摘要： A cryoablation system includes thermally insulated containers for holding liquid refrigerant. The containers are placed in a docking station that charges the containers with a liquid refrigerant at a cryogenic temperature suitable for carrying out a surgical procedure. The charged containers are detachably connectable with an inlet line of a cryoablation probe. When the cryoprobe is activated, the chilled liquid refrigerant is transported from a delivery container, through the cryoprobe, and to a recovery container. The recovery container is preferably identical in design to the delivery container. The refilled recovery container is then placed in the docking station to charge. In another embodiment, a cartridge includes a delivery container and recovery container combined as a single unit. Methods are also described.

摘要： Single phase liquid refrigerant cryoablation systems and methods are described herein. The cryoablation systems drive liquid cryogen or refrigerant along a closed fluid pathway without evaporation of the liquid cryogen. A cryoprobe includes a distal energy delivery section to transfer energy to the tissue. A plurality of cooling microtubes positioned in a distal section of the cryoprobe transfer cryogenic energy to the tissue. The plurality of microtubes in the distal section are made of materials which exhibit flexibility at cryogenic temperature ranges, enabling the distal section of the cryoprobe to bend and conform to variously shaped target tissues.
