Abstract
An endovascular stent-graft is provided that includes a structural member, which includes structural stent elements, at least a portion of which define a stent body when the stent-graft assumes a radially-expanded state; and a fluid flow guide. When the stent-graft assumes the radially-expanded state, (a) a first subset of the structural stent elements are configured to cause the stent body and the fluid flow guide to define a bulge that extends radially outward and has a greatest cross-sectional area that is equal to at least 120% of a cross-sectional area of a narrowest portion of the stent-graft rostral to the bulge, and (b) a second subset of the structural stent elements are not configured to cause the fluid flow guide to define the bulge. The structural stent elements of the first subset at least partially overlap the structural stent elements of the second subset lengthwise along the stent body.
