摘要： A cryogenic probe for ablating cardiac tissue is provided comprising a handle piece and an elongated probe tube extending from the handle that terminates in a malleable end effector closed at its distal end and having a smooth outer surface. A semi-rigid insulative sleeve extends from the handle and overlies the proximal portion of the probe tube. An internal support preferably in the form of a coiled spring is located interior of the probe tube for supporting the interior surface of the probe tube. A plurality of cryogenic fluid supply tubes are disposed on the interior of the probe tube for introducing cryogenic fluid to the probe tube, each supply tube having an outlet orifice, with the outlet orifices being staggered along the length of the probe tube. In one embodiment, the probe tube is axially movable relative to the sleeve/handle between retracted and extended positions. Also, the probe tube may be provided with a thermocouple for measuring the temperature of the surface of the probe tube.
