Discover our primary medical device systems engineered for highly complex cerebral and peripheral thrombectomy procedures, optimized for local neurological centers.
The Kingdom of Bahrain, with Muharraq at the forefront of its clinical infrastructural expansion, is witnessing a pivotal transformation in its cardiovascular and neurological healthcare delivery. As cardiovascular diseases and cerebrovascular emergencies account for a substantial percentage of ICU admissions in the region, the availability of advanced mechanical thrombectomy devices has transitioned from a specialized clinical asset to a fundamental public health necessity.
Clinicians at premier institutions such as the King Hamad University Hospital (KHUH) in Muharraq are adopting complex endovascular therapy (EVT) as the standard of care for acute ischemic stroke (AIS) caused by large vessel occlusions (LVO). This shift has catalyzed the demand for highly reliable, precision-engineered thrombectomy stent retrievers and aspiration systems. The local medical ecosystem requires clinical tools that exhibit superior deliverability through tortuous cerebral anatomy, optimized radial force, and robust clot-capture capabilities to ensure high Recanalization rates (mTICI 2b/3) while minimizing the risk of vessel wall perforation or distal embolization.
The engineering behind modern thrombectomy stents relies heavily on Nitinol (nickel-titanium) shape memory alloys. Through high-precision laser cutting, these alloys are sculpted into complex cell architectures designed to interlock with soft, organized, or calcified thrombi. Our technical roadmap highlights key parameters that define superior mechanical thrombectomy performance:
Carefully calibrated radial outward force allows the stent retriever to expand within the thrombus, maximizing integration without causing arterial intima dissection.
Alternating open and closed-cell patterns provides high flexibility and ensures optimal kink resistance when navigating tight angles in the internal carotid artery (ICA).
Large internal diameter (ID) aspiration catheters maintain structural integrity under negative vacuum pressure, facilitating rapid single-pass clot extraction.
As vascular interventional surgeries increase in frequency across the Middle East, hospitals face the pressure of balancing clinical outcomes with procurement budgets. Our manufacturing base in Hangzhou, China, addresses this critical demand by integrating high-precision fabrication with an optimized supply chain, offering significant advantages over traditional European and American counterparts:
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. 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.
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.
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.
Our company is equipped with advanced production and inspection systems, including precision balloon forming equipment, laser welding and marking technologies, and comprehensive laboratory testing facilities. These capabilities ensure high levels of manufacturing accuracy, product consistency, and full-process quality control.
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. We continue to expand our international footprint and strengthen our global presence, with a particular focus on providing dedicated local support to the growing healthcare sector in the Gulf Cooperation Council (GCC) countries.
