Abstract
A cryomedical device, comprises a probe which is adapted to be positioned to rapidly cool a body portion of a patient, and which is connected to a coolant supply which supplies coolant thereto at a predetermined rate. Means are provided for sensing the temperature in the vicinity of the probe, for example, a thermocouple element in the probe itself or a needle which may be injected into the body, and one, or both of these are connected to a control for regulating the supply of coolant. In addition, a heater may be provided in the probe and the control may be connected to regulate the heater. In the preferred arrangement, the control includes a device for setting the temperature value of operation which is connected to a comparator to provide a control between the set value and the actual value of the temperature of the body in the vicinity of the probe.
