ABSTRACT:
A small, self-contained, disposable cryosurgical probe has a pencil-like housing with a refrigerant-containing cartridge in the housing and a hollow tip projecting from the housing. A small diameter capillary tube has one end in the housing opposite the cartridge and its other end extending into the tip with the intervening length of the tube formed into a multi-turn coil. The refrigerant is conducted from the cartridge through the tube to the probe tip and the temperature of the refrigerant is stabilized so as to maintain a substantially uniform mass flow rate of refrigerant through the tube to the tip.
