Abstract
Aspects of the present invention provide miniaturized cryoprobes having shaft diameters up to 2 mm and including a stiffening element that may act as a grip for manipulation of the cryoprobe. Various aspects of the present disclosure are generally directed towards apparatuses, systems, and methods that may include a cryoprobe: In certain instances, the cryoprobe may include an elongate shaft and an operating head having an expansion chamber. The elongate shaft may include a first passageway configured to provide high pressure gas to the expansion chamber, a second passageway for evacuating gas from the expansion chamber, and a vacuum chamber coaxially arranged around the first passageway and the second passageway.
