Bidirectional arterial cannula for extracorporeal membrane oxygenation and method of using such a cannula

摘要

Arterial cannula for extracorporeal membrane oxygenation and method of using such a cannula The invention relates to an arterial cannula (20) for ECMO comprising: a main arterial cannula (22) having an inner wall (31) and having a first end (24) with a blood outlet (26), the first end being intended to be introduced into an artery in order to inject blood retrograde in the artery, and a retro-perfusion cannula (30) configured to be movable in translation between a retracted position in the first end of the main arterial cannula and a position deployed at least partially outside the main arterial cannula, opposite to the main arterial cannula blood outlet.
