Claim:
1. A material delivery device, comprising: an expandable support member having a lumen and an outflow end, the support member comprising a pair of wires collectively forming a series of loops being configured to expand from a collapsed configuration to an expanded configuration for placement in a body lumen; a cover component, extending along the support member, defining an aperture at a distalmost loop at the outflow end of the support member; and a valve component comprising nonmovable and movable components, the nonmovable component being coupled to the distalmost loop, the movable component being coupled to the nonmovable component via a plurality of fasteners about an entire periphery thereof to permit the movable component to move between (i) an open position, wherein the movable component is evenly spaced apart distally from a distal end of the support member to permit outflow of a material through the aperture via a gap extending about the entire periphery of the movable component, and (ii) a closed position, wherein the movable component abuts the nonmovable component to close the gap and restrict backflow of the material into the aperture.
