Balloon catheter hydrophilic coating

Balloon catheter hydrophilic coating——Preparation of hydrophilic coating——Film spraying——Shanghai Yangmi ultrasonic spraying

When the balloon catheter enters the body, it causes a series of reactions. Such as catheter friction caused by vascular endothelial damage, bacterial adsorption, etc. In order to reduce the damage caused by balloon catheter during interventional therapy and improve the biocompatibility and lubricity of balloon catheter surface, hydrophilic energy is usually used to modify the surface of balloon catheter. An effective modification method is to cure a hydrophilic solution on the surface of the balloon catheter.

Balloon catheters can be used intravascular or in other procedures to facilitate minimally invasive access and treatment of the target site. An angioplasty catheter may include a balloon mounted on the catheter that can be advanced to the target site and inflated to clear or compress an obstruction, such as a stenosis. The stent delivery catheter may include a stent placed above a balloon that can be expanded to deploy the stent.

YMUS-DG300 is an ultrasonic spraying device specially used for drug coating of drug balloon catheter. It is equipped with a micro-ultrasonic nozzle or a converging ultrasonic nozzle to prepare the drug coating on the balloon catheter by ultrasonic spraying technology. It is characterized by accurate control of the dosage, uniform coating, no pinhole orange peel and other defects. Equipped with special balloon catheter fixture and rotating mechanism, it can be used for drug coating of coronary balloon, peripheral balloon and other kinds of drug balloon catheter. It is a widely used precision drug coating equipment for drug balloon.
