Introduction to Medical Device Coatings

FUNSONIC offers a variety of ultrasonic spraying methods for medical device coatings, such as drug-eluting stents, drug-eluting balloons, guide wires, hypotubes, catheters, mandrels, etc. Ultrasonic spraying technology is a widely accepted method for coating small three-dimensional object scaffolds and other structures with complex structures. Due to the ultra-low flow capacity and low-speed soft spray characteristics, ultrasound is an ideal choice for spraying expensive materials (such as drugs) in polymer solvent solutions (such as sirolimus (rapamycin) and paclitaxel). In addition, ultrasonic spraying can replace traditional immersion coating methods for components such as guide wires, catheters, and hypotubes, thereby reducing waste, improving concentricity and longitudinal uniformity.

Advantages of ultrasonic spraying technology:

1. Ultrasonic waves can minimize product or material clumping to the greatest extent possible.
2. During the application, shearing, and separation of suspended materials, ultrasonic technology will not damage the chemical composition of the solvent due to excessive exposure to the atmosphere.
3. Ultrasonic vibration effectively prevents nozzle blockage.
4. Achieve maximum uniformity in film thickness and density.
5. Low speed spraying can reduce overspray.
6. The spray can be easily formed and guided to the target area only.
7. Made of medical grade materials, designed to be sturdy, wear-resistant, and corrosion-resistant.
