摘要: The present invention provides a cryogenic device and system for treating biological tissue, which includes at least two media-flow lumens media-expansion element cooling media flowing within the device. A portion of is located along one lumens. construction suitable good contact with tissue selected treatment. Preferably, employ or more closed pathways efficient recycling employed. also efficacious heat-exchange relationships between conduits optimal cooling. are particularly designed formation lesions in most particularly, deep, elongated continuous cardiopulmonary tissue. method using treatment
