Abstract: A process and device is described for therapeutically treating hemorrhoids extending from the anal canal wall of a patient. The device includes a stable, anal canal suppository appliance for intimately contacting the anal canal wall and hemorrhoids. The appliance has sufficient length to extend from the anus to the rectum and sufficient diameter to intimately contact the wall tissues without overly stretching the sphincter muscles. The appliance contains an internal electrical resistor for generating heat in response to the application of electrical energy. The device has a portable case containing an electrical energy storage battery and a control circuit for controlling the application of the electrical energy to the resistor to maintain the temperature of the appliance above body temperature and below 45.degree.
