Claims25
A method of forming a coating on a stent, comprising:
- (a) positioning a nozzle in close proximity to or in contact with a stent, the stent having a scaffolding network including gaped regions;
- and
- (b) moving the nozzle from a first position to a second position while maintaining the nozzle in close proximity to or in contact with the scaffolding network to deposit a coating material on at least a portion of the scaffolding network, wherein the nozzle is moved along the pattern of the scaffolding network between the first position and the second position to avoid any significant application of the coating material in the gaped regions.
