Single expandable double lumen cannula assembly for veno-venous ECMO

摘要

The present invention provides an apparatus, system, and method of use of a simple, less invasive, self-expandable percutaneous double lumen cannula assembly for VV ECMO that overcomes the limitations and obstacles of the techniques described above. The present invention achieves near theoretical total venous blood drainage, total extracorporeal gas exchange, and prevents recirculation and multiple cannulation, thereby simplifying VV ECMO, decreasing surgical and blood trauma, and expanding its application.
