Benefits of technology

[0034]As used herein, “installation in an aorta,” or “installed in an aorta” is meant that the device is set in its intended functional position within an aorta, e.g., such that emboli are prevented from passing into a branching vessel.

Problems solved by technology

When this occurs, potentially harmful particulates, such as emboli, may be released into the blood stream.
These particulates can be damaging, e.g., if they restrict blood flow to the brain.
Devices to block or divert particulates from flowing into particular regions of the vasculature have been proposed but may not eliminate the risks associated with the release of potentially harmful particulates into the blood stream during or after particular medical procedures.
Improved devices for blocking or diverting vascular particulates are under development, but each intravascular procedure presents unique risks.

examples

[0082]In the following description, various examples of the disclosure will be described. For purposes of explanation, specific examples are set forth in order to provide a thorough understanding of at least one example of the disclosure. However, it will also be apparent to one skilled in the art that other examples of the disclosure are not limited to the examples described herein. Furthermore, well-known features or processes may be omitted or simplified in order not to obscure examples of the disclosure described herein.

[0083]Reference is made to FIG. 1A, a schematic diagram of a side-view of a device 100 including a frame 10, and catheter attachment 15 in an intrinsic configuration. The device 100 includes a frame 10 to hold a filter and define the area, shape, and curvature of the filter. In this diagram, the back lateral portion of the frame 10 is hidden from view by the front lateral portion of the frame 10. The frame 10 includes intrinsic superior curves 13, 14 at both the ...

Abstract

An intra-aortic device comprising a filter and a frame defining the shape of the filter, wherein the frame is intrinsically curved in a superior direction by a proximal superior bend and / or a distal superior bend, whereupon installation in an aorta, the frame flattens.

Description

BACKGROUND OF THE INVENTIONField of the Invention[0001]The present disclosure relates to intra-aortic devices and methods to prevent emboli from entering arteries branching from the aorta, e.g., arteries that lead to the brain.Description of the State of the Art[0002]Various medical procedures may perturb blood vessels or surrounding tissues. When this occurs, potentially harmful particulates, such as emboli, may be released into the blood stream. These particulates can be damaging, e.g., if they restrict blood flow to the brain. Devices to block or divert particulates from flowing into particular regions of the vasculature have been proposed but may not eliminate the risks associated with the release of potentially harmful particulates into the blood stream during or after particular medical procedures.[0003]Improved devices for blocking or diverting vascular particulates are under development, but each intravascular procedure presents unique risks.[0004]As intravascular devices an...
