Aortic occlusion device
First Claim
1. An aortic occlusion device, comprising:
- a radially expandable and collapsible proximal end portion and a radially expandable and collapsible distal end portion, wherein the distal end portion comprises a substantially conical portion, and the proximal and distal end portions are configured to radially expand within an aorta to secure the device within the aorta;
a catheter extending axially between the distal end portion and the proximal end portion;
a porous covering positioned around the catheter and between the proximal end portion and the distal end portion; and
a one-way valve positioned between the substantially conical portion of the distal end portion and the proximal end portion of the device and configured to restrict retrograde blood flow through the device toward the heart.

Abstract
Embodiments of aortic occlusion devices are described herein that include radially expandable and collapsible proximal and distal end portions, such as annular self-expanding stents or frames, that are configured to radially expand within an aorta to secure the device within the aorta. The devices can also include a catheter extending axially between the distal end portion and the proximal end portion and a porous covering, or filter, positioned around the catheter and between the proximal end portion and the distal end portion and configured to filter emboli from blood flowing into upper-body arteries. The device can further include a one-way valve positioned at or adjacent to the distal end portion of the device and configured to restrict retrograde blood flow through the device toward the heart.
