Abstract
Described herein are implantable medical devices for delivering a therapeutic agent to the body tissue of a patient, and methods for making such medical devices. In particular, the implantable medical devices, such as intravascular stents, have a coating which includes at least one coating composition and has an exposed abluminal surface and an exposed luminal surface or exposed side surface.
Claims30
An implantable stent comprising:
- (a) a stent sidewall structure having an abluminal surface and a luminal surface opposite the abluminal surface;
- and
- (b) a coating comprising a coating composition disposed on at least a portion of the abluminal surface, wherein the coating has an exposed abluminal surface and an exposed luminal surface.
An implantable intravascular stent comprising:
- (a) a stent sidewall structure comprising a plurality of struts and a plurality of openings in the stent sidewall structure, wherein at least one strut comprises an abluminal surface and an luminal surface opposite the abluminal surface;
- and
- (b) a coating comprising a coating composition disposed directly on at least a portion of the abluminal surface of the strut, in which the coating composition comprises a biostable polymer and an anti-restenosis agent, and wherein the coating has an exposed abluminal surface and an exposed luminal surface.
An implantable stent comprising:
- (a) a stent sidewall structure having an abluminal surface and a luminal surface opposite the abluminal surface;
- and
- (b) a coating disposed on at least a portion of the abluminal surface, wherein the coating comprises:
- (i) a first coating composition disposed on at least a portion of the abluminal surface;
- and
- (ii) a second coating composition disposed on the first coating composition, wherein the coating has an exposed abluminal surface and an exposed luminal surface.
