Development and mechanical evaluation of nonlinear anisotropic aortic models for in vitro experimentation

In the past decades multiple techniques have focused in the characterization of the vasculature elasticity in a clinical setting. In their development in vitro testing and validation is mandatory. Unfortunately, this is done on arterial phantoms that are isotropic, linearly elastic, and that do not match the real mechanical and morphological properties of the vessels. In this work, we developed a series of phantoms made from clinical images and compared them to ex vivo pig aortas.
