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.

Feedback control system for cryo-mapping and cryoablation

A device, system, and method for performing a variety of treatment procedures safely with a single treatment device. For example, a system is provided that includes a treatment device with a highly conformable balloon that is inflated at a constant pressure and that remains 'soft' during use, which enhances balloon-tissue contact, treatment efficacy, and patient safety. In one embodiment, a system for ablating tissue comprises: a treatment device including a highly conformable balloon; a control unit including a fluid supply reservoir in fluid communication with the highly conformable balloon, the control unit being configured to deliver fluid from the fluid supply reservoir to the highly conformable balloon such that the highly conformable balloon is maintained at a balloon pressure of between 0.2 psig and 3.0 psig.
