Stent surface and geometry significantly affect vascular injury and neointimal hyperplasia.5 Two bare metal stent (BMS) where fabricated using the same metal, process, and net surface area, on in a slotted tube (upper left panel) and the other corrugated ring (lower left panel) configuration and implanted in rabbit femoral arteries. Histologic examination was performed on methylmethacyrlate-embedded specimens harvested two weeks following placement. A, B uncoated surface; C, D polymer coated surface. Internal elastic lamina (arrow), stent struts (black rectangles), and polymer material (white rim circumscribing stent strut in C & D). Adapted from Edelman and Rogers.5
