Abstract
A method of pressurizing the right ventricle of the heart. The method includes providing a multi-lumen cannula. The multi-lumen cannula includes a first sub-cannula and a second sub-cannula. The first sub-cannula includes a proximal end, a distal end, a lumen extending between the proximal and distal ends, and proximal and distal fluid apertures formed in the lumen. The second sub-cannula includes a proximal end, a distal end, a lumen extending between the proximal and distal ends, and proximal and distal fluid apertures formed in the lumen. The distal fluid apertures of the two lumens are spaced from one another along the axial length of the multi-lumen cannula. The method further includes inserting the cannula into the vasculature system of a patient so that the distal fluid aperture of the lumen of the second sub-cannula is received in one of the right atrium, the superior vena cava, and the inferior vena cava. The distal fluid aperture of the lumen of the first sub-cannula is received in the right ventricle. The method of pressurizing the right ventricle still further includes fluidly connecting the proximal fluid apertures of the first and second sub-cannulas to a fluid conducting pump for moving fluid through the two sub-cannulas.
