Abstract
A disposable cassette for a cardioplegia system for delivering cardioplegic solution to the heart during open heart surgery in cooperation with an extracorporeal blood circuit employing a heart/lung machine, includes a conduit diverting a portion of the blood flow from the heart/lung machine to a cardioplegia delivery line. A heat exchanger for controlling fluid temperature is provided in the cardioplegia delivery line. A first pump combines the blood from the conduit with a second fluid and delivers the combined flow into the delivery line leading to the heat exchanger. A control panel is operatively connected for adjusting the ratio of blood and second fluid delivered by the first pump and for adjusting the total volumetric rate of flow from the first pump.
