SJ Medical
Chronic Total Occlusion (CTO) represents one of the most significant challenges in modern interventional cardiology. Defined as a complete or near-complete blockage of a coronary artery that has been present for at least three months, CTO requires specialized devices and high-level clinical expertise to navigate. As a leading CE Certified Chronic Total Occlusion Devices Factory, Hangzhou SJ Medical Co., Ltd. is at the forefront of this technological revolution, providing the tools necessary for physicians to achieve high success rates in complex Percutaneous Coronary Interventions (PCI).
Our commitment to E-E-A-T principles ensures that every microcatheter, guidewire, and balloon catheter we produce meets the rigorous demands of global healthcare systems. By providing significant information gain through our R&D, we help medical professionals understand the nuances of antegrade and retrograde approaches, ultimately improving patient outcomes in cases previously deemed "untreatable."
Located in Hangzhou, our facility leverages China's world-class medical device supply chain, ensuring rapid prototyping and scalable production of high-precision vascular tools.
We offer premium medical devices that meet European CE standards at a competitive price point, allowing hospitals to manage budgets without compromising patient safety.
Our engineers specialize in hydrophilic coatings and nitinol core technologies, essential for the "crossability" of devices in calcified CTO lesions.
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.
There is a global shift from CABG (Open Heart Surgery) to complex PCI. CTO devices are the primary enablers of this transition, reducing recovery time from weeks to days.
Integration of AI in imaging (IVUS/OCT) is helping doctors choose the right guidewire stiffness. Our devices are designed to be highly radiopaque for better visibility under AI-enhanced fluoroscopy.
The next generation of CTO treatment involves drug-coated balloons (DCB) to prevent restenosis after the initial crossing of the occlusion.
| Device Category | Key Technology | Clinical Application |
|---|---|---|
| Microcatheters | Braided Stainless Steel / Nitinol | Support for guidewire exchange and lesion crossing. |
| CTO Guidewires | Tapered Tip & Hydrophilic Coating | Penetrating tough fibrous caps and calcified lesions. |
| Balloon Catheters | High-Pressure Non-Compliant (NC) | Pre-dilation of rigid occlusions before stenting. |
Our products are currently distributed in countries such as Finland, Italy, Spain, France, the Netherlands, India, Indonesia, Turkey, and Egypt. We understand that different regions have unique regulatory and clinical requirements.
Focus on CE MDR compliance and high-performance metrics for complex retrograde procedures in leading cardiac centers.
Emphasis on cost-effective bulk supply and training support for emerging interventional cardiology departments.
Reliable logistics and robust device design capable of performing in diverse clinical environments with varying infrastructure.
CTO-specific devices, like specialized microcatheters and high-gram-force guidewires, are designed with enhanced torque control, tip stiffness, and lubricity to penetrate blockages that standard PCI tools cannot cross.
