Embolic protection during percutaneous heart valve replacement and similar procedures
First Claim
1. A method for providing embolic protection during an endovascular procedure on a patient'"'"'s heart, the method comprising:
- delivering one or more vascular filter elements with guide structure through the right subclavian artery to position the one or more vascular filter elements or components thereof into the right carotid artery or the brachiocephalic artery and into the left carotid artery to filter flow into both carotid arteries from the aorta,wherein the guide structure spans between the brachiocephalic artery and the left carotid artery with at least a portion of the guide structure extended into the left carotid artery and with at least a portion of the guide structure extending in a distal direction from the distal end of the one or more vascular filter elements.

Abstract
Various devices are described to provide filtering of flow from the aorta to the left carotid artery and the right carotid artery. The filters can be brought into a desired position through one or more peripheral arteries. A single filter device can provide the desired filtering or a plurality of devices can be used. In particular a single filter device can span between the brachiocephalic artery and the left carotid artery. These filter devices can be used effectively to capture emboli generated during procedures on the heart so that emboli do not travel to the patient'"'"'s brain where the emboli can cause a stroke or other adverse event. In particular, these filters can be used during percutaneous procedures on the heart, such as endovascular heart valve replacement.

23. A method for the endovascular replacement of a heart valve, the method comprising:
-
delivering one or more vascular filter elements with a guide structure through the right subclavian artery to position the one or more filter elements or components thereof into the right carotid artery or the brachiocephalic artery and into the left carotid artery to filter flow through both carotid arteries while the guide structure spans between the brachiocephalic artery and the left carotid artery with at least a portion of the guide structure extended into the left carotid artery; and delivering a heart valve delivery catheter through the descending aorta or the left subclavian artery to the heart to effect at least a step related to removal of a heart valve or the placement of a prosthetic heart valve. - View Dependent Claims (24, 25, 26)
