EMBOLIC PROTECTION DEVICE AND METHODS OF USE

摘要

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.

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; anda 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.
