Abstract
Devices for restoring blood flow to facilitate lysis of clots and/or enable capture of clots are disclosed. The devices can be configured to be disposed within a lumen of a microcatheter that is inserted within neurovasculature above a carotid siphon to a location of a clot. The devices can include an elongate pusher member and a self-expandable capturing member coupled to a distal end of the elongate pusher member. The capturing member can comprise a generally cylindrical body having an cell structure that is configured to compress the clot against an inner wall of the neurovasculature and capture the clot at least partially on a surface of the generally cylindrical body upon deployment of the capturing member from the microcatheter, thereby restoring blood flow to the neurovasculature downstream of the clot.
