Abstract:
A method of pressurizing the right ventricle of the heart, the method comprising:providing a multi-lumen cannula comprising:a first sub-cannula including 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; anda second sub-cannula including a proximal end, a distal end, a lumen extending between the proximal and distal ends, and proximal and distal fluid apertures formed in a lumen, wherein the distal fluid apertures of the two lumens are spaced from one another along the axial length of the multi-lumen cannula;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, and the distal fluid aperture of the lumen of the first sub-cannula is received in the right ventricle; andfluidly 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.
