Infrared Coagulation: Infrared Coagulation therapy is another effective technique for removing hemorrhoids that are not too large. With this procedure, a local anesthetic is applied followed by an infrared coagulation device that is brought into contact with the hemorrhoid. The protrusion is heated for a brief interval, causing tissue to be burned. The necrotic (dead) tissue then forms a scar inhibiting the flow of blood to the Hemorrhoid.
