Drug Eluting Stents

The ultrasonic drug-eluting stent spray coating system can be applied to the preparation of  polymer coating for preventing vascular restenosis on the surface of implantable drug-eluting stent. Compared to conventional two-fluid nozzles, ultrasonic nozzles can spray a more uniform drug coating that completely covers the stent without the orange peel and adhesion to a complex stent. In addition, the stent coating obtained by ultrasonic spray coating technology is thinner than dip-coating. Ultrasonic spray coating technology can precisely control the amount of drug sprayed on the stent, making the control of the spraying more precisely.

With more than 30 years of experience in the application of ultrasonic technology, Siansonic provides a variety of ultrasonic spray coating products and solutions for the manufacturing industry of implantable, interventional medical devices, the drug-eluting stents and balloon catheters. 

The ultrasonic drug-eluting stent spray coating system UC410, ultrasonic drug balloon catheter spray coating system UC520 combining various ultrasonic nozzles with independent intellectual property rights of our company can be applied to the spray and coating preparation of multiple implantable stents such as coronary stent , brain stent, peripheral stent and digestive tract, etc.
