Abstract

In some embodiments, a medical device for recanalizing a vessel having a blockage and restoring blood flow through an obstructed blood vessel includes an expandable member coupled to a core wire and a hypotube that are movable relative to each other to manipulate the expandable member between various configurations. The expandable member having a capture structure in an expanded configuration. The expandable member can include multiple interstices formed by woven mesh filaments or braided strands through which the material blocking the vessel can pass. The capture structure can include a shape on its external surface that facilitates dislodgement and capture of the material within capture spaces created by the expandable member. Some embodiments include a capture sack or cap for capturing material and preventing material from migrating down stream of the blockage. Superoxygenated blood can be infused distal to the blockage to minimize loss of function during an ischemic event.

First claim

What is claimed is:

1. An apparatus, comprising:
an elongate member; and
a self-expanding braided expandable member defining a plurality of openings and coupled to the elongate member, the self-expanding braided expandable member configured to move from a collapsed configuration to an expanded configuration when unconstrained;
the self-expanding braided expandable member configured to be inserted into a blood vessel in the collapsed configuration and move to the expanded confi…
