Vena cava filter with dual retrieval

摘要

An intravascular filter assembly (20) 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 (10) defining a tubular portion, a plurality of struts (12) extending from a first axial side of the tubular portion of the fixed hub (10), and an axially movable hub (24). The struts (12) have an expanded configuration and a collapsed configuration. The axially movable hub (24) 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 (10) along the struts. The struts (12) are in the collapsed configuration when the movable hub is in the second position. A first coupling member (26) extends from the first axial side from the movable hub (24); and a second coupling member (28) extends from a second axial side opposite the first axial side.
