    摘要： Apparatus for protecting a patient against embolization during endovascular replacement of the patient's heart valve is provided, the apparatus including a replacement valve configured for endovascular delivery and deployment, and an embolic filter configured for disposal downstream of the replacement valve during deployment of the valve. Apparatus including a delivery catheter having an expandable replacement valve disposed therein, and an embolic filter advanceable along the delivery catheter for diverting emboli released during endovascular deployment of the replacement valve is also provided. Furthermore, methods for protecting a patient against embolization during endovascular replacement of the patient's heart valve are provided, the methods including the steps of endovascularly delivering a replacement valve to a vicinity of the patient's heart valve, endovascularly deploying an embolic filter downstream of the heart valve, and endovascularly deploying the replacement valve.

    摘要： Vascular embolic filtering systems, as well as methods for using the same, are provided. In general, the subject invention includes a system comprised of an embolic filter assembly and a multiple lumen delivery and retrieval sheath, where the embolic filter assembly includes a guide wire with an embolic filter operatively coupled to the distal end of the guide wire for capturing emboli created during interventional procedures within a target vessel. Features of the subject invention provide for the rapid exchange and deployment of embolic filters in a patient's vasculature.
