  • Patent number: 11659836
    Abstract: An apparatus, a system, and methods for receiving, perfusing and maintaining and assessing excised donor heart physiological functionality. The system generally comprises an apparatus for receiving and holding an excised heart that is interconnected with: (i) a perfusate-processing system, (ii) a bi-directional perfusate pumping system, (iii) flow sensors for monitoring the flow of perfusate to and from an installed heart's aorta, pulmonary artery, pulmonary vein, and vena cava, (iv) an ECG apparatus interconnectable with the installed heart, and (v) probes interconnecting the installed heart with instruments for monitoring the heart's physiological functionality using load independent indices and load dependent indices.

  • Publication number: 20220346368
    Abstract: An organ perfusion system (100) for extracorporeal perfusion of a heart (1) includes an organ chamber (15) having an aortic connector (17), and a first fluid flow path (19) comprising a pump interface (23) and an oxygenator (25), the aortic connector being fluidly connected to the first fluid flow path. The system is adapted for use in a method, wherein oxygenated perfusate is flowed into the heart via the aorta and desoxygenated perfusate is allowed to exit the heart via the inferior vena cava and/or the superior vena cava to thereby perfuse the heart in a substantially unloaded state. Such method may allow for improved recovery of the heart tissue during perfusion. The organ perfusion system may further comprise a perfusate reservoir (27) and/or a chassis, wherein the organ chamber is pivotable with respect to the chassis for holding the heart in a tilted position or to allow rotation of the organ chamber in a horizontal plane.

  • Publication number: 20120041256
    Abstract: An apparatus provides short-term cardiac support after cardiac surgery using a cardiopulmonary bypass (CPB) pump (or heart-lung machine) having a pump coupled to a pump controller for pumping oxygenated blood through a cannula into the patient The pump controller controls the pump in a first mode to generate pulsatile flow of the oxygenated blood to the patient, and in a second mode to provide counter-pulsatile flow of blood through the cannula synchronized with the heart of the patient, whereby, when the heart of the patient is in diastole, the pump forces blood from the cannula into the patient, and when the heart is in systole, the pump removes blood from the patient via the cannula.
