The global cardiopulmonary bypass (CPB) equipment market is undergoing a transformative shift. As the prevalence of cardiovascular diseases (CVDs) continues to rise—affecting over 500 million people worldwide—the demand for high-precision heart-lung machines and auxiliary interventional devices has reached an all-time high. Modern cardiac surgery no longer relies solely on "open-heart" procedures; instead, it has evolved into a sophisticated blend of minimally invasive techniques and hybrid operating room environments.
Today's top-tier factories and exporters are focusing on Information Gain: providing not just the hardware, but the clinical data and material science breakthroughs that ensure patient safety. From biocompatible coatings on oxygenators to the precision of micro-catheters, the industry is moving toward "Integrated Extracorporeal Life Support" (ECLS) solutions.
Hangzhou SJ Medical Co., Ltd. was established in 2015 and 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.
The shift toward smaller, portable CPB units allows for emergency life support (ECMO) in transport scenarios, significantly improving survival rates in acute heart failure cases.
Advanced hydrophilic and heparin coatings on catheters and sheaths reduce the risk of thrombosis and inflammatory responses during prolonged procedures.
Integration of real-time monitoring and AI algorithms to predict perfusion requirements, minimizing human error in the operating room.
SJ Medical operates a modern manufacturing facility with a total area of approximately 5,000 square meters. The factory is built in accordance with GMP standards and features a high-standard cleanroom environment, including a million-class clean workshop with localized hundred-class areas for critical processes.
Our "Factory 4.0" approach integrates precision balloon forming equipment, laser welding, and automated inspection systems. This ensures that every PTCA Guidewire or Balloon Catheter meets the stringent requirements of the E.U. and U.S. markets. Supply chain resilience is at our core; by centralizing R&D and manufacturing in Hangzhou, we provide a stable, cost-effective pipeline for global distributors.
The company is supported by a highly experienced technical team, many of whom have been engaged in the medical device industry for decades. Under the leadership of senior engineers, SJ Medical maintains strict quality control and continuously improves its manufacturing processes to ensure product reliability and consistency.
SJ Medical has established long-term partnerships with clients across Europe, Asia, the Middle East, and Africa. Its products are currently distributed in countries such as Finland, Italy, Spain, France, the Netherlands, India, Indonesia, Turkey, and Egypt. We understand that local application scenarios differ: while European markets prioritize high-end specialized stents, emerging markets focus on reliable, high-volume vascular access consumables.
Our products are widely applied in minimally invasive procedures involving both coronary and peripheral vascular systems. They play an important role in the diagnosis and treatment of vascular diseases, helping to improve procedural efficiency while enhancing patient safety and recovery.
SJ Medical strictly adheres to international quality standards. We have obtained CE certification, ISO 13485, and CFDA approval, ensuring global compliance.
