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, the device comprising:

  • an expandable clot retrieval portion having a plurality of struts forming a clot inlet mouth having a pair of opposed bifurcations at a periphery of a proximal end of the clot retrieval portion, wherein the clot inlet mouth includes a distal-most apex at a midpoint between the pair of opposed bifurcations;

    an expandable portion located proximal the clot retrieval portion, the expandable portion having a plurality of struts and a proximally tapering portion at a proximal end of the expandable portion;

    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 two distal struts extend distally from each bifurcation of the pair of opposed bifurcations.
