1. A method for delivering contrast media to an interventional site in a patient's aortic annulus, said method comprising:
providing a filter body formed at least partly from a porous mesh having (a) a wall defining an upstream chamber with an open upstream end and an open downstream end, and a port disposed inside the porous mesh, wherein the wall of the porous mesh is folded to form the port, (b) a radially constrained delivery configuration and a radially expanded deployed configuration, and (c) a radially collapsible and expandable support comprising a wire loop attached about a periphery of the open downstream end of the filter body, wherein the wire loop is attached to a deployment catheter;
advancing the filter body while radially constrained in a delivery sheath over the patient's aortic arch;
retracting the delivery sheath to radially expand the filter body so that the wall of the porous mesh covers the patient's aortic side vessels so that the open upstream end of the downstream chamber faces toward the heart and the open downstream end is held open by the wire loop;
advancing a distal end of a first working catheter through the filter body to lie proximate the patient's aortic annulus while the open downstream end of the filter body is held open by the wire loop;
introducing a contrast media to the interventional site through the first working catheter;
wherein the open upstream end of the filter body faces the patient's heart in order to direct blood flow and emboli into the open upstream end of the interior chamber of the filter body, wherein emboli are captured in the filter body, and wherein blood free from emboli flows through the cylindrical wall of the porous mesh into the aortic side vessels.
