Figure 3 Photomicrographs show rabbit iliac arteries stained with Verhoeff’s tissue elastin stain six months after balloon denudation and stent implantation. (A) After uncoated stent implantation, a thick neointima separates the lumen from the internal elastic lamina. (B) After implantation of a poly(lactide-co--caprolactone)-coated paclitaxel-releasing stent, no neointima is present upon the internal elastic lamina with only a thin cap covering the stent struts.
