Abstract
A dual lumen drainage cannula configured for use in a VA ECMO system includes a first drainage tube having a proximal end, a distal end, and at least one aperture in at least one wall of the first drainage tube proximate to the distal end of the first drainage tube, and a second drainage tube having a proximal end, a distal end, and at least one aperture in at least one wall of the second drainage tube proximate to the distal end of the second drainage tube. The first drainage tube passes through the second drainage tube. The dual lumen drainage cannula also includes a sleeve positioned adjacent to an interior wall of the second drainage tube. The sleeve is formed of a flexible material so as to be expandable and collapsible within the second drainage tube.
