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.

Abstract: Ablation devices and methods for determining a degree of contact between an electrode and a target tissue are disclosed. An example ablation device for treating body tissue may include a catheter having a proximal end region and a distal end region. An electrode may be disposed adjacent to the distal end region of the catheter. The device may also include a processing unit having a memory. The processing unit may be in electrical communication with the electrode. The processing unit may be capable of determining a degree of contact between the electrode and a target tissue.
