UHP Argon and Helium
UHP Argon and Helium are gases commonly used in a process called Cryoablation. This process allows diseased tissue to be targeted and destroyed using cryogenic liquids to freeze acute areas of tissue via cryoprobes (hollow needles) which are inserted near the infected site. Once the cryoprobes are in place, cryogenic liquids are used to super-cool the tips of the cryophobes, and thus, the immediate area surrounding those tips. By this method, the defective area of tissue is destroyed without harming the surrounding, healthy tissue.
Medical professionals believe that cryoablation is effective in treating diseased prostate tissue, fibroadenomas, and cardiac tissue that is causing arrythmias
Liquid Helium is also commonly used as the main magnet cooling agent in Magnetic Resonance Imaging (MRI) systems.
