Devices and methods for centering an intravascular filter within a blood vessel are disclosed. A filter system in accordance with an exemplary embodiment of the present invention may include an intravascular filter, a filter sheath adapted to contain the intravascular filter, and a centering member adapted to assume a preset shape when deployed within a blood vessel. The centering member may comprise an elongated wire having a hoop section adapted to radially expand against the inner wall of the blood vessel when deployed. In some embodiments, multiple centering members can be employed to facilitate centering of both the intravascular filter and the filter sheath within the blood vessel, if desired.
