Abstract

An ultrasound apparatus and technique produces precise and uniform coatings on various substrates such as stents or other medical devices. The apparatus and technique increases adhesiveness of the surface of the stent or other medical device. In addition, the coating, drying, sterilization processes take place concurrently. The apparatuses generate and deliver targeted, gentle, and highly controllable dispensation of continuous liquid spray. The ultrasound coating apparatuses and techniques provide an instant on-off coating process with no atmospheric therpeutic agent contamination, no 'webbing,' no 'stringing' or other surface coating anomalies. Furthermore, the technology reduces wastage of expensive pharmaceuticals or other expensive coating materials.
