Double-Lumen Percutaneous Femoral Cannula for Extracorporeal Membrane Oxygenation

摘要

A double-lumen percutaneous femoral cannula for extracorporeal membrane oxygenation (ECMO) is an apparatus that is used to perform an ECMO procedure in non-ideal conditions. The apparatus may include at least one first cannula and at least one second cannula of different sizes that are arranged to form a single structure. By providing a single structure instead of several separate components, the apparatus makes the insertion of the apparatus easier and reduces the risk of the apparatus dislodging while the patient is being transported. The at least one first cannula and the at least one second cannula are preferably elongated tubular structures designed to prevent the recirculation of oxygenated blood. The at least one first cannula is designed to enable the aspiration of deoxygenated blood, while the at least one second cannula is designed to enable the pumping of oxygenated blood back into the body.
