It was previously reported that Alcor is designing a new integrated cardiopulmonary bypass system for its air transportable perfusion (ATP) system. During cryopreservation cases, the ATP takes over the function of the patient’s own heart and a heat exchanger in the heart-lung machine reduces the patient’s temperature to a few degrees above the freezing point of water. Blood is also replaced with an organ preservation solution that is specially designed to support life at low temperature.
This ATP design, still under evaluation, has several advantages. For instance, it uses a centrifugal pump, which is significantly safer than peristaltic pumps because they make it much more difficult to create dangerously high pressures and are much less prone to passing massive gas emboli (air bubbles).
