    摘要: 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.

    摘要: A device for delivering an expandable member to a luminal structure in a patient is described. In some embodiments, the device has a carrier member, with a carrier lumen extending at least partially therethrough. The device can have an elongate member that extends through the carrier lumen across a first notch in the carrier member. The device can have an expandable member that expands within and engages the luminal structure, can be carried by the carrier member, and has a first portion that fits within the first notch. When the elongate member extends through the carrier lumen and across the first notch, the elongate member secures the first portion to the carrier member. The elongate member is configured to move axially through the carrier lumen such that the elongate member permits release of the first portion from the carrier member and expansion of at least part of the expandable member.

    摘要: Embodiments of an endovascular device and of methods for treating an aneurysm therewith are described. In certain embodiments, an endovascular device includes a distal assembly coupled to a flow reducing member. In some embodiments, the distal assembly is composed of multiple engagement members that, when deployed within an aneurysm, engage an inner surface of the aneurysm. In certain embodiments, the engagements members are substantially parallel to a central axis of the distal assembly in a first position and shift away from the central axis to a second position, and the distal ends of some engagement members are substantially curled when in the second position. In certain embodiments, the flow-reducing member reduces blood flow from a blood vessel into the aneurysm. In certain embodiments the flow reducing member includes a membrane, which can include a porous section.
