Abstract
A flexible-resilient heat exchanger that is designed to be disposed inline of a cardioplegia tubing set for heating or cooling blood and/or cardioplegia solution. The heat exchanger comprises a flexible-resilient inner tube defining an inner flow path for blood and/or cardioplegia solution, for example, and a flexible-resilient outer tube surrounding the inner tube. The outer tube has fluid inlet and outlet ports so as to define an outer flow path between the inner and outer tubes for heat exchanging fluid, for example. The outer tube is sealingly connected to the inner tube adjacent opposite ends of the outer flow path, and the inner tube defining a barrier between the first and second fluids while permitting heat transfer between the first and second fluids.
