An intracranial stent includes 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, and a proximal transition portion extending from the proximal end portion to the central portion, the proximal transition portion having a substantially frustoconical shape such that the proximal transition portion transitions from the first diameter to the third diameter. The intracranial stent also includes a distal transition portion extending from the distal end portion to the central portion, the distal transition portion having a substantially frustoconical shape.
