Abstract
A filter comprising a porous material is arranged in a generally conical shape having an expandable base and a vertex. An elongate member having a proximal end and a distal end is attached to the expandable base of the porous material at a first circumferential location of the expandable base and extends perpendicularly from a central axis of the filter. An aspiration tube, for removing embolic material under vacuum, communicates with an area at the first circumferential location of the expandable base. Methods of using the filter and occluding devices for protecting a patient from embolization during cardiovascular procedures are described.
