Abstract
A coating device for coating a medical device with a drug-eluting material uses an in-process drying station between coats to improve a drug release profile. The drying station includes a heat nozzle configured for applying a uniform drying gas. A coating process using the dryer includes a closed-loop control for the gas between drying steps and an improved nozzle for producing more consistent spray patterns.
