A braided stent comprises a filament having at least one circular zone and at least two non-circular zones. Embodiments of the braided stent have a proximal segment, a middle segment, and a distal segment, wherein a porosity of the middle segment is lower than, a respective porosity of the proximal and distal segments. In one embodiment, a radial pressure of the middle segment is separately controlled to be different from, e.g., less than, a radial pressure of the distal segment. In another embodiment, a stiffness of the middle segment is separately controlled to be different from, e.g., less than, a stiffness of the distal segment.
