Abstract

See full text

A cryogenic catheter system provides safe and effective treatment of tissue. The system includes a catheter that is coupled to a console via fluid and electrical umbilicals. The console controls the overall operation of the system based to provide and maintain a predetermined temperature at the catheter tip. The console also controls and monitors operating parameters for providing warning indications to the user and terminating operation of the system in the event of a failure that may compromise patient safety.
