Claim:
1. A clot retrieval device for removing clot from a blood vessel, the device having a collapsed delivery configuration and an expanded deployed configuration and comprising: a shaft extending between a proximal end and a distal end; a self-expandable outer body eccentrically coupled to the shaft, the expandable outer body comprising a plurality of longitudinally spaced clot scaffolding segments separated by voids forming a plurality of clot inlet mouths between the adjacent clot scaffolding segments, wherein each clot scaffolding segment includes a plurality of closed cells, wherein at least one closed cell of each of the plurality of the clot scaffolding segments terminates in a distal apex free from connection to an adjacent closed cell; and an inner expandable body including a plurality of struts, the outer expandable body at least partially overlying the inner expandable body and being expandable to a radial extent which is greater than the radial extent of the inner expandable body in the deployed configuration to provide a clot reception space radially between the inner expandable body and the outer expandable body.
