Abstract
A method for embolic protection during treatment of a stenotic lesion in a body vessel is provided. The method comprises disposing an embolic protection device in an undeployed state in the body vessel. The device comprises a basket with a set of struts extending from a distal end to a proximal end of the basket, the struts being arranged to define an opening at the distal end, the basket having an expanded state and a collapsed state. A core wire with a distal end and a proximal end is able to reciprocate through the opening at the distal end of the basket. A filter bag is attached only at the distal end of the core wire, the filter bag being located distally to the distal end of the basket when in the collapsed state. The method further comprises moving the core wire relative to the basket to expand the basket and the filter bag in a deployed state downstream from the stenotic lesion to capture emboli during treatment of the stenotic lesion.
