MANAGING DELIVERY OF REFRIGERANTS TO MEDICAL DEVICES

Systems and methods for controllable delivery of pressurized refrigerant to a medical device, such as a cryoablation catheter. In some examples, a delivery system includes a tank holding the pressurized refrigerant, an electrical heater arranged to heat the tank, and an electronic controller connected to regulate the heater based on input signals received from a plurality of sensors including a temperature sensor in thermal contact with the exterior surface of the tank and a pressure sensor for measuring pressure in the refrigerant-delivery line connecting the tank to the medical device. In operation, the electronic controller processes the input signals by comparing values of at least some of the input signals with respective threshold values and uses logic operations configured for combined processing of two or more of the input signals to decide when to switch the heater between an ON state and an OFF state.
