Abstract: There is provided a clot retrieval device (1), comprising: a rotator body (2) formed of a plurality of first longitudinal struts (20), wherein the first longitudinal struts (20) are fixed only at a proximal end (21) and a distal end (22), and the rotator body (2) is in an expanded configuration when it is in a free state, and can be in a collapsed configuration when it is inserted into a catheter; and a distal body (3) connected to the distal end (22) of the rotator body (2), the distal body (3) is in an expanded configuration when it is in a free state, and can be in a collapsed configuration when it is inserted into a catheter; wherein at least a portion of each of the first longitudinal struts (20) makes both radial expansion and circumferential rotation during a deployment phase of the rotator body (2) from the collapsed configuration to the expanded configuration.
