As in previous study [( 47 )], the constitutive properties of the tracheal stenotic tissue was modeled as hyperelastic material, in which we assumed an increased stiffness of about two times with respect to the muscular membrane. Finally, the silicon stent was modeled as an isotropic elastic material. In Table...
