Devices for treatment of a patients vasculature are described. The device includes a first hub, a second hub, a support structure including a plurality of struts disposed between the first hub and the second hub, and a layer of material disposed over the plurality of struts. The support structure has a low profile, radially constrained state with an elongated tubular configuration suitable for delivery from a microcatheter. The support structure also has an expanded state, a smooth outer surface, and has an axially shortened configuration relative to the radially constrained state. The layer of material may be made from acrylic, silk, silicone, polyvinyl alcohol, polypropylene, polyester, PolyEtherEther Ketone (PEEK), polytetrafluoroethylene (PTFE), polycarbonate urethane (PCU), or polyurethane (PU). The support structure may be formed from a slotted tubular member.
