Ultrasonic Atomizer UAM1000 For Stent And Balloon Drug Coating

The UAM1000 ultrasonic atomizer is designed for precise drug coating on coronary stents and PTCA dilation balloons. It utilizes low-temperature ultrasonic atomization to preserve biological activity of drugs, achieving uniform micron-level coatings with high raw material utilization. This system supports customizable dual-mode spraying for stents and balloons, making it a versatile solution for medical device manufacturers.

Key Selling Points

• Micron-level precision: Droplet size from 18-200 μm (frequency dependent) enables ultra-thin coatings from 20 nm to 100 μm, ensuring uniform drug distribution on complex stent and balloon geometries.
• Low-temperature atomization: Non-thermal process prevents drug degeneration, compatible with various medical solvents and polymer liquids, maintaining biological activity.
• High material utilization: Ultrasonic vibration ensures efficient transfer, reducing liquid medicine usage by up to 37% in mass production, lowering consumable costs.
• Non-clogging nozzle: Open structure and anti-clog design minimize maintenance downtime, supporting continuous production.
• Dual-mode customization: Support stent mode with 360° rotating tool and balloon mode with curved-surface adaptation, achieving complete coverage without dead angles.
