Abstract: Apparatus, consisting of a probe, containing a lumen and having a distal end configured to contact tissue of a living subject. A temperature sensor is located at the distal end, and a pump, having a pump motor, is coupled to deliver a cryogenic fluid through the lumen to the distal end of the probe and to receive the cryogenic fluid returning from the probe. There is a separator, coupled to separate the returning cryogenic fluid into a returning cryogenic liquid and a returning cryogenic gas, and a flow meter, coupled to measure a rate of flow of the returning cryogenic gas. A processor is configured to control a rate of pumping of the pump motor in response to a temperature measured by the temperature sensor and the rate of flow of the returning cryogenic gas.

Abstract: A system (e.g., an ultrasound imaging system) is provided. The system includes an ultrasound probe having a cable, and an ultrasound probe holder configured to receive the ultrasound probe. The system further includes a housing supported by a base. The housing includes a connector port and a cable manage passage. The cable manage passage positioned at an upper end of the housing distal to the base. The cable extending through the cable manage passage and is attached to the connector port. The ultrasound probe holder is coupled to a front side of the housing.

Abstract: Cryogenic apparatus, consisting of a connector that has a connector base plate configured for connection to a conduit carrying a cryogen, and a slot extending across the base plate. The apparatus has a plug, which is configured for insertion into an opening in the base plate. The apparatus also has a latch plate that is configured to slide within the slot between a first position, in which the plug is inserted through an aperture in the latch plate into the opening, and a second position, in which a cryogenic probe is inserted through the aperture and brought into fluid communication with the opening. There is a sensor, which is coupled to control a flow of the cryogen through the conduit by detecting whether the latch plate is in the first position or the second position.

Abstract: Apparatus, consisting of a single insulated container, configured to contain a cryogen. The apparatus also has a first pump and a second pump, both disposed in the single insulated container and configured to pump the cryogen from the single insulated container while immersed in the cryogen. A first probe and a second probe, having respective first and second proximal ends, are coupled to receive concurrently the cryogen pumped by the first pump and the second pump, respectively. The probes have respective first and second distal ends, which are chilled by the cryogen received through the first and second proximal ends and which are configured to be inserted into a body of a living subject.

Abstract: Apparatus, including a probe, containing a first lumen and a second lumen and having a distal end that contacts tissue of a living subject. A fluid supply delivers a cryogenic fluid through the first lumen to the distal end and receives cryogenic fluid returning via the second lumen. A temperature sensor is located at the distal end. A pressure sensor located at a proximal end of the first lumen measures a pressure of the cryogenic fluid. A processor controls a delivery rate of the cryogenic fluid from the fluid supply, so that, when a temperature measured by the temperature sensor is less than a preset guard temperature, the delivery sate is a preset low rate, and when the temperature measured by the temperature sensor is greater than or equal to the preset guard temperature, the delivery rate is set in response to a pressure measured by the pressure sensor.
