1. An embolic protection device, said device comprising:
a filter body comprising a single wall tubular porous mesh having an open upstream end, an open downstream end, and a port disposed on an upstream side of the open downstream end, wherein a portion of said single-wall tubular porous mesh is folded to form said port comprising an expandable opening configured to conform to at least one working catheter passing therethrough;
a radially collapsible and expandable support comprising a wire loop attached about a periphery of the downstream end of the filter body;
a catheter body having a distal end coupled to the radially collapsible and expandable support; and
a delivery sheath having a lumen configured to receive and radially constrain the filter body;
wherein the catheter body may be distally advanced relative to the delivery sheath to release the filter body from constraint and to allow the filter body to radially expand and wherein the catheter body may be proximally retracted relative to the delivery sheath to reposition the support and filter body back into the lumen of the delivery sheath such that the support radially collapses the downstream end of the filter body prior to the filter body being repositioned within the lumen.
