A single-wire expandable cage for an embolic filtering device includes a single cage wire coupled to an elongated member, such as a guide wire, and adapted to expand from an unexpanded position to an expanded position in a patient's body vessel. The wire includes a first end and a second end which are coupled to the guide wire. A filter element is attached to the single-wire cage. The single-wire cage may be rotatably mounted to the guide wire or may be slidably disposed on the guide wire to allow the composite cage and filter element to be slid over the guide wire in an over-the-wire fashion once the guide wire is delivered to the target location in the patient's vasculature. One embodiment of the single-wire cage utilizes an offset arrangement in which the guide wire remains extended along the wall of the body vessel once the single-wire cage is deployed. Another embodiment of the device centers the guide wire within the body vessel.
