Abstract
Devices, systems, and methods for maintaining cryoballoon size, cryoballoon pressure, and/or coolant flow rate based on physical characteristics of the tissue to be ablated. In one embodiment, a cryoablation system comprises: a cryoablation device, the cryoablation device including: an expandable treatment element defining an interior chamber; and a pressure sensing system at least partially within the interior chamber; a fluid flow path including at least one valve that is in communication with at least one PID device; and a control unit including processing circuitry in communication with the pressure sensing system and the at least one PID device, the processing circuitry being configured to: determine a target pressure of the expandable treatment element based on a target size of the expandable treatment element; and determine a target flow rate of coolant through the fluid flow path based on the target pressure of the expandable treatment element.
