摘要： A device, system, and method for performing a variety of treatment procedures safely with a single treatment device. For example, a system is provided that includes a treatment device with a highly conformable balloon that is inflated at a constant pressure and that remains "soft" during use, which enhances balloon-tissue contact, treatment efficacy, and patient safety. In one embodiment, a system for ablating tissue comprises: a treatment device including a highly conformable balloon; a control unit including a fluid supply reservoir in fluid communication with the highly conformable balloon, the control unit being configured to deliver fluid from the fluid supply reservoir to the highly conformable balloon such that the highly conformable balloon is maintained at a balloon pressure of between 0.2 psig and 3.0 psig.

摘要： A system for the recovery of expanded refrigerant from a cryotreatment system for storage and disposal may generally include first fluid flow path having a first compressor and a fluid recovery reservoir, and a closed-loop second fluid flow path having a thermal exchange device that is in thermal communication with the fluid recovery reservoir, a second compressor, and a condenser. The first fluid flow path may include a primary refrigerant from a cryotreatment system and the closed- loop second fluid flow path may contain a secondary refrigerant for cooling the primary refrigerant within the fluid recovery reservoir. The refrigerant recovery conduit may be in fluid communication with both the cryotreatment system and a medical facility scavenging system. The refrigerant recovery conduit and the cryotreatment system may be located within the same cryotreatment console.

摘要： A method for purging a cryotreatment system, in particular, for clearing moisture and thus preventing ice blockages within a fluid flow path that may be formed when moisture pockets within the fluid flow path of the system are encountered by a first injection of refrigerant at the beginning of a cryotreatment procedure. The method may include injecting refrigerant from a refrigerant source into a fluid delivery conduit at a preselected pressure for a first period of time, the refrigerant flowing from the fluid delivery conduit through a fluid injection element and into a fluid recovery conduit, and evacuating refrigerant from the fluid recovery conduit by vacuum pressure generated by the vacuum pump for a second period of time. This method may be repeated for a plurality of cycles.
