The Argon Beam Coagulator is a surgical tool used in various surgeries. The Argon Beam Coagulator destroys tissues with an electrical current passed through a stream of argon gas. This tool may be used to coagulate or to burn and destroy residual, microscopic, malignant (cancerous) cells after a tumor has been removed. It is successful at achieving non-contact hemostasis with minimal thermal injury of adjacent or underlying tissues.
