SJ Medical
Premium medical device solutions engineered to navigate complex calcified lesions, optimized for clinical pipelines in the Antwerp region.
High-frequency transmission wire optimizing micro-motor rotational stability in orbital and rotational atherectomy cutters.
Transition-optimized hub and dilator system designed for smooth vessel entry and minimized access-site trauma.
Diagnostic handheld scanner facilitating high-resolution visualization of stenosis and plaque structure in carotid and peripheral arteries.
Engineered with a low entry profile and high crossability for calcified stenosis dilatation prior to stent placement.
In the treatment of modern vascular diseases, the management of heavily calcified arterial lesions remains one of the primary obstacles for clinical success in percutaneous coronary intervention (PCI) and peripheral vascular procedures. As Antwerp continues to cement its role as a key biomedical hub within the Flanders region and broader European health landscape, local cath labs and research centers—such as those linked to the University Hospital Antwerp (UZA) and ZNA hospital network—require advanced atherectomy platforms to safely alter plaque morphology before balloon angioplasty and stenting.
Atherectomy systems, utilizing rotational, orbital, directional, or laser mechanism pathways, require precision-machined elements to navigate tortuous anatomical vessels. As a leading manufacturer and strategic supplier, Hangzhou SJ Medical Co., Ltd. provides essential interventional components that conform to the stringent technical and regulatory expectations of clinicians in the Antwerp market.
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.
Equipped with precision laser welding, balloon forming, and mechanical verification chambers.
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.
Antwerp is not only a major metropolitan clinical market but also serves as the logistical gateway to Europe via the Port of Antwerp-Bruges. This makes the region a critical pivot point for the import, sterilization validation, and distribution of medical grade micro-components. SJ Medical coordinates closely with logistics channels to guarantee supply chain stability for hospitals and OEM clients across Belgium, Germany, and the Netherlands.
| Interventional Category | Technical Challenge | SJ Medical Solution Pathway | Antwerp Clinical Utility |
|---|---|---|---|
| Atherectomy Drive Units | High torsional stress & heat generation in micro-motors. | High conductivity copper-clad steel core wire. | Enables safe, prolonged rotation without thermal vessel damage. |
| Lesion Crossing | Tortuous calcified lesions in peripheral arteries (BTK). | 0.014" sterilized guidewires with hydrophilic coating. | Optimized pushability and steering for Flanders CLI registries. |
| Vessel Access | Vessel spasm and dissection risk during sheath entry. | Hydrophilic-coated, transition-free introducer sheaths. | Reduces vascular complications in outpatient cath labs. |
By leveraging our strong R&D division, we enable localized adaptions of vascular catheters. Antwerp medical institutions require devices that adhere tightly to the European Medical Device Regulation (EU-MDR 2017/745). Our robust documentation processes and compliance systems ensure seamless integration into local clinical trial architectures and commercial hospital procurements.
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 and regulatory requirements. The company has obtained CE certification, ISO 13485 quality management system certification, and CFDA approval, along with free sale certificates, demonstrating its strong commitment to product quality and compliance.
The 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. The company continues to expand its international footprint and strengthen its global presence.
SJ Medical is committed to providing comprehensive and professional services throughout the entire customer journey. From pre-sales consultation and technical support to efficient order processing and responsive after-sales service, the company ensures that every customer receives timely assistance and reliable solutions.
The future of vascular calcification management lies in hybrid techniques. By integrating traditional rotational ablation with shockwave-generating Intravascular Lithotripsy (IVL), clinical operators can address both superficial calcium and deep medial calcium layers. SJ Medical is actively aligning its engineering pipelines to support next-generation devices with:
