Abstract
A method and system for feedback control for cryo-mapping and cryoablation are disclosed. According to one aspect, a cryo-mapping and cryoablation control system includes a first control device configured to receive a target parameter value and a measured output parameter and to output an injection pressure target signal based on a first difference between the target parameter value and the measured output parameter. The system also includes a second control device configured to receive the injection pressure target signal and to output a valve control signal, the valve control signal being used to set a position of an injection pressure valve. The first control device is configured to determine a value of the injection pressure target signal to drive the first difference toward zero.
