Abstract
Methods of coating an implantable device and a system for performing such methods are disclosed. An embodiment of the method includes applying a coating substance to the surface of an implantable device, and rotating the implantable device in a centrifuge. The method can uniformly coat the implantable device with the coating substance and to remove unwanted accumulations of coating substance entrained between struts or crevices in the implantable device body. This system is applicable to methods for coating intraluminal stents, synthetic grafts, and stent coverings with therapeutic compositions comprising therapeutic agents mixed with a polymeric matrix and a solvent.
