Renal Artery Denervation (RDN) represents one of the most significant clinical advancements in interventional cardiology and nephrology. By targeting hyperactive sympathetic nerves in the adventitia of the renal arteries, RDN offers a durable, device-based approach to lowering blood pressure in patients diagnosed with resistant and uncontrolled hypertension.
Uncontrolled hypertension is a leading contributor to cardiovascular mortality, cerebrovascular accidents, and chronic kidney disease (CKD) worldwide. Traditional management has relied heavily on multi-drug pharmacological regimens. However, clinical adherence is historically low, and many patients exhibit drug resistance. RDN addresses this gap by utilizing catheter-based radiofrequency (RF) energy or high-intensity ultrasound to safely and selectively ablate the renal sympathetic nerves.
As a leading developer of vascular interventional medical devices, we specialize in high-precision balloon catheters, access systems, and guide sheath configurations necessary to support and navigate the tortuous paths of renal artery anatomy during denervation and related interventional procedures.
Global regulatory bodies, including the US FDA and CE marking systems, have granted clearances for next-generation RDN systems. This has spurred massive investments in specialized accessories like biocompatible access sheaths, steerable guide catheters, and high-performance renal dilators.
The manufacturing of vascular catheters requires class-leading extrusion tech, hydrophilic coating capabilities, and absolute compliance with GMP standards. Leading manufacturers emphasize the integration of tracking, pushability, and kink-resistance in interventional toolsets.
The rise of global cardiovascular disease prevalence, combined with an increasing preference for minimally invasive day-care interventional procedures, is driving double-digit CAGR growth in renal interventional markets globally.
In developing regions like Malakal (the capital of Upper Nile State, South Sudan), the medical supply chain faces unique logistical and clinical challenges. Cardiovascular disease management is transitioning from emergency-only care to systematic monitoring and intervention. As clinical institutions in Malakal build their dialysis capacities and diagnostic labs, securing high-quality, durable vascular access products and nephrology equipment is vital.
Key hospitals and humanitarian healthcare providers operating in Malakal require reliable medical partners who can guarantee stable shipping channels, robust quality control certificates, and user-friendly medical devices. Developing local clinical capacity involves a dual approach: introducing durable clinical training models (such as renal anatomical structures) and deploying high-precision surgical instruments, dialyzers, and fluid management accessories.
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.
SJ Medical focuses on the development of vascular interventional devices designed for both coronary and peripheral procedures. Its product range integrates interventional access systems, diagnostic catheters, and therapeutic devices, forming a complete solution for minimally invasive vascular treatments. Each product is developed with an emphasis on precision, safety, and clinical performance, aiming to support physicians in achieving optimal procedural outcomes.
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 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.
Providing high-class interventional components is only the first step. SJ Medical focuses on bringing comprehensive solutions to health systems, facilitating access even in developing nodes like Malakal. Our R&D pipeline focuses on three developmental fronts:
Our technical team is continuously optimizing the diameter profile and surface friction of access sheaths. Lowering entry resistance ensures minimal arterial wall damage, reducing procedural complications in peripheral vascular pathways.
Using next-generation thermal management extruders, we ensure that our dilators and catheters have consistent durometer sections. The gradient transition from rigid proximal shafts to highly flexible distal tips allows smooth anatomical tracking.
Recognizing the challenging supply chain conditions in Malakal, we provide climate-stabilized multi-layer barrier packaging to protect polymer compounds against ambient humidity and temperature changes during extended transit.
Renal access sheaths provide a stable pathway from the femoral or radial puncture site to the main trunk of the renal artery. They shield the arterial vessel walls from friction, prevent kinking during catheter navigation, and allow contrast media injection to verify the target ablation zone.
Yes. We offer fully compliant OEM/ODM services for our complete line of vascular access accessories, dilators, and dialysis consumables. We handle required documentation support (CE Mark, ISO certificates, Free Sale Certificates) to facilitate smooth customs clearance in East African markets.
We operate in strict accordance with ISO 13485 and local GMP guidelines. Our modern facility includes automated micro-catheter assembly systems, laser-welded joint technologies, and 100% video inspection systems for tip dimensions and concentricity.
Standard manufactured items depend on production schedules, but generally ship within 4 to 6 weeks. Customized bulk production batches are scheduled dynamically, and we provide transparent tracking via air/ocean freight corridors serving local partners in Malakal.
