摘要：
An intravascular filter assembly has an expanded state for capturing thrombi in a patient's blood vessel and a collapsed state for removal from the patient's blood vessel. The filter assembly includes a fixed hub defining a tubular portion, a plurality of struts extending from a first axial side of the tubular portion of the fixed hub, and an axially movable hub. The struts have an expanded configuration and a collapsed configuration. The axially movable hub has a first position radially surrounding at least an axial portion of the tubular portion and a second position axially spaced apart from the fixed hub along the struts. The struts are in the collapsed configuration when the movable hub is in the second position. A first coupling member extends from the first axial side from the movable hub； and a second coupling member extends from a second axial side opposite the first axial side.
