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, the first frame configured to be inverted such that the distal portion moves within and toward the middle portion for removing the first frame from within the lumen; 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 at least one of emboli and fluid flowing through the lumen.

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.

18. 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; 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; and removing the first frame from within the lumen by inverting the first frame such that the distal portion moves within and toward the middle portion. - View Dependent Claims (19)

20. A method for reducing or stopping flow through a tubular structure of a patient, the method comprising:
-
positioning an outer catheter within a lumen of the tubular structure at a first deployment site, wherein an inner catheter is disposed within the outer catheter, wherein a first elongate member is positioned between the inner catheter and the outer catheter, 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, partially deploying the first frame from the outer catheter by shifting the inner catheter distally relative to the outer catheter until a portion of the first frame extends beyond a distal opening of the outer catheter into the first deployment site; retracting the first frame into the outer catheter by shifting the inner catheter proximally relative to the outer catheter until the portion of the first frame is retracted proximally into the outer catheter; positioning the outer catheter within the lumen at a second deployment site for deploying the first frame at the second deployment site; deploying the first frame from the outer catheter by shifting the inner catheter distally relative to the outer catheter until the first frame extends beyond the distal opening of the outer catheter into the second deployment site; 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.
