The CryoShape cryoprobe (U.S. Patent 6,503,246) is a hand-held cryosurgical instrument for destroying deep tissue of Keloids and Hypertrophic Scars through surgical intralesional intervention utilizing extremely cold cryoprobe.
The device is based on intralesional application of a needle cooled by liquid nitrogen with boiling temperature of -196°C (-320.8°F) to the scar core to effect cellular and microcirculation destruction.
Optimal freezing/thawing rates improve fibroblasts destruction while blocking microcirculation in the tissue, two mechanisms which contribute to excellent clinical results.
The CryoShape set comprises the following components:
The components, which are in contact with patient’s skin, are made of biocompatible materials.
The freezing needle ensures complete deep-freezing of the inner scar tissue. The especially designed structure provides excellent thermal conductivity and easily penetrating into the hard, rubbery and dense scars tissue.
Based on a concentric double-lumen unit with excellent thermal conductivity, liquid nitrogen passes the CryoShape twice, for improved operation and efficacy, without any contact with the patient.
The novelty of the CryoShape is in its specially elongated design enabling easy penetration into the rubbery and dense scars tissue, i.e., treating the scar from its roots!
