摘要： A system and kit for using a source of low-pressure refrigerant for a cryotherapy procedure and for subcooling a cryotherapy refrigerant. The system may generally include a fluid reservoir and a fluid flow path in thermal exchange with the fluid reservoir, the fluid flow path including a first thermal exchange device in thermal exchange with the fluid reservoir, a compressor in fluid communication with the first thermal exchange device, a condenser, a reversing valve located between the compressor and the condenser, a second thermal exchange device located between the reversing valve and the compressor, and an expansion valve located between the condenser and the thermal exchange device. The third thermal exchange device may be configured to be in fluid communication with the cryotherapy console and configured to place a secondary refrigerant within the first fluid flow path in thermal communication with a secondary refrigerant of the cryotherapy system.

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.

摘要： A system (10) and method for controlling the inflation, ablation, and deflation of a balloon catheter (1) is provided. The system includes a balloon catheter (1), a console (20) having a pressurized gas or liquid inflation source, and an umbilical system (12) to deliver pressurized coolant to the balloon catheter (1). The system (10) comprises a PID (Proportional Integral Derivative) controller or other pressure-sensing device that monitors the amount of pressure and volume within the balloon catheter. During inflation, the pressure and/or volume of fluid within the balloon (23) is maintained at a target amount in order to provide sufficient mechanized pressure against the desired target region. The system limits the inflation pressure such that a safe quantity of gas would be released should a leak occur. If the amount falls below a certain threshold level, gas or fluid egress is presumed and the inflation process is halted.

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 system and method is disclosed for cryogenic medical treatment, having a stabilizer for a reservoir of cryogenic fluid. Accordingly, the stabilizer allows the reservoir some limited range of motion to enhance accuracy of a load sensor engaged by the reservoir, and to resist tipping or other undesirable movement by the reservoir. The stabilizer may allow the reservoir a range of vertical movement, and may limit the reservoir to a range of positions or alignments relative to the load sensor. Additional configurations are disclosed, providing stabilizers of various types and features.
