SJ Medical
London has solidified its position as a global epicenter for medical innovation, particularly in the field of Below-the-Knee (BTK) intervention. As the capital of the United Kingdom, London hosts a unique ecosystem where world-class academic institutions like Imperial College London and University College London (UCL) collaborate with leading NHS Trusts such as King's College Hospital and Guy's and St Thomas'. This synergy has fostered a burgeoning industrial hub for vascular medical device manufacturing and export.
The demand for BTK interventions in London is driven by a sophisticated healthcare infrastructure focusing on Chronic Limb-Threatening Ischemia (CLTI) and diabetic foot complications. Local factories and exporters are not just suppliers; they are innovators integrating AI-driven diagnostics and precision engineering into peripheral vascular tools. From the Harley Street Medical Area to the tech clusters in East London, the city provides a fertile ground for developing high-specification balloon catheters, guidewires, and prosthetic solutions that meet the rigorous standards of the European and global markets.
Hangzhou SJ Medical Co., Ltd., established in 2015, stands at the forefront of the research, development, and manufacturing of vascular interventional medical devices. While our roots are deep in innovation-led manufacturing, our reach extends to major medical hubs like London, where our products support high-stakes cardiovascular and peripheral interventions.
Our comprehensive product portfolio is designed to address the complexities of vascular diseases. We offer everything from advanced balloon catheters for coronary applications to specialized supporting access devices. By maintaining a strong R&D focus, we have secured multiple international patents, ensuring that our London-based partners and global exporters receive only the most reliable and innovative solutions.

The shift towards ultra-low profile catheters allows for distal access in the foot, reducing trauma and accelerating recovery times for London patients.
Next-generation Drug-Coated Balloons (DCB) are becoming the gold standard in London clinics to prevent restenosis in small-vessel BTK procedures.
Integration of AI in fluoroscopy and IVUS helps surgeons in London navigate complex occlusions with unprecedented accuracy.
Our manufacturing prowess is anchored by a modern 5,000 square meter facility built strictly to GMP standards. To serve the high-end London medical market, we utilize a million-class clean workshop with localized hundred-class areas for critical assembly processes. This ensures that every BTK guidewire and catheter is free from contaminants and performs flawlessly in clinical settings.
Equipped with precision balloon forming equipment and laser welding technology, our factory maintains a level of consistency that London's leading vascular surgeons demand. Our technical team, led by industry veterans, oversees a rigorous quality control process that mirrors the stringent requirements of the UK's MHRA and European CE certifications.
In London, BTK interventions are critical in the management of the "Diabetic Foot." With a rising prevalence of Type 2 diabetes in urban centers, specialized clinics across Greater London utilize our interventional safety systems and guidewires for limb salvage procedures. These tools are essential for revascularizing the tibial and peroneal arteries, preventing amputations, and improving the quality of life for thousands of Londoners.
Furthermore, our rehabilitation equipment, such as the Lower Limb CPM and Air Compression Therapy Systems, are widely adopted by London-based physiotherapy centers. These devices facilitate post-operative recovery, ensuring that patients who undergo BTK stenting or angioplasty regain mobility faster and with fewer complications.
SJ Medical has established a robust presence across Europe, with London serving as a key hub for our Western European operations. Our products are exported to Italy, Spain, France, and the Netherlands, backed by CE, ISO 13485, and CFDA certifications. This global footprint is a testament to our commitment to quality and compliance, ensuring that our partners in London receive products that are not only innovative but also fully regulated and safe for clinical use.
