Figure 7:
Assessment of mechanical strength and extensibility of the patch at 24 months after implantation. (A) Testing unit and extent of expansion. Left: at rupture of neointima, right: at rupture of entire vessel. Double head arrows indicate the length of the regenerated wall. (B) Stress-extensibility curve [shaded area: the estimated physiological range (force approximately 0.1 N/mm2, expansion approximately 150%)]. (C) Change in length of the regenerated wall. In (B) and (C), the asterisk (*) indicates the point of neointimal rupture on the luminal side and the hashtag (#) indicates the point of complete rupture of the entire specimen.
