Cryogenic Dispensing System and Method for Treatment of Dermatological Conditions

A method of treating dermatological conditions such as a wart or the like, comprising the steps of:

• providing a cryogenic dispersing system having:
• a cartridge comprising liquid cryogenic material of limited dose;
• and
• a dispensing device having a housing;
• said housing containing an intermediate interior portion adapted to receive said cartridge,
• said intermediate interior portion defining an engineered flow path between said cryogenic material in said cartridge and outlet opening, and a valve capable of starting the flow of cryogenic material;
• said housing containing extended legs for spacing of the exit end of the engineered flow path from the dermal surface to be treated.
• said extended legs containing a method of mounting a masking ring;
• placing said masking ring in contact with the dermal surface to locate the outlet opening proximate to said dermatological condition;
• and
• allowing said liquid carbon dioxide to flow through said engineered flow path to said outlet opening and onto said dermatological condition.
