Study of conformability of the new leo plus stent to a curved vascular model using flat-panel detector computed tomography (DynaCT).

Objective: In a previous study, we assessed the conformability limitations of self-expandable stents to a curved vascular model. The LEO stent (Balt Extrusion, Montmorency, France), one of the current self-expandable models available for intracranial aneurysm stenting, displayed 2 adverse mechanics: flattening of the stent midsection and inward crimping of the proximal and distal ends. We present a follow-up study in which we evaluate the conformability to curved vessels of a second-generation stent, LEO PLUS.
