Abstract
A removable vascular filter device for blocking micro-and macro-emboli while allowing continued perfusion of blood, comprises a guidewire having distal and proximal portions, wherein there is a recess in the distal portion and a filter comprising a flexible filter membrane and a filter membrane support structure. The filter membrane has a fixed inner portion and a free outer portion, wherein the filter membrane fixed inner portion is movably attached toward the distal end of the guidewire recess and wherein the filter membrane free outer portion is positioned in the recess when the filter membrane is in a collapsed state. A deploying means causes the filter membrane proximal end portion to assume a position substantially normal to the longitudinal axis of the guidewire.
