1. A method for embolizing a blood vessel having an endoluminal wall defining a vascular lumen, the method comprising:

  • advancing, via a pusher, an occlusion device to a target site in the vascular lumen of the blood vessel while the occlusion device is in a compressed state;

    deploying the occlusion device at the target site in the blood vessel, wherein the occlusion device includes a mesh structure defining a longitudinal axis, wherein deploying the occlusion device includes radially expanding the occlusion device from the compressed state to an expanded state, and wherein, in the expanded state—

    the occlusion device includes a plurality of radially extending regions,individual ones of the radially extending regions include an apex that contacts the endoluminal wall of the blood vessel,each of the apices has a thickness along the longitudinal axis of the occlusion device, andthe combined thicknesses of the apices is less than about 50% of a total length of the mesh structure along the longitudinal axis;

    detaching the occlusion device from the pusher; and

    maintaining the occlusion device in the expanded state at the target site in the blood vessel at least until the vascular lumen at the vascular site is embolized to occlude blood flow through the vascular lumen.
