Enterprise Stent: constant 8-mm opening, increasing bend. MIPs, using section thickness of 5.0 mm (left column) and 1.0 mm (right column), bending with 90°, 60°, and 30° angles, over a 8-mm hole simulated “aneurysm neck” (dotted blue ellipse). It is evident that starting from a 90° bend, the Enterprise stent shows initially a minor flattening at its midsection that increases with 60° and becomes a true kinking at 30°. It also documents that the stent tends not to completely collapse, even though the midsection of the stent significantly changes its shape from round to oval and the diameter becomes relatively small (miniatures).
