Apparatus and methods for protecting against embolization during endovascular heart valve replacement
First Claim
1. Apparatus for protecting against embolization during endovascular replacement of a patient'"'"'s heart valve, the apparatus comprising:
- 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 to divert emboli away from the patient'"'"'s cerebral vasculature without capturing the emboli within the filter.

Abstract
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.
