Abstract:
1. A clot removal device for restoring blood flow to a vessel occluded by an obstructive clot, the device having an expanded deployed configuration, and a retracted delivery configuration in which it may be advanced across said obstructive clot, the device comprising: an expandable clot retrieval portion configured for deployment on a distal side of the clot, the clot retrieval portion having a plurality of struts forming at least one hoop; an expandable portion configured for deployment on a proximal side of the clot, the expandable portion having a plurality of struts and a proximally tapering portion at a proximal end of the expandable portion, and the expandable portion being connected to the clot retrieval portion by a plurality of connecting elements; a clot receiving space between the clot retrieval portion and the expandable portion; and a longitudinally-extending member extending through the clot receiving space and coupled to the clot retrieval portion, wherein a central axis of the longitudinally-extending member is located along a central axis of both the clot retrieval portion and the expandable portion, wherein the clot removal device includes a clot retrieval configuration during withdrawal of the expandable clot retrieval portion into a catheter that is smaller than the expanded deployed configuration of the expanded clot removal device, the clot retrieval configuration maintaining the clot receiving space between the clot retrieval portion and the expandable portion.
