A clot retrieval device for removing thrombi or other emboli from a body lumen is disclosed. The clot retrieval device includes an elongate shaft portion, a self-expanding snare disposed at a distal end of the shaft portion and a flexible bag portion attached to the self-expanding snare. The snare may be a loop or circlet formed in a distal end of the elongate shaft portion or may be a separate component attached thereto. An opening of the bag portion for receiving the thrombi or emboli there through faces proximally when the snare is fully deployed. The bag portion is made of a flexible, non-porous material, such as a balloon-type or elastomeric material, that is foldable or otherwise collapsible to achieve a low-profile while the clot retrieval device is being tracked to the treatment site through the body lumen.
