SJ Medical
High-precision diagnostic and therapeutic catheters manufactured to international clinical standards.
Pioneering standard-compliant vascular access and therapeutic devices for international healthcare.
Hangzhou SJ Medical Co., Ltd., established in 2015, stands at the forefront of medical technology as a dedicated high-tech enterprise focusing on the research, development, manufacturing, and commercialization of class III vascular interventional medical devices. Our clinical engineering efforts span both the cardiovascular and peripheral intervention fields, striving to provide safe, reliable, and clinically progressive solutions for healthcare providers worldwide.
Over the years, SJ Medical has developed a comprehensive product portfolio covering key areas of vascular intervention. Our 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.
State-of-the-art cleanroom environment supporting high-precision extrusion, balloon forming, and laser processing.
SJ Medical operates a modern manufacturing facility built in accordance with global GMP standards to support raw material preparation, extrusion, and secondary assembly processes.
Features a million-class clean workshop (Class 100,000 cleanroom) integrated with localized class 100 areas reserved for high-sensitivity processes to guarantee zero pyrogen contamination.
Supported by a highly experienced technical team with decades of device R&D experience, leading QA engineers supervise strict quality checkpoints from feedstock validation to final sterilization.
Analyzing procurement strategies, total cost of ownership, and OEM/ODM system integration in interventional medicine.
In the contemporary healthcare landscape, procurement managers and hospital buyers must prioritize clinical safety, regulatory compliance, and cost-efficiency. Interventional radiology (IR) products, such as introducer sheaths, vascular access kits, and guidewires, form the backbone of modern catheterization laboratories. Sourcing these precision medical devices from verified Chinese manufacturers provides substantial cost benefits without compromising clinical outcomes.
SJ Medical addresses these needs by maintaining a robust quality management system (QMS) aligned with ISO 13485. Our high-volume manufacturing capabilities ensure a reliable supply chain, insulating global hospital networks from supply deficits. By integrating superior materials (e.g., medical-grade PTFE liners, hydrophilic coatings, and radiopaque platinum markers), our products deliver optimal trackability, crossability, and kink resistance during complex coronary and peripheral interventions.
International distributors require consistent lead times, customizable packaging options (OEM/ODM), and thorough registration dossiers. SJ Medical provides comprehensive regulatory files (CE, ISO, NMPA documentation) to expedite localized registration in the EU, Middle East, and Asia-Pacific regions.
For interventionalists, access is key. Our vascular access kits utilize ultra-thin walls to maximize inner diameters for accessory device passage, while maintaining structural integrity to resist kinking. The smooth transition from dilator to sheath minimizes puncture trauma and reduces procedural bleeding.
How material science, biodegradable polymers, and precision coatings are shaping next-generation IR equipment.
As interventional procedures shift toward more micro-invasive access points (e.g., distal radial artery access) and specialized neurovascular procedures, the technical demands on interventional equipment have intensified. Over the next five years, SJ Medical is dedicating its R&D pipeline to three core pillars:
Leveraging biodegradable polymers like Poly Lactic Acid (PLA) for tissue engineering scaffolds. These transient implants support vessel healing and then fully resorb, eliminating long-term foreign body responses.
Refining polymer-free elution technologies (e.g., Sirolimus-eluting platforms) to ensure target-dose drug delivery to prevent restenosis, without risk of polymer-induced chronic inflammation.
Developing sub-millimeter access profiles utilizing high-tensile stainless steel braiding and nitinol cores, allowing clinicians to safely access distal cerebral vasculatures.
Strict compliance with international standards ensures seamless local distribution and cross-border support.
SJ Medical has established long-term partnerships with clients across Europe, Asia, the Middle East, and Africa. Our products are currently distributed in countries such as Finland, Italy, Spain, France, the Netherlands, India, Indonesia, Turkey, and Egypt, among others. The company continues to expand its international footprint and strengthen its global presence.
Our regulatory team actively manages international compliance standards, ensuring all products bear necessary CE certification and comply with ISO 13485. Through our dedicated pre-sales consulting and post-sales technical support, we help clients navigate localized clearance, clinical trials, and training programs, maintaining the highest levels of device reliability and commercial confidence.
