Embodiment Construction

[0056] For the following defined terms, these definitions shall apply unless a different definition is given in the claims or elsewhere in this specification.

[0057] It is assumed herein that all numerical values ​​are modified by the term "about", whether expressly stated or not. The term "about" generally refers to a range of numbers that one of skill in the art would consider equivalent to the recited value (ie, having the same function or result). In many instances, the term "about" may be expressed including numbers that are rounded to the nearest significant figure.

[0058] The recitations of numerical ranges by endpoints include all numbers subsumed within that range (eg, 1 to 5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, and 5).

[0059] While some suitable dimensional ranges and / or values ​​are disclosed for various components, features and / or specifications, those skilled in the art, motivated by the present invention, will appreciate that desired dimensions, range an...

Abstract

Disclosed are methods and devices for isolating all three of the left subclavian, left common carotid and brachiocephalic arteries from embolic debris that might flow through the aortic arch, via a single access point. A system may include an elongate flexible tubular sheath, having a proximal end and a distal end, and an inner member extending through the sheath and moveable relative to the sheath. A left subclavian element may be supported by the inner member. A filter membrane may be configured to isolate the aorta from the brachiocephalic, left common carotid and left subclavian arteries when the left subclavian element is expanded within the left subclavian artery and the sheath is retracted to expose the membrane. The left subclavian element may include a self expandable frame, whichmay carry a left subclavian filter.

Description

[0001] Cross References to Related Applications [0002] Pursuant to 35 U.S.C. §119, this application claims the benefit of priority to U.S. Provisional Application Serial No. 62 / 663,117, filed April 26, 2018, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention generally relates to a medical device for filtering blood. And, more particularly, in certain embodiments, the present invention relates to methods and systems of filters and deflectors for protecting cerebral arteries from dislodged emboli, debris, etc. during endovascular or cardiac surgery. Background technique [0004] Thromboembolic diseases, such as stroke, pulmonary embolism, peripheral thrombosis, atherosclerosis, etc., affect many people. These diseases are a leading cause of morbidity and mortality in the United States and throughout the world. Thromboembolic events are characterized by vascular occlusion. Occlusion can be caused by a viscoela...
