Cannula and Balloon System for Extracorporeal Membrane Oxygenation

Abstract

The present disclosure provides for a cannula and balloon system for extracorporeal membrane oxygenation. The system may comprise one or more cannula, one or more insertion mechanism, and one or more balloon cuff. The method may comprise venous-venous or venous-arterial insertion into one or more blood vessels or chambers of the heart. The balloon cuff may allow fluid flow to avoid oxygenated blood restriction to a region of the body for the cannula insertion duration. One or both the balloon cuff and dual cannula may prevent occlusion, recirculation, and mixing of oxygenated and deoxygenated blood. When there is a dual cannula, the cannula may comprise a reinfusion cannula and a drainage cannula. A reinfusion cannula may bypass one or more chambers of the heart. When the system comprises more than one cannula, the cannulae may be joined via a cannula connection mechanism.
