Abstract:
1. A method of filtering embolic debris from a blood vessel, comprising the steps of: providing a elongate shaft having a filter frame coupled thereto, the filter frame having a filter material permeable to blood coupled thereto, the shaft having an expansion member disposed therein; advancing the shaft to an area proximate a lesion within a blood vessel of a patient, the blood vessel having a lumen therethrough; actuating the expansion member so as to shift the filter frame from a generally collapsed configuration to a generally expanded configuration such that the filter material conforms to the blood vessel lumen, wherein expanded the filter frame is generally cylindrical in shape and has a diameter and a length, the diameter being larger than the length; performing an intravascular procedure that generates embolic debris; capturing embolic debris with the filter material; and aspirating the filter material.
