A medical catheter is a thin tube prepared primarily from medical materials (such as the medical plastics PVC, nylon, polyurethane and silicone rubber) that can be connected to other supplies and devices and inserted into the body or outside the body for the treatment or diagnosis of disease. These materials need to have good biocompatibility, corrosion resistance, flexibility, and a certain degree of strength. CD Bioparticles is able to provide semi-finished products such as microcatheters, angiography catheters, central venous catheters, hemodialysis catheters, and balloon catheters. Strict control of material purity and processing ensures the quality and safety of the catheters.
