Directional cryoablation system

A cryoablation system having a directional activated state and a non-directional activated state, the cryoablation system comprising:

• a cryoablation probe to ablate a target site comprising:
• a shaft having an outer surface, an inner surface, a distal portion, a proximal portion, a first side, and a second opposing side;
• an active region at the distal portion of the shaft, the active region comprising a cooling compartment located at the first side of the shaft and a heating compartment located at the second opposing side, the cooling and heating compartments thermally insulated from one another to minimize energy losses therebetween such that ice is selectively formed at the target site in a directional activated state of the cryoablation system, wherein:
• the cooling compartment comprises:
• an exhaust tube comprising a capillary tube disposed therein and configured to guide a fluid or gas that exhibits a Joule Thomson cooling effect through the shaft;
• a heat exchanger coil disposed over the capillary tube;
• at least one temperature sensor disposed adjacent to the exhaust tube;
• and
• the heating compartment comprises:
• a heater plate;
• at least one temperature sensor disposed adjacent to the heater plate;
• and
• a heater cartridge located between the exhaust tube and the heater plate and comprising a a heater zone;
• and
• a controller operably connected to the cryoablation probe, the controller comprising a processor and a memory, the memory having computer-executable instructions stored thereon that, when executed by the processor, cause the controller to:
• process temperature measurement data from the at one temperature sensor of the heating compartment and the at least one temperature sensor of the cooling compartment;
• and
• regulate the heater zone of the heater cartridge based on the temperature measurement data processing to maintain a temperature that is sufficiently constant to mitigate or prevent formation of ice on the heating compartment in a directional activated state of the cryoablation system.
