Claim:
An embolic protection device for use in a vessel, the embolic protection device comprising: a basket having a first end and a second end, a longitudinal axis of the basket extending between the first end and second end, a middle portion of the basket being located between the first end and second end, the basket including a plurality of struts, the plurality of struts extending radially from the first end to the middle portion; the struts extending a distance that is at least substantially perpendicular to the longitudinal axis in order to form a circle substantially along the circumference of the middle portion; the plurality of struts extending from the circumference of the middle portion to the second end toward the longitudinal axis, the plurality of struts comprising four struts, wherein the basket is movable between an expanded state and a collapsed state; a filter portion attached to the plurality of struts along the circumference of the middle portion and extending between the middle portion and the second end of the basket, wherein the filter portion is attached along the plurality of struts between the middle portion and the second end, the filter portion having a distally facing concave shape when the basket is in the expanded state; and a core wire extending from the second end and between the first end and the second end, wherein the plurality of struts and the filter portion are attached to each other and to the core wire at the second end; wherein the core wire is slidable distally relative to the plurality of struts to force the basket into the collapsed state; wherein in the expanded state the plurality of struts provide a radial force to support the filter portion.
