1. An occlusive device for treating an aneurysm, wherein a neck of the aneurysm opens to a blood vessel, the device comprising:

  • a first elongated mesh having a low-profile state for intravascular delivery to the aneurysm and an expanded state in which the first elongated mesh is curved about a first axis to form a first band, the first elongated mesh having a first length and a generally constant width along the entire first length; and

    a second elongated mesh having a low-profile state for intravascular delivery to the aneurysm and an expanded state in which the second elongated mesh is curved about a second axis different than the first axis to form a second band, the second elongated mesh having a second length and a generally constant width along the entire second length, wherein a distal end of the second elongated mesh is coupled to a proximal end of the first elongated mesh,wherein the second band is positioned radially inward of the first band such that the device includes first and second overlap regions in which the first band overlaps the second band, and wherein the first and second overlap regions are spaced apart from one another along a circumference of the first band.
