1. A method of treating a stenosis in an intracranial vessel with an intracranial stent, the intracranial stent including a first end portion having a first bore, a second end portion having a second bore, and a central portion extending between the first and second end portions, the central portion being in communication with the first and second bores, the first end portion, the second end portion, and the central portion each forming a plurality of interstices formed by a plurality of struts and crowns, the struts extending continually from the first end portion to the second end portion via the crowns, the method comprising:
locating an expandable intracranial stent within the stenosis of the intracranial vessel, the central portion of the intracranial stent extending through a bore formed by the stenosis and with the first and second end portions adjacent to opposite ends of the stenosis; and expanding the intracranial stent so that the first and second end portions have diameters that are each larger than a diameter of the central portion, and so that the central portion is configured to apply a greater outward force as compared with the first and second end portions due to the interstices of the central portion being smaller than the interstices of the respective first and second end portions.
