Evaluation of Implanted Stent Occlusion Status Based on Neointimal Tissue Bioimpedance Simulations

Figure 1

Restenosis in an implanted stent after (a, b) 7 years and (c, d) 4 years, from [7]. Note that (b) and (d) are zoomed images from (a) and (c), respectively. The asterisks inside the holes in (b) and (d) represent the stent metal struts. The yellow arrows indicate the thinnest part of a fibre layer. NC: necrotic cores.
