<p>A stent with a plurality of relief cuts (131-136,141-148)formed in the interconnected struts (111-116) is provided with therapeutic material (150). Relief cuts are formed to extend through the truts and be filled with plugs of therapeutic material, where one or both exterior surfaces of the stent may be coveredwith a medicine or other type of coating. Multiple coatings may also be applied to the stent.coatings may be applied to some regions of the stent and not be present on other regions. Relief cuts are placed at flexion points,such that the struts have increased widths and reduced thicknesses while lattice support relief cuts between flexion points increase adhesion of therapeutic coating on the stent.</p> |
