Intravascular filtering device

摘要

System suitable for an intravascular procedure within a vessel of a patient's vascular system. The system comprises a guidewire with a filter element at the distal end, the filter element being expandable from a collapsed configuration when the element is unrestrained. A balloon catheter is able to slide along the guidewire. The balloon can be expanded within the region of stenosis to generate embolic material that can be captured by the filter element.
