An intravascular filter assembly having an expanded state for capturing thrombi in a patient's blood vessel, a first a collapsed state for removal from the patient's blood vessel in a first direction and a second collapsed state for removal from the patient's blood vessel in a second direction, the filter assembly comprising: a fixed hub; a plurality of first struts extending from a first axial side of the fixed hub, the first struts having an expanded configuration when the filter is in the expanded state and a collapsed configuration when the filter is in the first collapsed state; a plurality of second struts extending from a second axial side of the fixed hub opposite the first axial side of the fixed hub, the second struts having an expanded configuration when the filter is in the expanded state and a collapsed configuration when the filter is in the second collapsed state; an axially movable hub having a first position radially surrounding at least a portion of the fixed hub, a second position axially spaced apart from the fixed hub along the first struts, and a third position axially spaced apart from the fixed hub along the second struts, the first struts being in the collapsed configuration when the movable hub is in the second position, and the second struts being in the collapsed configuration when the movable hub is in the third position; a first coupling member extending from a first axial side of the movable hub, the first axial side of the movable hub coinciding with the first axial side of the fixed hub; and a second coupling member extending from a second axial side of the movable hub opposite the first axial side of the movable hub; characterized in that at least one of the first and second coupling members forms a retainer limiting a distance of travel of the movable hub along the struts. a fixed hub; a plurality of first struts extending from a first axial side of the fixed hub, the first struts having an expanded configuration when the filter is in the expanded state and a collapsed configuration when the filter is in the first collapsed state; a plurality of second struts extending from a second axial side of the fixed hub opposite the first axial side of the fixed hub, the second struts having an expanded configuration when the filter is in the expanded state and a collapsed configuration when the filter is in the second collapsed state; an axially movable hub having a first position radially surrounding at least a portion of the fixed hub, a second position axially spaced apart from the fixed hub along the first struts, and a third position axially spaced apart from the fixed hub along the second struts, the first struts being in the collapsed configuration when the movable hub is in the second position, and the second struts being in the collapsed configuration when the movable hub is in the third position; a first coupling member extending from a first axial side of the movable hub, the first axial side of the movable hub coinciding with the first axial side of the fixed hub; and a second coupling member extending from a second axial side of the movable hub opposite the first axial side of the movable hub; characterized in that at least one of the first and second coupling members forms a retainer limiting a distance of travel of the movable hub along the struts.
