Abstract
Methods of implanting a device in the lumen of a blood vessel are described. The method includes providing a microcatheter and a device. 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 microcatheter is advanced to a region of interest within the blood vessel. The support structure is advanced through the lumen of and out the distal end of the microcatheter where it expands to the expanded state.
