Reducing flow through a tubular structure
First Claim
1. An apparatus for reducing or stopping flow through a tubular structure of a patient, the apparatus comprising:
- a 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; and
a first flow reducing member coupled to the first frame such that when the first frame is positioned within the lumen, the first flow reducing member substantially reduces or totally obstructs flow of fluid flowing through the lumen, 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 single flap in the interior of the first frame, the single 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.

Abstract
In some embodiments, an apparatus, for reducing or stopping flow through a tubular structure of a patient, includes an elongate member arranged to form a frame having a distal and proximal opening and configured to be positioned within a lumen of the tubular structure. The frame includes a proximal, distal, and middle portion. The distal portion is tapered such that an outer cross sectional dimension (OCSD) of the distal opening is less than an OCSD of the middle portion. The frame is configured to be inverted such that the distal portion moves within and toward the middle portion for removing the frame from within the lumen. The apparatus also comprises a flow reducing member coupled to the frame such that when the frame is positioned within the lumen, the flow reducing member substantially reduces or totally obstructs flow of at least one of emboli and fluid flowing through the lumen.
