Fig 1. Aneurysm model geometry. A, Sidewall aneurysm on a straight vessel (S) and aneurysms on curved vessels with different curvatures (C1–C3). Curvature is defined as C = 1/R, where R is the radius of curvature of the parent vessel. N indicates neck size; d, aneurysm diameter; , vessel diameter. B, Stent used in the flow experiment and mimicked in the CFD simulations (5 x 40 mm Wallstent). C, Computational mesh in a stented aneurysm model used for CFD analysis.
