Table 3.

Parametric studies suggested that particular combinations of ω* and ε could reduce the peaks in linearized stiffness throughout TEVG evolution and thus better approach the compliance of the native IVC by 2 years. Note that the range of preferred combinations yielded a normalized pore size r* from 2.30 to 3.95, with optimal suggested values between 3.07 and 3.56 for ε = 75, 80, 85% (shaded in light grey). ε = 60 and 95% (not shown) resulted in large peaks in linearized stiffness regardless of the value of ω* given the large discrepancies between polymer modulus and ECM material properties.
