Embodiment Construction

[0111] For the following defined terms, unless a different definition is given in the claims or elsewhere in this specification, these definitions shall apply.

[0112] Herein, all numerical values ​​are assumed to be modified by the term "about", whether expressly stated or not. The term "about", in the context of a numerical value, generally refers to a range of numbers that one of ordinary skill in the art would consider equivalent to the recited numerical value (eg, having the same function or result). In many instances, the term "about" may include figures that are rounded to the nearest significant figure.

[0113] The recitation of numerical ranges by endpoints includes all numbers subsumed within that range (eg, 1 to 5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, and 5).

[0114] While some suitable dimensional ranges and / or values ​​are disclosed in relation to various components, features and / or specifications, those skilled in the art will appreciate the desired dimension...

Abstract

Vascular filters and deflectors and methods for filtering bodily fluids. A blood filtering assembly can capture embolic material dislodged or generated during an endovascular procedure to inhibit or prevent the material from entering the cerebral vasculature. A blood deflecting assembly can deflect embolic material dislodged or generated during an endovascular procedure to inhibit or prevent the material from entering the cerebral vasculature.

Description

[0001] Cross-references to related literature [0002] This application claims priority to US Provisional Patent Application 62 / 720,816, filed August 21, 2018, which is hereby incorporated by reference in its entirety. technical field [0003] Generally, the present invention relates to medical devices for filtering blood. And, more particularly, in some embodiments, the present invention relates to a method and system of filters and deflectors for protecting cerebral arteries from emboli, debris, etc. dislodged during intravascular or cardiac surgery. Background technique [0004] There are four arteries that carry oxygenated blood to the brain, the left and right vertebral arteries and the left and right common carotid arteries. Various procedures performed on humans such as transcatheter aortic valve replacement (TAVR), aortic valvuloplasty, carotid artery stenting, left atrial appendage occlusion, mitral annuloplasty, mitral Valve replacement, mitral valve repair, tho...
