In November 2022, DeWei Medical successfully developed a particle/re-coating testing system for pan-vascular interventional devices. This solution addresses the critical need for in-vitro particle and re-coating validation of various pan-vascular interventional tools, including drug-coated balloons, drug-eluting stents, coated catheters, and coated guidewires.

Introduction to the Pan-Vascular Interventional Device Particle/Reprint Testing System: The entire simulation system includes a vascular model compliant with the F2394 guideline standards (divided into two segments: the access vessel section and the target vessel section), a fluid environment simulation device (including a circulating temperature control system), and a fluid collection unit.
● Customized Vascular Structure for Access Routes
1. Coronary/neurovascular devices complying with the F2394 guideline standards, ensuring compliance in diameter, dimensions, and geometric shape;
2. 3D-printed blood vessels feature intricate, winding structures that are both typical and representative.
3. The special silicone material can replicate physiological features such as the elasticity of human blood vessels;
4. Highly transparent, making it easy to track the number of drug and device particles during use;
● Target Vessel Material Selection
The inner wall of the target vessel is equipped with a special adhesive coating that mimics the behavior of real vascular endothelium toward drugs.
● Circulating Temperature Control System
1. Equipped with a circulation pump to deliver fluids and simulate liquid flow and circulation;
2. When paired with a temperature control component, it can raise the fluid temperature and maintain a constant 37°C.
● Mechanism of action
Assemble the vascular model, set the temperature and flow rate to simulate blood conditions, then activate the fluid simulation device. After rinsing the model’s tubing thoroughly, insert the medical instrument into the vascular model until it reaches the target site. Once in place, flush the entire lumen of the vascular model, collecting the particle-containing fluid in a beaker and carefully counting the number of particulate samples.
