Abstract
Components and corresponding systems are described for providing removal of a clot or fragment thereof to address an acute ischemic stroke condition. In particular, a filter design is presented that provides metal elements below a bundle of polymer fibers to provide more mechanical strength while cushioning the vessel wall from direct contact with the metal elements. Designs of stent retrievers are presented with polymer covers or mounted on the exterior of a microcatheter. Corresponding systems are described that can use various combinations of the components, generally in combination with an aspiration catheter. Corresponding procedures are described that can effectively use the various devices and systems.
