coblation is a non-heat driven process. RF energy is applied to conductive medium (usually saline), causing a highly focused plasma field to form around the electrodes. The plasma field is comprised of highly ionized particles. These ionized particles have sufficient energy to break organic molecular bonds within tissue. The by-products of this non-heat driven process are elementary molecules and low molecular weight gases.
Instead of exploding tissue, coblation causes a low temperature, molecular disintegration. The result is tissue removal with minimal collateral necrosis.
