Description of the system CRYOCATH's CRYOCATH technology from MEDTRONIC combines the advantages of cardiac catheter ablation and cardiac ablation CRYOCATH from MEDTRONIC produces cryogenic (extremely cold) controlled conditions in the cooling segment of a long, flexible and bi-directional catheter. The system delivers cryogenic temperatures to the internal walls of a latent heart approaching the heart through the body vasculature from a puncture in the skin. The procedure is done to correct electrophysiological abnormalities that lead to irregular or erratic heartbeats. This selectively destroys (performs ablation) groups of cardiac cells (sites generating the arrhythmia), which causes or propagates the abnormality. System is composed of the console, catheters, electrical and gas connectors (called as umbilicals) and other accessories. The figure below shows the components connected to form the system. Crio universal console: the console houses the electronic components and the software to control and record the procedure, stores and controls the delivery of liquid refrigerant under high pressure through the umbilical cable coaxial to the catheter, recovers the expanded vapor from the catheter refrigerant under vacuum, and Disposes the refrigerant through the hospital waste management system. The hardware controls the safety monitoring system while the software supplies the patient information, user interface, procedure temperature, temperature / time set point in automatic mode and information from Procedure data. Electric umbilical cable: the sterile electric umbilical cable is a cable
