    摘要: A method and device for coating a medical device, such as a stent, including forming coating droplets using a mesh nebulizer and transporting the coating droplets to the medical device, for example through a converging chamber. The coating droplets may be accelerated to a speed sufficient to break the coating droplets into smaller droplets upon impact with the medical device. The mesh nebulizer may have a convex inlet side and may form a converging plume of coating droplets. The mesh nebulizer may have one or more groups of pores, the pores within each group may be subject to similar amplitudes of vibration. The coating material may be heated or cooled prior to nebulizing. The chamber may include baffles configured to allow only a predetermined size range of coating particles to pass.
