Methods and systems for establishing retrograde carotid arterial blood flow

Abstract

Devices and methods establish and facilitate retrograde or reverse flow blood circulation in the region of the carotid artery bifurcation in order to limit or prevent the release of emboli into the cerebral vasculature such as into the internal carotid artery. The methods are particularly useful for interventional procedures performed through a transcarotid approach or transfemoral into the common carotid artery.

Description

[0001] References to related applications [0002] This application claims the co-pending U.S. Provisional Patent Application Serial No. entitled "METHODS AND SYSTEMS FOR ESTABLISHING RETROGRADE CAROTID ARTERIAL BLOOD FLOW" and filed April 10, 2015 Priority of No. 62 / 145,809. Priority is claimed on the above filing date and the Provisional Patent Application is hereby incorporated by reference in its entirety into this application. [0003] background technical field [0004] The present invention generally relates to medical methods and devices. More particularly, the present invention relates to methods and systems for accessing the carotid vessel and establishing retrograde blood flow during the performance of carotid stenting and other procedures. Background technique [0005] Carotid artery disease often involves the deposition of plaque P, which separates the common carotid artery CCA from the internal carotid artery ICA—an artery that supplies blood flow to the bra...
