Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A catheter-based blood-flow restoration system configured to restore blood flow in an occluded blood vessel of a subject's neurovasculature, comprising: a microcatheter having a lumen, a blood flow restoration device configured to be disposed within the lumen of the microcatheter, wherein the blood flow restoration device comprises a self-expandable capturing member coupled to a distal end of an elongate delivery member, the elongate delivery member comp…
