Project Description

Balloon Catheter Spray

In 1977, Swedish doctor Gruentzing successfully performed the first percutaneous transluminal coronary angioplasty (PTCA), marking the beginning of interventional medicine. As a young and energetic professional technique, interventional therapy has attracted more and more people’s attention for its advantages of small trauma, safety, and reliability. In the past 30 years, especially in the past 10 years, interventional therapy has developed rapidly. According to statistics, about 2.5 million patients worldwide have received coronary interventional therapy. At the same time, the scope of interventional therapy has evolved from the original coronary artery (PTCA) to intracranial nerves, carotid arteries, renal arteries and veins, and even almost all blood vessels in the body (PTA).

As one of the main instruments of intracavitary interventional therapy, the balloon catheter is not only used for the pre-dilation and shaping of blood vessels, but also the delivery platform of stents, as well as the precise shaping after stent placement. It is important in interventional therapy. As the heart of balloon catheters, medical balloons have always been one of the focuses of catheter design, development, and performance optimization. The drug-eluting balloon, which combines traditional balloon expansion technology with the latest drug release technology, has attracted more and more attention due to its advantages such as intervention without implantation, no risk of thrombosis, and rapid treatment effect. The effect of the drug-eluting balloon is similar to that of the drug-eluting stent. It can uniformly deliver the anti-proliferative drug coated on the surface of the balloon to the patient’s blood vessel wall, thereby inhibiting intimal hyperplasia and reducing the occurrence of restenosis in the stent Rate.

UAM7000 is an ultrasonic spraying equipment specially designed for drug eluting balloons. It provides a uniform drug coating for the balloon catheter through ultrasonic spray technology. UAM7000 can also be used to adjust and control the deposition process of drug coatings for different liquid formulations. With the help of a special fixing device design, the entire balloon catheter can be sprayed with a maximum spraying length of 280 mm., It also has the functions of solvent doping, pre-heating, humidity control, and drying. The equipment has the characteristics of precise application amount, uniform film layer, and high utilization rate of chemical liquid. Cheersonic has extensive experience in surface coating of implantable medical devices (such as drug stents and balloons), and can provide customers with complete solutions.
