    摘要: 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.

    摘要: Systems, methods, and devices for the treatment of acute ischemic stroke that provide immediate blood flow restoration to a vessel occluded by a clot and, after reestablishing blood flow, address the clot itself. Immediate blood flow restoration advantageously can facilitate natural lysis of the clot and also can reduce or obviate the concern for distal embolization due to fragmentation of the clot. Several embodiments of the invention provide for progressive, or modular, treatment based upon the nature of the clot. For example, the progressive treatment can include immediate restoration of blood flow, in-situ clot management, and/or clot removal depending on the particular circumstances of the treatment. The in-situ clot management can include, for example, lysis, maceration, and/or removal.
