Reducing flow through a tubular structure |
摘要 |
A method for reducing or stopping flow through a tubular structure of a patient can include positioning an elongate member within a lumen of the tubular structure. The elongate member can be arranged to form a frame having a distal opening and a proximal opening. The elongate member can substantially reduce or totally obstruct, with a flow reducing member coupled to the frame, flow of at least one of emboli and fluid flowing through the lumen. The flow reducing member can comprise 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. |

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 configured to be positioned within a lumen of the tubular structure, 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, the first frame coupled to a first flow reducing member, the first flow reducing member being disposed over an exterior of the first frame and over the distal portion with at least a portion of the first flow reducing member extending from the exterior of the first frame into an interior of the first frame through the distal opening to form a flap in the interior of the first frame, the flap configured to operate as 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; and substantially reducing or totally obstructing, with the first flow reducing member, flow of at least one of emboli and fluid flowing through the lumen. |
