EMBOLIC PROTECTION DEVICE AND METHODS OF USE
First Claim
1. An embolic protection device for placement in an arterial system of a human, the arterial system having an ascending aorta, an aortic arch, and a descending aorta, wherein a brachiocephalic artery ostium and at least one of a left common carotid artery ostium and a left subclavian artery ostium branch from the aortic arch, comprising:
- a filter having a delivery configuration and a deployed configuration, the filter having—
a first filter section having a first cross-sectional dimension in the deployed configuration sufficient to anchor the embolic protection device within the ascending aorta and to provide passage of a therapeutic device through the first filter section; and
a tapered second filter section extending proximally from the first filter section; and
a proximal portion extending proximally from the second filter section to an extracorporeal location.

Abstract
Embolic protection devices for placement in an arterial system of a human and methods of using such devices. In one embodiment, the device includes a filter having a first filter section configured to be deployed along the ascending aorta and aortic arch, a tapered second filter section extending proximally from the first filter section, and a proximal portion extending proximally from the second filter section. The second filter section is configured to be deployed along the descending aorta, and the proximal portion extends to a position below a renal artery. The embolic protection device can be configured to continuously filter the arterial system blood between a distal end of the first filter section to a position within the arterial system downstream of the renal artery.

24. A method for providing embolic protection throughout the vasculature of a patient, including the arterial system having an ascending aorta, an aortic arch, and a descending aorta, and ostium from the aortic arch, comprising:
-
delivering a distal region of an embolic protection device to a portion of the ascending aorta and a proximal region of the device to the descending aorta; expanding the embolic protection device to contact at least a portion of the arterial system distal to the brachiocephalic artery ostium; and retaining emboli along a length of the embolic protection device extending from a point distal to the brachiocephalic artery ostium to an extracorporeal location. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32)
