering with a dependable, regulatory-compliant manufacturing facility is essential. Achieving optimal kink resistance, micro-puncture smooth transitions, and high biocompatibility requires deep polymer expertise and precise quality controls. High-performance radial access kits reduce entry failures and vessel spasm rates, protecting healthcare systems from elevated downstream costs.
The global interventional access market is projected to sustain a Compound Annual Growth Rate (CAGR) of over 7.5% through the next decade. As clinical interventions expand into neurovascular and deep peripheral applications via distal radial access points, the demand for thin-walled introducer sheaths has surged.
Geographically, manufacturing is highly consolidated. While North American and Western European entities focus heavily on proprietary, patented technology and clinical research, East Asian hubs—especially China—have developed robust industrial ecosystems. These centers deliver high-precision medical-grade extrusion, hydrophilic coating chemistry, and component assembly at scale.

Established in 2015, Hangzhou SJ Medical Co., Ltd. is a dedicated manufacturer, researcher, and commercial exporter of vascular interventional devices. The company provides reliable, high-performance, and clinically validated solutions for cardiovascular and peripheral access interventions globally.
By investing in technology and product design, SJ Medical has built an expansive portfolio. This ranges from diagnostic catheters and balloon dilatation catheters to advanced access components like introducer sheaths and dedicated drug-coated coronary stent systems.
SJ Medical operates an advanced 5,000-square-meter manufacturing plant configured in strict accordance with international GMP requirements. Key processes are managed in a Class 100,000 (ISO Class 8) cleanroom, with localized Class 100 areas to guarantee sterility for critical vascular contacts.
In the medical device industry, compliance is non-negotiable. SJ Medical operates under a certified ISO 13485 Quality Management System. The company's products carry CE marks, CFDA clearances, and Free Sale Certificates (FSCs), ensuring smooth importation and regulatory approval across global markets.
This strict quality approach applies to every step of production. Raw materials (including medical-grade PTFE, Pebax, and polyurethane) are sourced from top global chemical manufacturers. Each lot undergoes comprehensive incoming inspection, batch tracking, and post-sterilization analysis (via ETO validation) to guarantee safety and performance.
Global medical buyers look to China for production efficiency, structural cost control, and robust supply chain integration. The region offers several distinct advantages:
The vascular access landscape continues to advance. Manufacturers are focused on developing sheaths with ultra-thin walls to minimize arteriotomy size while preserving inner lumen diameter. Hydrophilic coatings are also evolving to reduce friction during placement and removal, mitigating the risk of arterial spasm.
Additionally, clinicians are increasingly adopting distal transradial access (dTRA) via the anatomical snuffbox. This approach requires shorter sheath transitions and dedicated micro-puncture components, representing a key focus area for SJ Medical's ongoing product development.
