Abstract
A cryoablation tool has a primary fluid circuit for cryogenically cooling or heating tissue surrounding the distal portion of the cryoablation tool. The primary fluid circuit has a primary-primary heat exchanger facilitating recuperative heat exchange between a high pressure stream of a primary fluid and a low pressure stream of the primary fluid. The cryoablation tool has a secondary fluid circuit having a secondary-secondary heat exchanger for permitting recuperative heat exchange between a high pressure stream of a secondary fluid and a low pressure stream of the secondary fluid. The secondary fluid circuit also has a primary-secondary heat exchanger permitting heat exchange between the high pressure stream of the primary fluid and the low pressure stream of the secondary fluid.
