The CryoShape is intended to destroy tissue during surgical procedures by applying extreme cold.

The CryoNeedle Cryoprobe manufactured by Etgar Group H.M.Y.A. Ltd. (U.S Patent 6.503,246) is a hand-held cryosurgical instrument for destroving tissue during surgical procedures by intralesional application of extremely cold cryoprobe. The device is based on intralesional application of a needle cooled by the cryogenic fluid (liquid nitrogen with boiling temperature -196℃ (-320.8ºF)) to a selected area to effect cellular destruction. . The needle is cooled by the cryogenic fluid (liquid nitrogen - boiling temperature -196°C (-320.8°F)) is applied intralesionally to a selected area to effect cellular destruction. By forcing liquid nitrogen to circulate through the needle an ice ball around the CryoNeedle developed causing the abutted HSK tissue to be completely frozen. As this iceball grows, its leading edge advances through tissue. Tissue that comes into contact with the iceball is destroyed. Temperatures of -25℃ to -50℃ (-139F to -58°F) are achieved within 30 seconds.
