1. A method for reducing or stopping flow through a tubular structure of a patient, the method comprising:

  • positioning a first elongate member within a lumen of the tubular structure, the first elongate member arranged to form a first frame having a distal opening and a proximal opening, the first frame having a proximal portion, a distal portion, and a middle portion therebetween, the distal portion tapered such that an outer cross-sectional dimension of the distal opening is less than an outer cross-sectional dimension of the middle portion; and

    substantially reducing or totally obstructing, with a first flow reducing member coupled to the first frame, flow of at least one of emboli and fluid flowing through the lumen, the first flow reducing member comprising a one-way valve that moves in response to fluid flow to substantially prevent distal flow through the distal opening and to allow proximal flow through the distal opening.
