Abstract
Apparatus and methods for performing cryogenic ablation of tissue and adjusting the size and/or location of a cryogenic cooling region. A cooling assembly may include tubes for dispensing and exhausting a coolant or refrigerant. One or both of the tubes may be moved, e.g., slidably adjusted, in order to adjust the location or size of a cryogenic ablation region. The cooling assembly may be integrated into cryogenic ablation devices including a cryogenic balloon device that includes an inner inflatable balloon and another balloon that is at least partially wrapped around the inner balloon and carries refrigerant for performing cryo-ablation. Electrodes permit electrical mapping of tissue before or after cryo-ablation to verify success of the procedure.
