Bentchtop balloon catheter coating system is a compressed ultrasonic coating system specially used for depoisting of drug layer on balloon catheters or peripheral stents. Compared with the standard balloon catheter coating system, the size is smaller and can be placed on the bench. It is suitable for customers with limited space or initial research and development.It is equipped with Siansonic FocusMist or NanoMist ultrasonic nozzle to deposit drug coating onto the balloon catheter or stent surface through ultrasonic atomization technology. It can precisely control the balloon catheter coating process, and the coating layer is uniform without adhesion, pinholes, orange peel and other defects. Equipped with unique balloon catheter and peripheral stent holders, it can be used for various drug eluted balloon catheters such as coronary balloon, peripheral balloon and also peripheral stents. 

Siansonic FocusMist ultrasonic nozzle which has small spray width and low flow rate is very suitable for coating process on balloon catheter. For the drug eluted coronary balloon, peripheral balloon and other balloons, the drug such as paclitaxel is usually dissolved in organic solvent or water based solvent to prepare a drug solution. After the solution atomized by the ultrasonic nozzle, it uniformly deposits onto the balloon surface to form a uniform drug coating without defects such as adhesion, pinholes and bubbles. The balloon catheter coating system has unique balloon catheter holders which can realize rapid loading and unloading of balloon catheters, and can support the balloon catheter with up to 2 meters in length. At the same time, it can also be equipped with optional peripheral stent holder to deal with peripheral stents with different specifications.

Siansonic also provides patented balloon catheter coating system for multiple balloon catheters or peripheral stents. The patented holder system can realize the rapid loading and unloading of multiple balloon catheters, greatly improving the production efficiency.

Furthermore, the specific balloon catheter 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 and stents.
