Patent ID: 8303490

Claim:
A capsule type medical device, comprising: a capsule shaped casing which can be ingested to within the living body; an electrical stimulation device which comprises a plurality of electrodes which are used for applying electrical stimuli to living body tissue; an electrode selection device which selects an electrode from among the plurality of electrodes, to apply an electrical stimulus; a contact detection device which electrically detects the electrode from the plurality of electrodes, and the detected electrode being in contact with the living body tissue for applying the electrical stimulus, the contact detection device being a force detection device; and a control section which controls the electrical stimulation device, electrode selection device, and contact detection device, the control section being configured to determine that the electrode for applying the electrical stimulus does not contact the living body tissue when a contact pressure value obtained from the force detection device is smaller than a predetermined value, and the control section being configured to determine that the electrode for applying the electrical stimulus sufficiently contacts the living body tissue when a contact pressure value obtained from the force detection device is greater than the predetermined value, and to electrically contact the electrode for applying the electrical stimulus with the electrical stimulation device.
