Anti-restenosis Drug Coating Technique for Balloon Catheters
It is widely recognized that drug-eluting balloon catheter is a potential implantable medical device instead of drug-eluting stent. As a leader in the ultrasonic atomization industry, Siansonic has more than 10 years experience in thin film coatings deposition on balloon catheters by using ultrasonic spray coating technology. Compared to conventional dip coating and air spray coating, ultrasonic coating technology can achieve higher uniformity, greater repeatability.

Siansonic balloon catheter ultrasonic spray coater UC510 is specifically designed for balloon catheters up to 300mm in length. The special fixture in the system can hold one catheter up to 2 meters in length. The soft and precise spray atomized by Focusmist ultrasonic spray nozzles can deposit the drug solutions on specific area of the balloon. The special fixture in the system can be removed or replaced for coating other medical instruments such as peripheral stents. UC510 ultrasonic coating system which is able to equip with multi-nozzle units and patented multi-balloon catheters fixture can coat multi balloons simultaneously and significantly increase the rate of coating process.
The specific coating laboratory in our site provide the process testing services for customers at any time, which can help customers to improve and establish process criteria. Our engineers and technicians in laboratory have plentiful experience in coating different types of balloon catheters.
Siansonic Ultrasonic Coating Benefits for Balloon Catheters:
Highly uniform thin film coatings onto cardiac or other balloon catheters.
Highly Reliable, repeatable, controllable balloon catheter coatings.
Significant material savings compared to dip coating.
Capable of atomizing common combinations of chemistries, including hydrophilic carriers and plasticizers for added coating flexibility.
Durable coatings with no cracking or peeling ensure proper delivery of the drug at blockage site.
Capable of depositing specific areas on balloon surfaces (stripes) rather than coating the whole balloon.
No damage to the catheter assembly due to medical grade gaskets used on the catheter holder.
