MEDICAL APPLICATION
Ultrasonic Spray Coating for Drug-Eluting Stents and Balloon Catheters
Precise drug-polymer coatings on stents and balloon catheters, supporting complex drug release profiles with minimal material waste.
The Challenge
Drug-eluting stents require micron-thick, uniform coatings of expensive drug/polymer matrices on tiny cylindrical mesh-like structures. Traditional coating methods waste significant amounts of high-value APIs, produce inconsistent film thickness on complex geometries, and struggle to achieve the multi-layer architectures needed for controlled drug release profiles.
Our Solution
With hundreds of hours of hands-on stent coating experience working with top-tier companies like Boston Scientific, Medtronic, J&J, and Surmodics, MicroSpray provides proven ultrasonic atomization for drug-eluting stents. Consistent droplet size and spatial control ensure homogeneous film formation on cylindrical stent structures, enabling sequential layers of primers, APIs, and topcoats for complex drug release profiles with over 90% transfer efficiency.
