  • DUAL LUMEN CANNULA WITH EXPANDABLE LUMEN
    Publication number: 20260021236
    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.

  • DUAL LUMEN DRAINAGE CANNULA WITH SINGLE OUTLET
    Publication number: 20220184292
    Abstract: A dual lumen drainage cannula configured for use in a veno-arterial extracorporeal membrane oxygenation (VA ECMO) system includes a first drainage tube having a proximal end, a distal end, and at least one aperture defined in the distal end. The dual lumen drainage cannula further includes a second drainage tube having a proximal end, a distal end, and at least one aperture defined in the distal end. The dual lumen drainage cannula further includes an outlet fitting in fluid communication with the first drainage tube and the second drainage tube. The distal end of the second drainage tube is joined to a portion of the first drainage tube between the proximal and distal ends of the first drainage tube.
