A gastrointestinal electrode device is disclosed, comprising an electrode head intended to be implanted in a stomach wall for emission or reception of electrical signals and a flexible cable with an outer isolation layer. The flexible cable is connected to the electrode head for forwarding the electric signals to an external side of the electrode device. The electrode head comprises flexible expandable retention means and at least one electrode contact area arranged to cover at least a part of the outer electrode head area. Further the expandable retention means are automatically expandable from an condition of insertion into an expanded condition for opposing retraction of the electrode via the aperture of insertion, thus making the electrode attachable to the living organ. The electrode head further comprises an abutment area and the electrode device further comprises a relatively rigid introduction part, arranged to engage with the abutment area of the electrode head for percutaneous introduction of the catheter into a stomach wall into a stomach wall via an aperture, wherein the introduction part is releasable from the electrode head after insertion, whereby the electrode head remains implanted in the stomach wall.
