Abstract:
A device (1, 1a, 1b, 1c, 1d) for treating malignant, tumorous tissue areas, comprising at least one measuring sensor (9) for determining chemical or physical signal patterns in an immediate vicinity of a tumorous tissue area, a control unit, and at least one treatment assembly having at least one active agent supply container (4), a dosing element with dosing control, and an active agent release element (6) for chemically influencing and/or treatment electrodes for physically influencing the tumorous tissue area to be treated, wherein the sensor(s)(9), the active agent release element(6) and/or the treatment electrodes (3) are connected to the control unit for controlling a physical and/or chemical treatment of the tumorous tissue area as a function of measured values of the tumor cells with continuous follow-up dosing of the active agent to be applied, wherein the device is constructed in a form of a swallowable capsule or a dragee and has a sheath (11) which at least covers the sensor(s)(9), the sheath being removable at least over a certain area under the influence of bodily fluid, wherein the control unit and a sensor for detecting release parameters are designed with a threshold value switch for activating the active agent release element and/or the electrodes when a predetermined target value is exceeded, and wherein at least one heat resistor (18) is provided within the active agent supply container (4) for heating up and release of the active agent.
