Title:	Plasticizers for coating compositions
Abstract:	A biocompatible plasticizer useful for forming a coating composition with a biocompatible polymer is provided. The coating composition may also include a biobeneficial polymer and/or a bioactive agent. The coating composition can form a coating on an implantable device. The implantable device can be used to treat or prevent a disorder such as atherosclerosis, thrombosis, restenosis, hemorrhage, vascular dissection or perforation, vascular aneurysm, vulnerable plaque, chronic total occlusion, claudication, anastomotic proliferation for vein and artificial grafts, bile duct obstruction, ureter obstruction, tumor obstruction, or combinations thereof.
