Balloons

It is widely recognized that using drug-eluting balloon catheters instead of drug-eluting stents is one of the potential treatments. As a leader in the industry, Cheersonic possesses more than 10 years of experience in the preparation of thin film coatings for medical implantable devices by using ultrasonic spray coating technology, especially for balloon catheter coatings.

Cheersonic ultrasonic spraying systems can deposit a uniform thin films of anti-restenosis drugs onto implantable devices such a cardiac and peripheral stents. Compared to conventional dip coating and two-fluid spray coatings, ultrasonic spray coating technology applied in balloon catheter coatings can produce a more uniform thin film coating. At the same time, the ultrasonic spray coating technology has the edges of strong controllability, the ability of manufacturing more stable preparation of thin film on balloon catheter and re-spray ability.

The CMED-M is a balloon catheter coating system designed to coat balloons up to 300 mm in length. A rotating cassette fixture holds one catheter up to 2 meters in length.

How it works: The balloon is inflated before painting. The rotating motor rotates the catheter and the balloon 360 degrees, while the precise clamping device firmly fixes the tail of the catheter in place. Balloons can also be indexed to the extent specified by the user.

Ultrasonic Coating Benefits for Balloon Catheters:

• Highly homogenous drug coatings onto balloon catheters
• Dramatic material savings compared to dip coating.
• More reliable, repeatable, controllable balloon catheter coatings than other techniques such as dip coating, air spray coating
• Capable of working on completed balloon catheter up to 2 meters in length
• Ability to selectively spray specific areas on balloon catheter rather than processing the entire balloon surfaces
• Catheter protected from damage by using soft material on catheter holders
• Durable coatings with no cracking or peeling ensure proper delivery of the drug at blockage site.
