Embodiment Construction

[0064] Figure 1A A first embodiment of a retrograde blood flow system 100 is shown, adapted to establish and promote retrograde or reverse blood flow circulation in the region of the carotid bifurcation in order to limit or prevent the release of emboli into the cerebral vasculature. , especially into the internal carotid artery. The system 100 interacts with the carotid artery to provide drainage from the carotid artery to a venous site, such as the internal jugular vein (or in alternative embodiments from the carotid artery to another drainage site, such as another great vein or an external container) - countercurrent. The retrograde blood flow system 100 includes an arterial access device 110 , a venous return device 115 , and a shunt tube 120 . The shunt tube 120 provides a channel for retrograde blood flow from the arterial access device 110 to the venous return device 115 . A flow control assembly 125 interacts with the shunt tube 120 . The flow control assembly 125 ...

Abstract

Devices and methods for establishing and promoting retrograde or retrograde blood circulation in the region of the carotid bifurcation in order to limit or prevent release of emboli into the cerebral vasculature, such as into the internal carotid artery. The method is used in particular for interventional procedures performed by a transcarotid approach or transfemoral access 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...
