Abstract:
1. A vascular stent, comprising: a proximal section having a first cross-sectional dimension and being configured to anchor in an afferent vessel of a bifurcation proximate to an aneurysm, the proximal section comprising a tubular shape that defines a proximal lumen; a distal section having a second cross-sectional dimension and being configured to be positioned in an efferent vessel of the bifurcation, the distal section comprising a tubular shape that defines a distal lumen; and a protruding section, between the proximal and distal sections, having a third cross-sectional dimension, the protruding section (i) being configured to abut an ostium of the aneurysm when the protruding section is positioned at the bifurcation, (ii) defining an intermediate lumen in fluid communication with the proximal and distal lumens, and (iii) having a strut pattern that is substantially the same as strut patterns of the proximal and distal sections; wherein the proximal, distal and protruding sections are expandable from a compressed configuration to an expanded configuration; wherein, in the compressed configuration, first cells of the proximal section and/or the distal section have a first compressed cell size greater than a second compressed cell size of second cells of the protruding section; wherein, in the expanded configuration, the first cells have a first expanded cell size substantially equal to a second expanded cell size of the second cells.
