Fig. 5. Compression/expansion loop diagrams, demonstrating the wide range of forces. The graphs start on the right as the diameter of the stent is compressed. More or less ideal curves are seen in (A). (B, C) Some stents are starting to exceed the load of the test system (arrowheads) and the erratic behavior of the thick polymer skeleton of the biodegradable stent is seen (arrows).
