ABSTRACT:
A cardioplegia system in which cardioplegia medication or a mixture of arterial blood and medication is delivered to the heart of a patient undergoing open heart surgery. A cooling system incorporates flat coils vertically disposed in upright tanks in which the level of cooling liquid is controlled and thus the percentage area of the coil which is immersed. This permits the control of the cooling while isolating the blood or medication from the cooling system.
