Method for spray coating a medical device using a micronozzle

摘要

The present invention provides for a method for spray application of a coating material onto a medical device by spraying coating material from a micronozzle fabricated from a plurality of sheets that are etched with holes or openings. The openings are aligned to form fluid channels and the sheets are fused together in a planar fashion to define a micronozzle. In another embodiment, the invention provides for a method for spray application of a coating material onto a medical device using micronozzles fabricated in batches by a simplified manufacturing process. In other embodiments, the invention provides for a method for spray application of a coating material onto a medical device by spraying coating material from a micronozzle that includes a swirl or gas-assist atomizer.
