Abstract
An embolic protection device includes a basket defined by a section of a set of wires arranged as a plurality of struts. These struts are coupled together at the distal end of the basket in a manner to define an opening at the distal end through which a core wire can reciprocate. Another section of the wires spirals around the core wire to define a hollow channel in which the core wire can reciprocate. A filter bag is attached to the distal end of the core wire such that pulling a proximal end of the core wire relative to the spiraled section engages the filter bag with the distal end of the basket to expand the basket and filter bag for capturing clots, and pushing the core wire disengages the filter bag from the distal end of the basket to collapse the basket and filter bag.
