Ultrasonic Spray Nozzles For Stents

Coating arterial stents is a challenging spray application. The fact that these devices are used in lifethreatening situations places stringent demands on the manufacturing processes used to produce them.

Ultrasonic spray nozzles are ideally suited to the application since they are capable of producing very low flow rates, precisely shaped spray patterns, lowvelocity delivery, and relatively small drops. The techniques used in coating may vary, as may the drug/polymer system. These variances make it important to optimize the entire system for each specific circumstance.
