1. An intracranial stent, comprising:
a proximal end portion having a first diameter when the intracranial stent is in an expanded state;
a distal end portion having a second diameter when the intracranial stent is in the expanded state;
a central portion located between the proximal end portion and the distal end portion, the central portion having a third diameter when the intracranial stent is in the expanded state, the third diameter being less than the first diameter and less than the second diameter, wherein the third diameter of the central portion is 25% to 70% of the first diameter of the proximal end portion or 25% to 70% of the second diameter of the distal end portion; and
patterns of interstices being formed in the proximal end portion, in the distal end portion, and in the central portion, the interstices in the central portion having areas that are smaller than respective areas of the interstices in the proximal end portion and in the distal end portion when the intracranial stent is in the expanded state,
the intracranial stent having an unexpanded state in which diameters of the proximal end portion, the distal end portion, and the central portion are smaller than the first diameter, the second diameter, and the third diameter, respectively.
