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.

The present invention provides a wire guide () suitable for use in a body vessel, such as a peripheral vessel. The wire guide comprises a core member () and a first coiled member (), each having proximal and distal ends. In one embodiment, the core member comprises at least one recessed portion (), wherein the proximal end of the first coiled member is seated at least partially within the recessed portion to form a substantially flush exterior surface with the core member. The wire guide further preferably comprises a second coiled member () having proximal and distal ends, wherein the second coiled member is disposed distal to the first coiled member. The distal end of the first coiled member may be partially intertwined with the proximal end of. the second coiled member. A shaping ribbon () may be disposed substantially beneath the second coiled member to achieve a desired curvature at the distal tip of the wire guide.
