Numerical Analysis of a Novel External Support Device for Vein Bypass Grafts

This paper presents a numerical analysis of a novel external support device for coronary artery bypass graft (CABG). The analysis includes the fluid and the structural dynamics of vein grafts with and without an external support device (ESD). Six different vein grafts geometries were modeled under time-dependent physiological conditions. The hemodynamics and the stresses developed at the graft wall were analyzed on patient based geometries 12 months post-transplantation.
