    Abstract: An extension cannula for use with a conventional ECMO return cannula is provided. The extension cannula includes a flexible conduit transitionable between a collapsed insertion state and an expanded deployed state when in communication with blood flow from an ECMO machine via the ECMO return cannula. The extension cannula may be positioned through a conventional ECMO return cannula such that the proximal end of the flexible conduit is disposed within and proximal to the end of the ECMO return cannula, while the distal end of the flexible conduit is disposed in a patient's thoracic aorta to deliver oxygenated blood directly to the patient's thoracic aorta via one or more pores at the distal region of the flexible conduit to improve cerebral oxygenation, maintain systemic arterial pulsatility, and reduce the potential for end-organ injury.
