Abstract
A cannulation system for cardiac support uses an inner cannula disposed within an outer cannula. The outer cannula includes a fluid inlet for placement within the right atrium of a heart. The inner cannula includes a fluid inlet extending through the fluid inlet of the outer cannula and the atrial septum for placement within at least one of the left atrium and left ventricle of the heart. The cannulation system also employs a pumping assembly coupled to the inner and outer cannulas to withdraw blood from the right atrium for delivery to the pulmonary artery to provide right heart support, or to withdraw blood from at least one of the left atrium and left ventricle for delivery into the aorta to provide left heart support, or both.
