Abstract
A device (1) functions for treating malignant, tumorous tissue areas. The device has at least one measuring sensor for determining chemical or physical signal patterns in the immediate vicinity of the tumor cells or similar tissue part, a control unit and at least one treatment assembly, which has as an active agent release element for chemically influencing and/or treatment electrodes for physically influencing the tumorous tissue area to be treated. The sensor(s), the active agent release element, and the treatment electrodes are connected to the control unit for a physical and/or chemical treatment of the tumorous tissue area, controlled as a function of the measured values of the tumor cells. The device is constructed in the form of a swallowable capsule or dragee, and a sensor is provided for detecting release parameters. The control unit is designed with a threshold value switch for activating the active agent release element and/or the electrodes when a predetermined target value is exceeded.
