Isotherm of alcohol-cooled cryoprobe

Brain Research Bulletin, 1979
The spread of cooling from the tip of a cryoprobe placed in the ventral posterior lateral nucleus of the thalamus in 10 cats was determined. A 20 degrees C isotherm was described as having a diameter of 4 mm and extending 2 mm below the tip of the cryoprobe and tapering up along the shaft of the cryoprobe for a distance of 2 mm, when the cryoprobe tip ...

A self-contained neurosurgical cryoprobe

Biomedical Engineering, 1977
A cryoprobe with an interchangeable container (vessel) holding the cryoprobe has been designed, this enabling it to dispense with the use of hoses to deliver the coolant to and remove it from the Dewar vessel and the vacuum pump. The cryogenic action provided for by a single ampoule lasts 5 minutes.

Cryoprobe treatment of acne conglobata

British Journal of Dermatology, 1974
SUMMARY Twenty-five patients with acne conglobata were treated with cryotherapy delivered via probes. The probe was applied to nodular lesions for 20–25s without pressure. Freon, carbon dioxide and nitrous oxide were found to be therapeutically equivalent.

Cryoprobe Isotherms: A Caveat and Review

Journal of Endourology, 2010
Cryotherapy is a form of thermal therapy for the treatment of small renal masses, particularly in high-risk patients. However, optimal application and the critical temperature for in vivo cell death have not been well established. Additionally, most centers do not currently monitor temperature during the procedure.

Freezing Capacity of a Cryoprobe

Archives of Ophthalmology, 1968
Cryoprobe capacity can be compared using the weight of ice formed by freezing the surface of distilled water at 37 C. The effect of increasing the area of contact while still maintaining a constant tip temperature is illustrated. The thermal characteristics of the contact plate alter the amount of water or tissue frozen.

The Joule Thomson Cryoprobe

Archives of Ophthalmology, 1967
A cryoprobe working on the Joule Thomson principle using the expansion of carbon-dioxide gas is described. It is the first cryoprobe that can be applied to the lens at ambient temperature (room temperature) having almost instantaneous freezing and rewarming characteristics. Iris adhesion and laceration are virtually impossible.

A Transilluminating Retinal Cryoprobe

Archives of Ophthalmology, 1968
ONE OF the problems in the treatment of retinal tears by the application of cyrocongelation is the precise localization of the freezing relative to the hole. Often the freezing does not appear in the center of the mound produced by indentation of the cryoprobe.

A New 20-Gauge Intravitreal Cryoprobe

American Journal of Ophthalmology, 1980
A new intraocular 20-gauge (0.89-mm) cryoprobe is compatible with the Ocutome-Fragmatome system. The iceball forms only at the tip and there is a rapid freeze and defrost cycle. Actual clinical testing during vitreous surgery showed the probe to be reliable and easy to use.

Increasing the sensitivity of cryoprobe protein NMR experiments by using the sole low-conductivity arginine glutamate salt [PDF]

Journal of Magnetic Resonance, 2008
Decrease in experimental sensitivity of cryoprobe experiments for salty samples, attributed to increased sample conductivity, has been a long-standing issue in protein NMR.
