Methods for embolic protection during treatment of a stenotic lesion in a body vessel
First Claim
1. 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.

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.

13. A method for embolic protection during treatment of a stenotic lesion in a body vessel, the method comprising:
-
introducing a balloon catheter within a body vessel; disposing an embolic protection device in a collapsed state within an inner lumen of the balloon catheter, the device comprising; a set of wires including a first section arranged as struts that define a basket with a distal end and a proximal end, the struts at the distal end of the basket being arranged to define an opening, the basket having a collapsed state and being configured to move to an expanded 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 having a collapsed state and being configured to move to an expanded state; advancing the device beyond a distal end of the balloon catheter; and deploying the device in an expanded state downstream from the stenotic lesion to capture emboli during treatment of the stenotic lesion, wherein deploying the device includes moving the core wire relative to the basket to expand the basket and the filter bag, the filter bag being disposed over substantially the entire basket when in the expanded state. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
