ParaCor Heat Exchanger

ParaCor is a new high performance heat exchanger intended for precise blood and crystalloid cardioplegia delivery.


The highly efficient device has a static priming volume of only 28ml and employs a counter current blood to water flow direction, proven to maximise heat transfer efficiency in a reduced space1,2.
