Cryogenic Medical System

A cryogenic medical system for use in patient treatment procedures, said cryogenic system comprising:

• at least one cryoengine including a dewar containing a cryogen, a flow generator within said dewar;
• at least one pressurization system having one or more heaters arranged therein, at least one port, one or more control valves, a first vessel and a second vessel interconnected, wherein said first vessel is submersed in said cryogen and has a first temperature and said second vessel is positioned outside said cryogen and has a second temperature greater than said first temperature;
• at least a first attachment connecting said flow generator to said port of said pressurization system, and one or more cryolines connected to said port;
• and
• one or more cryoinstruments comprising one or more tubular structures arranged therein, said cryoinstruments each having a proximal end which connects with said cryolines of said cryoengine and a distal end positioned at a treatment site;
• wherein said pressurization system produces supercritical cryogen, pressurized cryogen, or one or more pseudo-fluids, alone or in combination.
