120 kHz ultrasonic spraying technology for drug‑eluting balloon dilatation catheters is applied to deposit anti‑restenosis polymers and plasticizers onto implantable balloon catheters. It yields thinner, more uniform and better‑performing coatings. For certain balloon catheter models, an automatic inflation unit is required to pre‑inflate the balloon prior to the coating process.

This 120 kHz ultrasonic spraying system serves as the core component of the complete processing setup. Atherosclerosis has a high prevalence in China, particularly among the middle‑aged and elderly population, and coronary balloon angioplasty represents an effective therapeutic approach. Ultrasonic atomization technology has demonstrated proven performance for this specific application.

 

 

 

 

1. The ultra-thin and highly uniform film coated on cardiac and other interventional balloon catheters enables consistent and even drug delivery to lesion sites.

 

2. This spraying process significantly reduces material consumption compared with traditional immersion coating methods, delivering superior cost efficiency.

 

3. It delivers stable, reproducible and precisely adjustable coating results for balloon catheters, supporting standardized mass production.

 

4. The system supports ultrasonic atomization of commonly used medical formulations, including hydrophilic drug carriers and plasticizers, effectively improving the flexibility and ductility of functional coatings.

 

6. Precision targeted spraying is achievable on designated strip areas of the balloon surface, eliminating full-surface coating and meeting customized clinical application requirements.

 

 

 

1. Multiple‑pass spraying technology
Layered spraying: Instead of applying one‑time thick coatings, multiple thin layers are sprayed alternately. This enables precise incremental control over individual‑layer thickness, delivers improved coating uniformity, and mitigates coating‑related defects.

2. Spraying‑parameter optimization
Precise control over spraying speed and pressure: Coating thickness can be better regulated by tuning spraying speed, nozzle pressure and ultrasonic frequency. Lower spraying speed contributes to increased coating thickness, while higher nozzle pressure improves atomization performance.

3. Nozzle‑design enhancement
Customized nozzle design: Nozzles featuring different spray patterns (e.g., annular‑type or multi‑orifice nozzles) are developed to achieve superior coating distribution and thickness regulation.
