Abstract
An apparatus and method for automatic operation of a refrigeration system (10) to provide refrigeration power to a catheter for tissue ablation or mapping. The primary refrigeration system (208) can be open loop or closed loop, and a precool loop will typically be closed loop. Equipment and procedures are disclosed for bringing the system to the desired operational state, for controlling the operation by controlling refrigerant flow rate, for performing safety checks, and for achieving safe shutdown.
