Abstract
Systems and methods for coating medical devices are provided that allow for relatively precise control over the deposition area and coating uniformity with improved efficiency. A microdrop source is used to provide a flow of coating microdrops. A charging electrode disposed near the outlet of the coating source gives each microdrop an electrostatic charge. As the microdrop travels toward the medical device to be coated, a control electrode alters the trajectory of the microdrop. The invention can include a scanner to scan or image the medical device as the coating is applied and a control system to adjust parameters of the deposition process based on information provided by the scanner.
