Title: Cryosurgical catheter

Abstract: A cryogenic catheter includes an elongate, contiguous, thermally-transmissive region coupled to the catheter, the thermally-transmissive region being sufficiently flexible to change from a linear configuration to an arcuate configuration. The thermally-transmissive region may include a plurality of interconnected thermally-transmissive segments that are generally cylindrical in shape. The cryogenic catheter may be in fluid communication with a fluid source, and may include one or more fluid injection tubes. Further, an injection tube may be slidably disposed within the catheter so that the injection tube is longitudinally movable relative to an outer surface of the catheter. The cryogenic catheter may also be in communication with a controller programmed to regulate delivery of a cryogenic fluid from the fluid source to the medical device.
