Patent ID: 7867247

Claim:
A method for embolic protection during treatment of a stenotic lesion in a body vessel, the method comprising: disposing an embolic protection device in an undeployed state in the body vessel, the device comprising: 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, the core wire being able to reciprocate through the opening at the distal end of the basket; and a filter bag 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; and 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, the filter bag being disposed over substantially the entire basket when in their respective expanded states defining the deployed state.
