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.

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.

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 ...

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.

Transbronchial Lung Biopsy Using Cryoprobes

Archivos de Bronconeumología (English Edition), 2010
Transbronchial lung biopsy (TBLB) is a bronchoscopy procedure used to obtain peripheral lung tissue. Small size samples and artefacts lead to variable, and usually poor, diagnostic yield. The use of cryoprobes may enable larger size and better quality biopsy samples to be obtained.

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.

Retinal Cryoprobe in Orbital Tumor Management

American Journal of Ophthalmology, 1975
We used the retinal cryoprobe in the surgical management (biopsy and excision) of orbital and ocular adnexal tumors in four patients. The strong bond between the cryoprobe tip and the tumor allowed application of moderate traction to the tumors, facilitating their removal.
