A clot retrieval device (1) has a clot engaging portion configured at the distal end of an elongate shaft (6) having an outer expandable member (2) comprising multiple expandable segments (26), and an inner expandable member (3) to facilitate restoration of blood flow through clot immediately after the clot retrieval device (1) is deployed at an obstructive site. The outer member (2) and inner expandable (member (3) comprises a collapsed configuration for delivery and an expanded configuration for clot retrieval, flow restoration and fragmentation protection. Proximal radiopaque markers (82) are positioned at the distal end of struts (20) of the outer member (2) just proximal to two proximal crowns (81). This position is advantageous because it denotes the start of the fully expanded diameter of the device, which is the portion of the device that is most desirable to deploy under the clot for optimal grip of the clot.
